Comparing bonuses in October 2026
The headline on a bonus card tells you the largest amount you could receive. It does not tell you what the offer is worth. Two offers with the same headline can differ by hundreds of pounds or dollars in real value once wagering, game weighting, maximum bets and caps on winnings are applied. This guide sets out how to compare the offers in the listing above using the same arithmetic we use in our reviews.
The market has also changed. Britain capped wagering in January 2026, most large crypto casinos now lead with rakeback rather than a big match, and the US books compete on bet-and-get offers that work very differently from casino bonuses. A single “best bonus” does not exist: the right offer depends on where you live, what you play and how much you plan to stake anyway. For the full background on terms, read our casino bonuses explained guide.
Wagering maths in one table
Wagering is the amount you must stake before bonus money, or winnings from it, can be withdrawn. Every bet you place to clear it has an expected cost equal to the house edge. On a slot with 96% RTP, the expected cost is about 4% of everything you stake. That single number lets you compare almost any offer.
| Offer on a 100 deposit | Total to wager | Expected cost at 96% RTP | Expected value of the bonus |
|---|---|---|---|
| 100 bonus at 10x the bonus | 1,000 | 40 | about +60 |
| 100 bonus at 35x the bonus | 3,500 | 140 | about −40 |
| 100 bonus at 40x deposit plus bonus | 8,000 | 320 | about −220 |
Take the 35x offer. You must stake 100 × 35 = 3,500. At a 4% house edge the expected loss over that play is 3,500 × 0.04 = 140, which is more than the 100 bonus. On average you finish worse off than if you had played the deposit alone, although some players will still get lucky. At 10x the expected loss is 40, so the bonus keeps about 60 of its value.
Two cautions apply. First, these are averages: variance means most players either bust the balance early or finish well above or below the expected figure. Second, the RTP of the games you are allowed to play matters. If the terms restrict you to lower-RTP slots, or table games count at 10%, the real cost of wagering rises sharply.
The UK 10x cap and other rules by market
Since 19 January 2026, operators licensed by the UK Gambling Commission cannot set wagering above 10 times the bonus amount, and they cannot run promotions that require you to gamble on two or more products, such as a sports bet that unlocks casino spins. The Commission considered a full ban and caps of 1x or 5x before settling on 10x. That is why offers from brands such as 888 and bet365 look different in Britain from elsewhere. Our Great Britain page covers the wider rule changes.
Other markets set their own rules. US sportsbooks mostly offer bonus bets or “second chance” bets, where the bonus stake is not returned with any winnings, and casino matches vary by state. Ontario sets its own advertising limits. Offshore crypto casinos are not covered by any of these caps, so a 40x or 60x requirement is still possible there. Always read the terms that apply to your account, not a figure from another country.
Match bonus, rakeback or cashback
Most offers fall into one of three types. They suit different players.
| Type | How it pays | Suits |
|---|---|---|
| Deposit match | Bonus money added on deposit, locked until wagering is met | Players who will stake the required amount anyway and accept the restrictions |
| Rakeback | A share of the house edge on every bet, paid win or lose | Regular players who want no wagering and no maximum bet rules |
| Cashback | A share of net losses over a period | Players who want a cushion on losing weeks |
Rakeback is easy to overvalue. It is usually calculated on the house edge, not on your stake. If you wager 5,000 on slots with a 4% edge, the expected loss is 200. Ten per cent rakeback returns about 20, so a “10% rakeback” is worth about 0.4% of turnover. That is real value with no strings, but it is small. Our rakeback casinos guide explains the different formulas operators use. Brands that lead with rakeback rather than a match include Shuffle, Gamdom and Goated; check each review for the current terms.
How crypto bonuses are structured
Crypto casinos have developed a few structures of their own. None is better in principle, but each changes how you should value the headline.
- Multi-deposit packages. The headline adds up three or four separate deposit matches, as with BC.Game and mBit. Only the first is likely to matter to most players, so value that one on its own.
- Locked or drip-released bonuses. The bonus sits in a separate balance and unlocks in small increments as you wager, as with the locked bonus at Whale.io. You keep what you have released even if you stop.
- Level-up and VIP rewards. Cash or spins paid as you climb tiers. These are a form of rakeback paid in lumps.
- Token rewards. Some casinos pay rewards in their own token. Its price can fall before you sell, so treat the value as uncertain.
- No-deposit offers. Small, heavily capped and often restricted to one game. Our no-deposit bonus guide covers what they are realistically worth.
Bonuses are usually quoted in dollars or euros but paid in crypto. If the coin’s price moves during wagering, the value moves with it. Stablecoins avoid that; our USDT casinos guide explains how.
Red flags in bonus terms
These terms do not always make an offer bad, but each should make you stop and do the sums again.
- Wagering applied to deposit plus bonus rather than the bonus alone.
- A low maximum bet during wagering, with winnings confiscated if you exceed it even once.
- A cap on winnings from the bonus, sometimes as low as 5 or 10 times the bonus.
- Short expiry, such as seven days to clear 35x.
- Vague “irregular play” clauses that let the operator void winnings at its discretion.
- Bonuses applied automatically on deposit with no way to decline them.
- Terms that differ between the promotion page and the general bonus policy.
If the terms are hard to find, contradict each other or allow the casino to cancel winnings without a stated reason, skip the offer. A bonus is never worth a withdrawal dispute.
A quick comparison checklist
Run each offer in the listing through these steps before claiming it:
- Check the operator is licensed for your country on our coverage page or the relevant country guide.
- Find the wagering multiple and what it applies to.
- Multiply the amount to wager by the house edge of the games you will play.
- Compare that cost with the bonus. If the cost is higher, the bonus has negative value on average.
- Note the maximum bet, game weighting, expiry and any cap on winnings.
- Decide whether you would be better off declining the bonus and taking rakeback or cashback instead.
Free spins and slot-specific offers have their own maths; see our game bonuses page. Whatever you claim, a bonus should not change how much you planned to spend. Set limits first and read our responsible gambling guide.
