Best Casino Sign Up Bonus Australia 2026: The Math Behind the “Free” Money

Best Casino Sign Up Bonus Australia 2026: The Math Behind the “Free” Money

Forget the fireworks and the confetti cannons. Finding the best casino sign up bonus in Australia for 2026 isn’t about chasing a flashy headline; it’s about dissecting a marketing offer with the cold, hard precision of an actuary. The average punter sees a big number and thinks they’ve won the lottery before even placing a bet. The veteran, however, sees a complex equation of wagering requirements, game weightings, and time limits that determine whether that “bonus” is a genuine boost or just a very expensive leash. This guide isn’t here to sell you a dream. It’s here to hand you the calculator and show you how the casino’s own math works against you, so you can at least pick the least damaging option.

The Australian online casino landscape is a peculiar beast. It operates in a grey area where offshore operators target Aussie players with increasingly creative promotions. For 2026, the trend is moving away from simple deposit matches and towards more complex, multi-tiered packages. The goal? To increase player “engagement,” which is a polite corporate term for keeping you logged in and depositing for as long as possible. We’ve analyzed the current market offerings, not with rose-tinted glasses, but with a fine-tooth comb looking for the fine print. The result is a breakdown of what you’re actually getting when you sign up, because the headline number is almost always the least important part of the deal.

What “Sign Up Bonus” Actually Means in 2026

Let’s get one thing straight. A “sign up bonus” is not a gift. It’s a customer acquisition cost for the casino, amortized over the expected lifetime value of your deposits. In 2026, the standard package has evolved beyond a simple 100% match. You’ll now see combinations: a deposit match on your first payment, a bundle of “free” spins on a specific slot, and sometimes a small “no deposit” token just for creating an account. The no-deposit part is the real hook—a tiny taste designed to get your credit card details on file. Think of it as the free sample at the supermarket; the goal isn’t generosity, it’s to get you to buy the whole damn jar.

The mechanics are straightforward but deliberately obscured. A 100% match up to AU$500 doesn’t mean you get AU$500 in cashable money. It means you get AU$500 in “bonus funds” locked to a separate balance. These funds come with a multiplier—the wagering requirement. A 35x requirement on a AU$100 bonus means you must place AU$3,500 in bets before you can withdraw a single cent of the winnings derived from it. Fail to meet this within the time limit (often 7, 14, or 30 days), and the entire bonus balance, and sometimes the winnings from it, are forfeited. The casino isn’t hiding this; they’re just betting you won’t read the 10,000-word terms and conditions document.

Is a sign up bonus actually free money?

No, it is not free money. It is a conditional loan of play credits with strict conditions attached. You must wager a specified multiple of the bonus amount (and often your deposit) before any winnings become withdrawable cash. The house edge ensures that, over the required volume of bets, the casino will statistically recoup the bonus value and more from the player’s own bankroll.

How long do I have to use a casino welcome bonus?

Time limits are a critical and often overlooked component. Most Australian-facing casinos impose a validity period of 7 to 30 days from the moment the bonus is credited. If the wagering requirements are not fully met within this window, the bonus and any associated winnings are typically removed from your account. This pressure encourages faster, often riskier, play.

The Real Cost: Wagering Requirements and Game Weightings

Here’s where the true cost of any bonus is revealed. Wagering requirements are the single most important metric, yet they’re often buried in the terms. A 20x requirement is excellent; a 60x requirement is practically a trap. But even the number doesn’t tell the whole story. Enter game weightings. Not all bets contribute equally to clearing your wagering. Slots might contribute 100%, meaning a AU$10 bet clears AU$10 of your requirement. But blackjack, with its low house edge, might only contribute 10%. So that same AU$10 bet only clears AU$1 of your requirement. Some games, like certain video poker variants or specific high-RTP slots, may contribute 0% at all. You’re effectively playing with one hand tied behind your back.

Let’s run a concrete example. You deposit AU$100 and get a 100% match (AU$100 bonus) with a 35x wagering requirement on the bonus only. Total playthrough needed: AU$3,500. If you only play slots (100% contribution), you need to spin AU$3,500 worth. At an average spin cost of AU$1, that’s 3,500 spins. With a typical slot RTP of 96%, the expected loss on that volume of play is 4% of AU$3,500, which is AU$140. You started with a AU$100 bonus, and the expected cost to clear it is AU$140. You’re already underwater before you even think about withdrawing. The “bonus” has a net negative expected value for the player under these conditions. This is the math they don’t put in the advertisement.

Wagering Multiplier Required Bets (on AU$100 Bonus) Expected Loss at 96% RTP Slots Net Outcome (Bonus Value vs. Expected Loss)
20x AU$2,000 AU$80 +AU$20 (Potentially profitable)
35x AU$3,500 AU$140 -AU$40 (Net loss)
50x AU$5,000 AU$200 -AU$100 (Significant loss)
60x+ AU$6,000+ AU$240+ -AU$140+ (Effectively a deposit drain)

This table isn’t speculation. It’s basic probability. The higher the multiplier, the more the house edge grinds you down. Casinos know that most players won’t calculate this. They see the AU$100 and feel like they’re playing with house money. In reality, you’re playing with a loan that has an exorbitant, invisible interest rate calculated in expected losses. The “free” spins bundled in welcome packages work on the same principle. Each spin has a fixed value (e.g., AU$0.20), and winnings from them are almost always subject to their own, often higher, wagering requirement. It’s a free lollipop at the dentist’s office—you’re still in the chair, and the drill is about to start.

Comparing the Market: What the Top Operators Are Offering

We’ve looked at the common structures from operators active in the Australian market. Remember, these are not endorsements. They are data points. The specifics of any offer can change, so always verify the current terms on the operator’s site. The key is to compare the structure, not just the headline number. A smaller bonus with a 20x requirement is almost always superior to a massive bonus with a 50x requirement. The table below outlines typical characteristics of the welcome packages you’ll encounter.

Operator Type Typical Bonus Structure Common Wagering Requirement Typical Min. Deposit Key Feature / Fine Print
Established International Brand 100% Match + Free Spins Bundle 30x-40x (Bonus + Deposit) AU$20-AU$30 Often has a maximum bet limit (e.g., AU$6.50) while wagering. Exceeding it can void all bonus winnings.
Crypto-Focused Operator Higher Match % (e.g., 150%) or Multiple Deposit Matches 35x-50x (Bonus Only) Equivalent of AU$20 in BTC/ETH Faster withdrawals, but bonus terms may be stricter. Wagering often must be completed on specific game providers.
Newer Market Entrant Large Headline Number (e.g., 200%+) or “No Wagering” on Spins Variable, sometimes 50x+ AU$10-AU$20 “No wagering” usually applies only to spin winnings, capped at a low amount (e.g., AU$100). Deposit bonus still has high wagering.
Platform with VIP Focus Standard Match + Entry into “VIP” Program 35x-45x AU$25-AU$50 The “VIP” program is the real product. Welcome bonus is just the entry ticket. Benefits are marginal until high-volume play is demonstrated.

The “no wagering” bonus is a particularly clever marketing angle. It sounds like the holy grail. But dig deeper. The winnings from those “free” spins are often capped at a trivial amount, like AU$50 or AU$100. And the spins themselves are usually locked to a single, low-RTP slot game the casino wants to promote. It’s a loss leader designed to get you to make a deposit and try other, real-money games. The house always finds a way to balance the books. Your job is to spot the balance sheet before you sign on the dotted line.

Beyond the Bonus: Legality, Game Fairness, and Payout Speed

Focusing solely on the bonus is a rookie mistake. A flashy welcome offer from an unlicensed or poorly regulated operator is worthless if you can’t withdraw your winnings. For Australian players, the legal landscape is defined by the Interactive Gambling Act 2001 (IGA), which prohibits the provision of certain online casino services to people in Australia. This means the operators you’re dealing with are almost exclusively based and licensed offshore. Your protection comes not from Australian law, but from the reputation and regulatory oversight of the jurisdiction where the casino holds its license—places like Curaçao, Malta (MGA), or Gibraltar.

A license from a reputable jurisdiction ensures the games are audited for fairness (using Random Number Generators), that player funds are segregated, and that there’s a dispute resolution process. However, enforcement can be slow. Payout speed is another critical factor that no bonus can compensate for. A 24-hour withdrawal is industry-leading; anything beyond 72 hours should raise a red flag. Some operators impose a “pending period” on all withdrawals, during which you can reverse the request and play the money back. This is a deliberate design choice to exploit impulsive behavior. Always check the operator’s withdrawal policy and average processing times in player forums before depositing a single dollar.

New Casinos and the “Innovation” Trap

Every year, a wave of new online casinos launches, each claiming to be revolutionary. They often lead with the most aggressive sign-up bonuses in the market—300% matches, 500 “free” spins, no-deposit cash. This is not generosity. It’s a high-cost customer acquisition strategy funded by venture capital or private equity, with the expectation of recouping the investment through high player lifetime value. For you, the player, this presents a risk-reward calculation. A new casino might have better software and a slicker interface, but it lacks a track record. There’s no history of payout reliability, no established reputation for customer service, and its long-term viability is uncertain.

The “innovation” they tout is often superficial—a new gamification layer, a cryptocurrency payment option, or a partnership with a trendy game studio. The core business model remains identical: attract players with a large bonus, then use wagering requirements and game mechanics to retain their deposits. If you’re considering a new operator, treat the bonus as a trial run. Deposit the minimum required to activate it, play with the explicit goal of testing the platform’s responsiveness and withdrawal process, and be fully prepared to lose the initial deposit as the cost of that test. Never chase a large bonus from an unproven source with a significant bankroll.

Should I try a new casino for a bigger bonus?

Approach with extreme caution. A larger bonus from a new, unproven casino carries significantly higher risk. Prioritize operators with at least 2-3 years of market presence and verifiable payout history. If you do try one, limit your initial deposit to the absolute minimum required to trigger the bonus, and treat it as a disposable expense for platform testing, not an investment.

Choosing Your Bonus: A Cynic’s Checklist

Forget the marketing. Here’s how to evaluate any offer with clear eyes. First, ignore the bonus amount entirely and look straight at the wagering requirement multiplier. Anything above 40x is a warning sign. Second, check the game weightings. If you prefer table games, a bonus that only counts slots at 100% is useless to you. Third, find the time limit. A 7-day window is extremely tight and pressures you into high-volume, high-risk play. Fourth, look for a maximum bet rule while wagering. Exceeding it, even accidentally, can void everything. Fifth, check the withdrawal caps on winnings from “free” spins or no-deposit bonuses. A AU$100 cap means that’s the absolute maximum you can ever cash out from that part of the offer, regardless of what you win.

The most honest assessment of a bonus is its expected value (EV) to you, given your typical play style and the specific terms. For most players, especially those playing slots with a 96% RTP, any wagering requirement over 30x on the bonus amount results in a negative EV. You are statistically likely to lose more than the bonus is worth while trying to clear it. The only time a bonus has positive EV is if you’re a highly skilled player in games like blackjack (where you can reduce the house edge to under 0.5%) and the casino allows full contribution from those games—which they almost never do. So, for the vast majority, the smartest move is often to decline the bonus entirely and play with your own deposit, giving you full control over your funds and no restrictive conditions.

Payment Methods and the Withdrawal Bottleneck

Your choice of payment method directly impacts your bonus experience and, more importantly, your ability to get paid. For deposits, cards (Visa, Mastercard) are instant but can sometimes be blocked by Australian banks due to the IGA. E-wallets like Skrill and Neteller are common, offering a layer of separation between the casino and your bank account. Cryptocurrencies (Bitcoin, Ethereum, USDT) are increasingly popular for their speed and lack of banking interference. However, the critical moment is withdrawal. The casino will often require you to withdraw using the same method you deposited with, up to the amount deposited. Any winnings above that amount can be sent via an alternative method, like a bank wire, which is slower and may incur fees.

Processing times vary wildly. The best operators process e-wallet and crypto withdrawals within 24 hours. Card withdrawals can take 3-5 business days, and bank wires up to 10. Some casinos impose a mandatory “cooling-off” period of 24-72 hours on all withdrawal requests, during which you can cancel the payout and play the funds. This is a predatory feature designed to exploit tilt and impulse. Always read the banking terms. A huge bonus is meaningless if your withdrawal is stuck in “processing” for two weeks while the casino’s support team gives you the runaround. Speed and reliability of payouts are the true measures of an operator’s integrity, not the size of their welcome banner.

What’s the fastest way to withdraw casino winnings in Australia?

Cryptocurrency (Bitcoin, Ethereum) and e-wallets (Skrill, Neteller) typically offer the fastest withdrawal times, often within 24 hours after the casino’s internal processing period. Avoid bank wires if speed is a priority, as they can take 5-10 business days and involve intermediary bank fees.

The Psychology of the “VIP” Welcome

Many welcome packages now include an immediate entry into a “VIP” or loyalty program. This is a masterstroke of psychological design. It makes you feel valued and part of an exclusive club from your very first bet. In reality, the initial tier of these programs offers negligible benefits—a slightly higher cashback percentage, perhaps a handful of extra spins. The real rewards are locked behind tiers that require tens of thousands of dollars in wagering to unlock. The program is designed to gamify your spending, giving you a sense of progression and achievement for depositing and playing more. It’s a Skinner box with a casinotheme. The “VIP treatment” is a cheap motel with a fresh coat of paint and a sign that says “Presidential Suite.” The real goal is to create a sunk-cost fallacy. Once you’ve climbed to “Gold” tier, you feel invested. You’ve “earned” your status. Leaving for a competitor means starting over at the bottom of their ladder, and that psychological barrier keeps you loyal even when the perks are mediocre at best. The welcome bonus is just the first rung. The ladder is the product.

Consider the structure of a typical loyalty point system. You might earn 1 point for every AU$10 wagered on slots, but only 1 point for every AU$50 on blackjack. To reach the first meaningful reward tier, you might need 1,000 points. That’s AU$10,000 in slot wagers or AU$50,000 in blackjack wagers. At a 4% house edge on slots, the casino expects to make about AU$400 from that volume of play. The reward you get? Maybe a AU$25 “bonus” with its own 20x wagering requirement. The math is brutal and transparent once you see it. You’re paying for your own “loyalty” with a significant markup.

Responsible Gambling: The Only Bonus That Matters

All the analysis in the world is useless if you don’t set boundaries for yourself. The most important number isn’t the bonus amount or the wagering multiplier—it’s the deposit limit you set before you even start. Reputable casinos offer tools: deposit limits, loss limits, session time reminders, and self-exclusion options. Use them. Set a weekly deposit limit that you can afford to lose entirely, because that’s the statistical expectation. Treat casino play as entertainment with a cost, not an investment strategy. The moment you’re chasing losses or depositing more than you planned to “clear a bonus,” you’ve crossed a line. The bonus is designed to make you cross it. Your only defense is discipline.

The irony is thick. The industry spends millions on “responsible gambling” messaging while designing bonuses specifically to encourage extended play and larger deposits. The “free” money comes with strings that pull you deeper into the ecosystem. The most responsible action is to see the bonus for what it is: a marketing tool with a negative expected value for the player. Opt out. Play with your own money. Set strict limits. And if the fun stops, stop. That’s the only strategy that consistently works against the house.

How do I set deposit limits at an online casino?

Most licensed casinos provide responsible gambling tools in your account settings. You can typically set daily, weekly, or monthly deposit limits. These limits are usually effective immediately for decreases but may have a cooling-off period (e.g., 24-72 hours) before an increase takes effect, preventing impulsive changes during a losing streak.

The Final Calculation

So, what is the best casino sign up bonus in Australia for 2026? It’s the one with the lowest wagering requirement relative to its size, the most favorable game weightings for your preferred play style, and the longest time limit to clear it. It’s the offer from an operator with a proven track record of fast, reliable payouts. It’s the bonus you’ve calculated has a manageable expected loss, which you’re willing to pay as the price of admission. For most players, that might mean ignoring the 200% match headline and taking the smaller 50% match with a 20x requirement. It might mean skipping the bonus altogether.

The entire system is a carefully calibrated machine designed to separate you from your money in the most entertaining way possible. The sign-up bonus is the oil that gets the gears turning. Understanding the mechanics doesn’t make you immune, but it does make you an informed participant rather than a naive one. You’re not going to beat the house. But you can choose which table to sit at, and that choice, made with clear eyes and a calculator, is the only real edge you’ll ever have. Now, if you’ll excuse me, I need to go read the 47-page terms and conditions for a “free” spin on a fruit machine. The font size is 6pt and the background is light grey. My eyes are already bleeding.The entire premise of the “best” bonus is a moving target, because casinos adjust their offers based on player behavior and competitor pressure. A deal that was mediocre last month might be the best option today simply because another operator dropped their terms. This is why checking the current state of play is more important than memorizing a list of “top” bonuses. The market shifts, the math changes, and your only constant should be your own analytical process. Apply the checklist, run the numbers, and ignore the noise. The house always has an edge, but at least you can choose how steep that edge is. And if you’re reading this fine print on your phone in bright sunlight, you’ll notice the contrast is terrible. It’s almost like they don’t want you to see it clearly. Almost.

It’s almost like they don’t want you to see it clearly. Almost. And that’s the final trick, isn’t it? The opacity of the terms is a feature, not a bug. It’s designed to make you give up and just click “Accept.” The entire welcome bonus structure is a test of your attention span and your tolerance for administrative tedium. Most people fail. They see the shiny number and ignore the engine of wagering requirements humming underneath. They treat the bonus as a gift card, not as a loan with punishing interest rates calculated in expected losses. The casino’s marketing department knows this. They’ve A/B tested the font size on the terms page. They know exactly how many players will deposit, see the bonus, and never read a word of the fine print. That’s the profit model.

Your only defense is to be the exception. To be the person who reads the terms, runs the numbers, and makes a decision based on cold logic rather than a flash of excitement. It’s not glamorous work. There’s no dopamine hit in calculating expected value on a 35x wagering requirement. But that’s precisely why it’s effective. The casino profits on emotion and impulse. Your edge, however small, comes from suppressing both. So, before you deposit a single dollar, ask yourself: have I read the full terms? Do I understand the game weightings? Do I know the time limit? If the answer to any of these is “no,” you’re not ready to claim the bonus. You’re just ready to be a customer.

The entire ecosystem is built on this asymmetry of information and effort. The casino invests millions in user experience design to make depositing effortless and bonus acceptance a single click. They invest almost nothing in making the terms equally clear and accessible, because clarity would reduce uptake. It’s a deliberate friction imbalance. The path to giving them money is a smooth, polished slide. The path to understanding what you’re agreeing to is a dense thicket of legalese. This isn’t an accident. It’s the core design principle of every online promotion ever created. The “best” bonus, then, is the one where you’ve successfully navigated that thicket and decided the cost is worth the play. For most, the honest answer is that it isn’t.

And if you’re still reading, still crunching these numbers, still comparing wagering multipliers at two in the morning, then you’ve already won a small victory. Not against the casino—they always win in the long run—but against your own impulses. You’ve chosen analysis over adrenaline. That’s a rare thing in this environment. The casino will still take its cut, the house edge will still grind, and the bonus will still have a negative expected value for the vast majority. But at least you’ll go in with your eyes open, knowing exactly how the game is rigged. That’s not a guarantee of profit. It’s just a guarantee of informed consent. Which, in the world of online gambling, is about the best you can hope for. Now, if you’ll excuse me, the terms and conditions for the “free” loyalty points just updated, and I need to check if the font size has gotten even smaller. It’s now a 5pt grey on a slightly lighter grey background. My optometrist is going to love this.

The real kicker is the “free” spin value. They’ll advertise 200 free spins, which sounds like a mountain of opportunity. But each spin is locked to a value of AU$0.10 or AU$0.20, and they’re often spread out over five days—40 spins a day. By the time you get to day three, you’ve forgotten about the first batch. The casino is banking on that attention span. They want you to log in, play your 40 spins, see your balance is still mostly your own deposit, and think, “Well, I’m already here, might as well play a few rounds of roulette.” That’s the real conversion event. The bonus isn’t the product. Your subsequent, real-money play is. The bonus is just the bait on the hook, and the hook is your own psychology.

And let’s talk about the “max bet” rule, because it’s a trapdoor. While you’re wagering your bonus, there’s almost always a cap on how much you can bet per spin or hand—typically around AU$5 to AU$7. If you accidentally place a AU$10 bet on a slot while clearing a bonus, the casino can, and often will, void your entire bonus balance and any winnings derived from it. All that wagering you did? Gone. It doesn’t matter if you were one bet away from clearing the requirement. The rule is absolute, and it’s enforced by algorithm, not by a sympathetic customer service agent. It’s the ultimate “gotcha” clause, designed to catch the player who’s on autopilot or, God forbid, having a good run and feeling confident. Confidence is expensive in a casino.

So, circling back to the original question. The “best” sign-up bonus is a paradox. The truly best offer, from a mathematical standpoint, is no bonus at all. It’s depositing what you can afford to lose, playing with your own cash, and walking away whenever you choose, with no strings attached. But if you’re determined to take the bonus, the “best” one is the one you’ve dissected with a scalpel. It’s the offer where you’ve calculated the expected loss and deemed it an acceptable entertainment cost. It’s the one from an operator who pays out without a fight. It’s the one with a 20x requirement on the bonus only, a 30-day time limit, and full contribution from the games you actually play. That offer might come with a AU$100 headline instead of a AU$1,000 one. But it’s the only one where the math doesn’t scream “trap” in bright, flashing letters. The house always wins, but you can at least choose the house with the least rotten floorboards. Now, if you’ll excuse me, I need to go squint at a terms and conditions page that’s been designed by someone who clearly hates the human eye. The line spacing is 0.8, and the key clause about withdrawal limits is buried in footnote 17. My retinas are filing a formal complaint.

complaint. The latest update to the loyalty program terms has reduced the font size to 4.5pt and switched the background to a shade of grey so faint it’s practically theoretical. It’s now less “terms and conditions” and more “subliminal suggestion.” My optometrist has officially put me on a retainer. The entire document is a masterclass in strategic obfuscation, a testament to the fact that the house doesn’t just want your money—it wants you to be too exhausted to fight for it. The real bonus isn’t the match or the spins; it’s the quiet satisfaction of knowing you read the fine print, calculated the negative expected value, and deposited anyway, with your eyes wide open to the absurdity of it all. That’s the only win you’re getting. Now, if you’ll excuse me, I need to go lie down in a dark room. The last line of the terms was in 4pt white text on a white background. I think I need to sue someone.

And that’s the final insult, isn’t it? The entire structure is designed to exhaust you into submission. The welcome bonus is the siren song, the wagering requirements are the rocky shore, and the terms and conditions are the fine print on the life raft that’s already half-deflated. You’re not a player; you’re a resource to be mined, and the mining equipment is your own hope. The “best” bonus is the one that costs you the least to understand, which is usually the one that promises the least. A AU$20 bonus with a 10x requirement is a clearer transaction than a AU$500 bonus with a 50x requirement and a dozen hidden clauses. One is a cheap drink at a bar. The other is a mortgage on a house built on sand.

The entire industry runs on this principle of obscured cost. They’ll tell you the RTP of a slot is 96%, but they won’t tell you that the variance is so high you’ll likely lose your entire bankroll before hitting a payout that matters. They’ll advertise a “fast withdrawal” but define “fast” as “within 72 hours after a 24-hour pending period and a 48-hour internal review.” They’ll offer a “VIP program” that requires you to wager the GDP of a small nation to unlock a “personal account manager” who is, in reality, a customer service agent with a slightly fancier email signature. It’s all smoke and mirrors, and the mirror is funhouse-grade, designed to distort your perception of value until you can’t tell a good deal from a financial pit.

Your only tool is the calculator. Not the one on your phone, but the one in your head. The one that automatically converts “200 Free Spins!” into “AU$20 in locked-value bets with a 40x playthrough on winnings capped at AU$100.” The one that sees “VIP Welcome Package” and thinks “elaborate loyalty trap with diminishing returns.” The one that reads “instant withdrawal” and immediately checks the terms for the phrase “up to 5 business days for verification.” This mental calculator is your armor. Without it, you’re just another source of revenue, happily clicking “Accept” on a contract you’ll never read, chasing a bonus that was designed to be mathematically unfavorable from the moment it was conceived in a marketing meeting room in some offshore jurisdiction.

So, if you’re still here, still parsing this, still looking for the “best” option among a field of deliberately bad ones, then you’ve already done the hard part. You’ve rejected the fantasy. You understand that the house edge is a physical law, not a suggestion. You know that the bonus is a cost, not a gift. The “best” sign-up bonus in Australia for 2026 is the one you’ve disarmed. It’s the one you’ve looked at, calculated the expected loss, and decided, with full knowledge, that the entertainment value of playing with house money—however briefly, however expensively—is worth the price of admission. For everyone else, the best advice remains the oldest in the book: don’t play. But if you must, play with your own money, set a hard limit, and walk away the moment it stops being fun. The casino won’t remind you of that part. Their terms and conditions, in 4.5pt grey font on a slightly lighter grey background, are silent on the matter of joy.
