The headline is the ad; the terms are the deal
Casino bonuses are contracts written to be skimmed. The banner number: 200% up to $2,000! — is the part designed to stick in your memory; the paragraph below it is the part that decides what you actually collect. Read enough of these offers and a pattern emerges: the biggest headlines tend to carry the heaviest strings, and the offers worth taking are usually the mid-sized, plainly worded ones.
This guide walks through the terms in the order they bite: the wagering requirement first, then game weighting, then the rulebook clauses, max bet, expiry, cashout caps, and finally the structure that decides what happens to the bonus when you finish, cashable or sticky. By the end you’ll be able to price an offer in about two minutes.
Wagering requirements, in plain numbers
A wagering requirement is a multiplier applied to a bonus amount (or a bonus plus deposit, more on that in a moment). It tells you how much you must stake before bonus money becomes withdrawable. Stake means total amount bet, win or lose: it is turnover, not losses. Every $10 spin adds $10 to your progress whether it wins or loses, which is why the same bankroll can be recycled through the requirement many times.
The worked example everyone should run once: a $100 bonus at 35x means $3,500 in total wagers (35 × $100). That is the price of admission, not the cost, the cost depends on what you play and how the terms treat it.
To put $3,500 in context: at $2 per spin and roughly 500 spins an hour, you’re wagering about $1,000 per hour. Clearing the requirement is a three-and-a-half-hour project: longer if you slow down, and much longer if the games you like only count partially.
Bonus-only vs deposit plus bonus
The multiplier has to be applied to something, and the terms will say which:
- Bonus-only: 35x on a $100 bonus = $3,500 to wager.
- Deposit plus bonus: 35x on a $100 deposit plus a $100 bonus = $7,000 to wager.
Same banner, twice the work. This one line in the terms changes the value of an offer more than any other, so find it first.
Game weighting: the multiplier behind the multiplier
Not every wager counts the same. Most sites count slot play at 100 percent, table games such as blackjack and roulette at 10 to 20 percent, and some games, often the ones with the best odds, at zero. Live dealer tables frequently sit in the low-weighting bucket too.
The arithmetic is unforgiving. A $10 blackjack bet on a game weighted at 10 percent counts as $1 toward your requirement. Clearing a $3,500 requirement entirely on blackjack at that weighting would take $35,000 in blackjack bets. Suddenly the “casino-wide” bonus is a slots bonus wearing a costume.
The weighting table usually lives in the bonus terms, sometimes behind a link on the offer page. If you can’t find it, ask support and keep the reply.
The clauses that quietly decide the outcome
Max bet while wagering
Most bonuses cap how much you can stake per hand or spin while the bonus is active: $5 and $10 caps are common. Exceed the cap and the operator can void the bonus and any winnings it produced. This clause exists to stop bonus hunters from making large, low-risk wagers; for everyone else it’s a tripwire, and it’s the reason a high-roller’s normal bet size can quietly forfeit a bonus.
Expiry
Bonuses expire, commonly within 7 to 30 days of being credited. Whatever hasn’t been wagered by the deadline, bonus and winnings, is usually removed. If you can’t realistically clear the requirement inside the window, the offer’s true size is smaller than its headline.
Max cashout
Some bonuses cap how much you can withdraw from bonus winnings. This is most common on no-deposit offers, where the cap might be a few hundred dollars or a multiple of the bonus, but deposit bonuses sometimes carry caps too. A cap means the upside is finite even when your luck isn’t, check it before you plan around a big win.
Eligible games and payment methods
Two more filters worth checking: which games count at all (see weighting above), and which deposit methods qualify. Some payment options are excluded from bonus eligibility entirely, and a deposit through an excluded method can leave you with no bonus and no recourse.
The significant-terms summary
In regulated markets, operators must display a short summary of the key terms next to the offer. Treat it as a table of contents, then verify each line against the full terms. If the summary and the full terms disagree, believe the full terms, that’s the document you accepted.
Cashable vs sticky: what happens when you finish
The structure of a bonus determines what’s left in your account at the end.
- Cashable. Once the wagering requirement is met, the remaining bonus converts to real, withdrawable cash. The straightforward kind: you can see the finish line from the start.
- Sticky. The bonus never converts. It stays in your balance while you play, but it is removed when you withdraw, so only the winnings are paid out. Read the clause carefully: some sticky bonuses also cap those winnings, which turns “sticky” into “mostly decorative.”
Which is better? It depends on the numbers. A sticky bonus with a low multiplier and no cashout cap can beat a cashable bonus with a punishing one, but only if you’ve understood what leaves the account at the end. Free spins are a third structure with their own rules: spin winnings are often capped and carry a separate wagering requirement, so read them as a small standalone offer, not as a headline bonus.
What a bonus is actually worth
One multiplication and one subtraction will price almost any offer:
bonus value ≈ bonus amount − (total wagering × house edge of the games you’ll play)
Run it on our example. A $100 bonus at 35x means $3,500 wagered. On slots that return about 96 percent to players, the house edge is roughly 4 percent, so expected losses during clearing are about $140, more than the bonus itself. On average, that offer costs the player money before you count the hours.
Change the terms and the sign flips. A $100 bonus at 25x means $2,500 wagered; at a 97 percent RTP (a 3 percent edge), expected losses are about $75, less than the bonus. Same headline, different offer, because the terms changed.
Run both columns side by side and the ranking usually flips:
| Offer | Bonus | What you must wager | Expected cost at a 4% house edge |
|---|---|---|---|
| 200% up to $200, wagering 40x bonus-only | $200 | $8,000 | about $320 |
| 100% up to $100, wagering 20x bonus-only | $100 | $2,000 | about $80 |
The bigger headline carries the bigger bill: the 40x offer costs roughly $320 in expected losses to release $200, while the 20x offer costs roughly $80 to release $100.
Two honest caveats. First, averages are averages: a single session can land anywhere, and the variance on bonus clearing is wide. Second, clearing quickly means making more bets per hour, and the edge applies to every one of them: speed is not a strategy. The point of the arithmetic isn’t to predict your session; it’s to rank offers before you opt in. Our explainer on RTP covers the underlying math.
Why the terms look the way they do
Bonus programs are marketing spend, and the terms are how that spend gets budgeted. An operator can hand out bonus credits freely because those credits can only leave the building through play: every bet the bonus generates earns the house its normal edge. The multiplier, the weighting, and the caps exist to keep that arithmetic tilted the operator’s way, set so that the average player’s wagering covers the cost of the bonus. That’s why generous multipliers rarely come attached to huge bonuses, and why the occasional “no wagering” offer is usually small or spin-based. The economics have to balance somewhere, and the terms are where they balance.
A two-minute reading routine
Before you opt in to any bonus, find these six lines:
- The wagering multiplier and its base (bonus-only or deposit plus bonus).
- The game weighting table.
- The max-bet rule while wagering.
- The expiry window.
- The maximum cashout, if any.
- Eligible deposit methods and excluded games.
If any line is missing or unintelligible, don’t opt in, or ask support, in writing, and keep the answer. Compare offers side by side using the bonus terms summarized in our casino reviews, and browse the casino directory if you’re still choosing an operator.
The short version
The best bonus isn’t the biggest one; it’s the one you’d still take after reading the terms. Treat the headline as advertising and the terms as the actual offer, run the multiplication and subtraction once per offer, and skip any bonus whose rules you can’t state in a single sentence. A bonus you understand is worth more than a bonus you don’t, even when the second one has a bigger number on it.
