The headline is marketing
Every welcome offer leads with one big, friendly number: "200% up to $500 plus 200 free spins." That line is written by a marketing team, and its only job is to get you to click. It tells you the most the casino is willing to hand over. It tells you nothing about what you have to do to keep any of it, or whether keeping it is even realistic.
So train yourself to treat the headline as a starting point, not a verdict. The moment you see a match percentage, your next move is to scroll to the terms and conditions, because that is where the offer is actually defined. Two bonuses advertising the exact same "100% up to $200" can be worlds apart once you read the five terms below. Get in the habit of judging an offer by those terms and the headline stops being able to mislead you.
Wagering / rollover explained
Wagering, also called rollover or playthrough, is the single most important term in any bonus. It is written as a multiple, like 30x or 40x, and it tells you how many times you must stake the bonus before you can withdraw anything won with it. The multiple is not money you lose; it is money you have to cycle through the games.
Say you claim a $50 bonus with 35x wagering. That means 50 × 35 = $1,750 in total bets must be placed before the balance becomes withdrawable cash. You do not need $1,750; you need to place that much in stakes over many spins, winning some back and betting it again as you go. The lower the multiple, the less you have to churn, and the better the offer. As a rough guide, anything at or under 30x is generous, 35x to 40x is the modern norm, and much above 45x starts to make an offer hard to beat in practice.
Wagering base: bonus vs bonus+deposit
Here is the detail that catches out even experienced players. A wagering multiple has to be applied to something, and there are two common bases. The player-friendly version applies the multiple to the bonus alone. The tougher version applies it to your bonus plus your deposit, and the same headline multiple then means roughly double the work.
Take a $100 deposit with a 100% match, giving you $100 of bonus funds. At 35x on the bonus only, you wager $100 × 35 = $3,500. At 35x on deposit plus bonus, the base is $200 and you wager $200 × 35 = $7,000. Identical "35x" on the banner, twice the playthrough. Because the difference is invisible in the headline, you have to find the phrase that says whether the rollover applies to "bonus" or to "deposit + bonus". Always locate that line before you decide a multiple is reasonable.
Game weighting
Not every game chips away at your wagering at the same rate. Game weighting, sometimes called game contribution, sets how much each category counts toward the total. Slots almost always count 100%: bet $1, and a full $1 comes off your requirement. Table games count for much less because their house edge is thinner, so a game the casino makes little from cannot be allowed to clear a bonus quickly.
Typical contributions look like this: slots 100%, roulette 10% to 20%, blackjack and video poker 5% to 10%, and some titles excluded entirely. A 10% weighting means only a tenth of each bet counts, so clearing a bonus on roulette takes ten times the stakes it would on slots. This is why nearly every bonus is designed to be cleared on slots. Before you start, read the weighting table and check that the games you actually enjoy contribute enough to make the offer worth taking. Playing an excluded game can also void the bonus outright, so the list matters twice over.
Max bet cap
The max-bet cap is the quiet term that breaks more bonuses than any other, and it is the one players forget. It sets the largest single stake you are allowed to place while a bonus is active, usually somewhere around $4 to $5. The rule exists to stop you clearing a big requirement in a handful of high-stakes spins.
The danger is not the limit itself but how easy it is to breach by accident. You work through most of the wagering, forget the cap is still in force, nudge your stake up on a single spin, and under the standard terms the operator can void the entire bonus and everything you won with it. There is no partial penalty; one oversized bet can wipe the lot. Treat the cap as a hard ceiling on every spin until the wagering is fully completed and confirmed in your account, not as a guideline.
Expiry windows
A bonus is not open-ended. The expiry window is the deadline by which the whole wagering requirement must be met, and once it passes the bonus and any winnings tied to it simply vanish. Windows have shortened in recent years: where a comfortable 30 days was once standard, 7 to 14 days is now common, and a few offers give you less.
The window matters because it turns an abstract playthrough figure into a real demand on your time. A $7,000 rollover is very different over 30 days than over 7. Before you opt in, do the honest maths: divide the total playthrough by the number of days and ask whether your normal sessions can realistically cover it without you chasing the clock. If the only way to beat the deadline is to play far more, or far bigger, than you planned, the offer is not the bargain it looks like, however low the multiple.
A worked example
Put the five terms together and you can size up any offer in about a minute. Imagine two casinos both advertising "100% up to $200". You deposit $100 and receive $100 in bonus at each. On the surface they are identical. Read the terms and they are not.
Casino A runs 30x on the bonus only, with a $5 max bet, slots at 100%, and a 30-day window: that is $3,000 of slot play spread across a month, which is very beatable. Casino B runs 45x on deposit plus bonus, with a $2 max bet, slots at 50%, and a 7-day window: the base is $200, so 45x is $9,000 of wagering, the 50% slot weighting effectively doubles that to $18,000 of stakes, and you have a single week to do it under a tight bet cap. Same headline, wildly different reality. The table below shows where each term sits on the scale from player-friendly to best avoided.
| Term | Player-friendly | Standard | Avoid |
|---|---|---|---|
| Wagering multiple | 25x or lower | 35x-40x | 50x or higher |
| Wagering base | Bonus only | Bonus only | Deposit + bonus |
| Slots weighting | 100% | 100% | 50% or excluded |
| Max bet cap | $5 or higher | $4-$5 | Under $3 |
| Expiry window | 30 days | 14 days | 7 days or fewer |
To turn the terms into a single hard number rather than eyeballing them, drop the multiple, the base and your deposit into our bonus wagering calculator. It returns the exact total you would have to stake, which is the only figure that lets you compare two offers on equal footing. Judge bonuses by that number and by the five terms behind it, never by the size of the banner, and you will consistently pick the offers that are genuinely worth your deposit.
FAQ
What does 35x wagering actually mean?
It means you must place total bets worth 35 times the amount the multiple applies to before your bonus winnings become withdrawable. On a $50 bonus with 35x wagering on the bonus, that is 50 × 35 = $1,750 in stakes. You are not losing that money; you are cycling it through the games, and the lower the multiple the less you have to churn.
Why do table games barely count toward wagering?
Because their house edge is much thinner than a slot's. Game weighting typically counts slots at 100% but blackjack, roulette and video poker at 5% to 20%, so only a fraction of each bet clears the requirement. Some titles are excluded entirely, and playing an excluded game can void the bonus. Always read the weighting table before you choose what to play.
What happens if I bet over the max-bet cap?
Under the standard terms, breaching the max-bet cap even once while a bonus is active lets the operator void the bonus and any winnings attached to it. There is usually no partial penalty, so a single oversized spin can cost you an otherwise cleared balance. Keep every stake under the cap until the wagering is fully completed and confirmed.
How do I compare two bonuses fairly?
Ignore the headline match and work out the real playthrough. Take the multiple, the base it applies to, the slot weighting and your deposit, then calculate the total you would have to stake and check it fits inside the expiry window. Our bonus wagering calculator does the arithmetic in seconds so you can line two offers up on the one number that decides which is better value.
