Casino bonuses look generous on the landing page, but the real story is in the wagering requirements buried in the terms and conditions. Understanding those terms is the difference between claiming a useful offer and locking up your money on a bonus you can't realistically clear.
This guide breaks down wagering in plain English: what numbers like 35x actually mean, how game weighting changes the maths, and a simple way to estimate the real value of any bonus before you deposit.
What Wagering Requirements Actually Are
A wagering requirement (sometimes called a playthrough or rollover) is the total amount you must bet before bonus funds, and any winnings from them, can be withdrawn as cash. It's expressed as a multiplier, such as 30x or 40x.
The key question to ask is: 30x of what? Casinos generally apply wagering in one of three ways, and the difference matters a lot.
Bonus-only wagering
The multiplier applies only to the bonus amount. If you receive a $100 bonus with 35x wagering, you must wager $100 × 35 = $3,500 in total bets before the bonus converts to withdrawable cash.
Deposit + bonus wagering
The multiplier applies to your deposit plus the bonus. With a $100 deposit and a $100 bonus at 35x, you'd need to wager ($100 + $100) × 35 = $7,000. That's twice the playthrough of a bonus-only offer with the same headline number.
Deposit-only wagering
Less common, but typically the most player-friendly. The multiplier applies to your deposit alone.
Always check the terms to see which model applies. A 25x deposit+bonus requirement can be tougher than a 40x bonus-only one.
Game Weighting: Not All Bets Count Equally
Almost every casino applies game weighting to wagering contributions. This means $1 wagered on one game doesn't always count as $1 toward clearing the bonus.
Typical weightings you'll see in the terms include:
- Slots: usually 100% (every $1 bet counts as $1 toward wagering).
- Table games like blackjack and baccarat: often 5-20%, sometimes 0%.
- Roulette: commonly 10-50%, or excluded entirely.
- Video poker: often 10-20%.
- Live dealer games: frequently reduced or excluded.
Example: you have a 35x bonus of $100, so $3,500 of wagering is required. If blackjack counts at 10%, you'd need to bet $35,000 on blackjack to clear it, not $3,500. That's why slots are the usual route for clearing bonuses, even if you prefer table games.
Other Rules That Quietly Change the Maths
Wagering multipliers are only part of the picture. These additional terms often decide whether a bonus is actually clearable.
Maximum bet while wagering
Most casinos cap your bet size while a bonus is active, often around $5 per spin or hand. Exceeding it, even once, can void the bonus and any winnings. Always check the cap before you start playing.
Time limits
Bonuses typically expire after a set period, such as 7, 14 or 30 days. If you don't complete the wagering in time, the bonus and associated winnings are usually forfeited.
Maximum cashout
No-deposit and free-spin bonuses often cap how much you can withdraw from your winnings, for example, a maximum of $50 or $100 regardless of how much you actually win. This dramatically affects a bonus's real value.
Restricted games and strategies
Some games are excluded entirely. Hedging strategies (such as covering most of the roulette table) and certain low-risk bets are usually banned and can void winnings.
How to Estimate the Real Value of a Bonus
Once you understand the rules, you can roughly estimate what a bonus is worth. Here's a simple framework, keep in mind these are estimates, not guarantees of outcomes.
- Calculate total wagering required (multiplier × the relevant base amount).
- Identify the game you'll actually play and its weighting.
- Look up the game's RTP (return to player), slots commonly sit around 94-97%.
- Estimate expected loss from wagering: total wagering × (1 − RTP).
- Compare that expected loss to the bonus amount. If the bonus is larger, the offer has positive theoretical value; if smaller, it likely has negative value.
Worked example: a $100 bonus with 35x bonus-only wagering means $3,500 of slot play. On a slot with 96% RTP, expected loss is $3,500 × 0.04 = $140. On paper, the bonus ($100) is smaller than expected losses ($140), so the offer has slightly negative expected value before factoring in variance.
This is theoretical only. Real results swing widely up or down due to variance, that's the nature of gambling. The maths simply tells you whether the bonus structure is fair, generous or stacked against you.
Quick Checklist Before Claiming Any Bonus
- What's the wagering multiplier, and is it on bonus, deposit, or both?
- Which games count, and at what percentage?
- What's the maximum bet allowed while the bonus is active?
- How long do you have to complete the wagering?
- Is there a maximum cashout on winnings?
- Are your preferred games excluded or restricted?
- Can you withdraw your deposit at any time, or is it locked alongside the bonus?
If any answer is unclear, contact support before depositing. A reputable casino will explain its terms; vague or evasive answers are a red flag.
Play Responsibly
Bonuses can stretch your bankroll and give you more entertainment for your deposit, but they are not a way to make money or solve financial problems. Online gambling is for adults only (18+, or the legal age in your jurisdiction) and availability varies by region. Set a budget you're comfortable losing, use deposit and time limits where available, and step away if play stops being fun. Support is available through services such as GamCare, GambleAware and Gamblers Anonymous.
Frequently asked questions
What does 35x wagering mean?
It means you must place total bets equal to 35 times a base amount, usually the bonus, sometimes the deposit plus bonus, before bonus funds and their winnings can be withdrawn. Always check which base amount the multiplier applies to.
Why don't my blackjack bets clear the bonus as quickly as slots?
Because of game weighting. Slots typically count 100% toward wagering, while blackjack and other table games often count only 5-20%, or sometimes nothing. The same dollar wagered clears far less of the requirement on low-weighted games.
Are low wagering bonuses always better?
Usually, yes, a lower multiplier means less play to clear the bonus. But also check whether wagering applies to the bonus only or to deposit plus bonus, the max bet, time limit, and any maximum cashout. A 'low wagering' offer with a tiny cashout cap can be worse than a higher-wagering one without that cap.
Can I withdraw my deposit if I change my mind about the bonus?
It depends on the casino. Some allow you to cancel the bonus and withdraw your unspent deposit; others lock the deposit alongside the bonus until wagering is met. Check the terms before depositing, and contact support if anything is unclear.
