A welcome bonus is a loan of playing credit with conditions attached, and the conditions are where its value is decided. The headline figure tells you almost nothing. Three other numbers, printed smaller, tell you almost everything.
The four numbers that define an offer
Every welcome bonus, whatever the branding, reduces to the same four variables. Find them and you can price any offer in about a minute.
- The match. How much credit you receive, usually as a percentage of your first deposit up to a ceiling.
- The wagering multiple. How many times the bonus, or sometimes bonus plus deposit, must be staked before it converts to withdrawable cash.
- Game weighting. How much each game type contributes toward that total.
- The cap and the clock. Maximum withdrawal from bonus winnings, and how long you have.
Wagering requirements, worked through
Suppose an offer gives you £100 at 35x wagering. The multiple applies to the bonus, so you must stake £3,500 before anything converts. That is not £3,500 of losses. It is turnover, and the same money recycles as you win and re-stake it. But it is a genuine volume of play, and at typical slot pace it is a long session.
Check whether the multiple applies to the bonus alone or to deposit plus bonus. The second version is common and roughly doubles the work. On a £100 deposit matched by £100 at 35x, bonus-only means £3,500 of turnover and deposit-plus-bonus means £7,000. The offers look identical in the advertising.
As a rough guide, anything at or below 25x is genuinely good, 30x to 35x is the industry norm, and above 40x is difficult to clear without a large bankroll and a lot of time. Those bands are our own framing rather than an industry standard, and individual terms always override them.
Game weighting is where table players lose
Weighting sets how much each pound staked counts toward the requirement. Slots typically count in full. Table games count for a fraction, and the fraction is often small.
| Game type | Typical contribution | Effect on a £3,500 requirement |
|---|---|---|
| Slots | 100% | £3,500 of play |
| Video poker | 10-20% | £17,500 to £35,000 |
| Roulette | 10% or excluded | £35,000, or the bonus is void |
| Blackjack | 10% or excluded | £35,000, or the bonus is void |
The percentages above are the common pattern rather than a rule, and each operator publishes its own table. Read it before depositing if you are a table player. A blackjack specialist claiming a slots-weighted bonus has accepted a requirement ten times larger than the one advertised, and in some cases has agreed to terms that void the bonus entirely if they play their usual game.
Excluded games are the sharper version of this problem. Placing a single bet on an excluded game can forfeit the bonus and everything won with it, and support will point at the terms you accepted. That outcome is avoidable purely by reading.
Max cashout, the quiet ceiling
Many bonuses cap what you can withdraw from bonus winnings, regardless of what you actually won. Hit a large win on bonus funds under a low cap and the excess is removed when you request payment.
On deposit-match offers the cap is often generous or absent. On no-deposit offers it is usually the defining term, and it is the reason a free bonus with a low ceiling is worth less than it appears. We would rather take a smaller offer with no cap than a larger one that quietly limits the outcome, and we rank them that way.
Expiry, and how it interacts with everything else
Bonuses expire, commonly somewhere between seven and thirty days. The expiry window and the wagering multiple have to be read together, because a high multiple on a short clock can be arithmetically unreachable at any sane stake size.
Work out the turnover, divide by the days available, and ask whether that daily volume is something you would play anyway. If the answer is no, the offer is not for you, however large the headline. Chasing a requirement against a deadline is the most reliable way we know of turning a bonus into a loss.
Sticky and non-sticky bonuses
A non-sticky bonus keeps your deposit separate from the bonus credit. You play with your own money first, and you can withdraw it at any point without touching the bonus or its conditions. A sticky bonus merges the two, so everything is locked until wagering completes.
Non-sticky is better for you, and by a wide margin. It lets you take a win and leave. Operators know this, which is why non-sticky offers usually carry smaller headline figures. That trade is generally worth taking.
How we price an offer
Our order of checks is the same every time. Multiple first, then what it applies to, then weighting for the games we actually intend to play, then the cap, then the clock. The headline comes last, because by the time we reach it we already know what the offer is worth.
Applied to two real-looking examples: £50 at 20x bonus-only, slots at 100%, no cap, thirty days is a better offer than £300 at 45x on deposit-plus-bonus with a £100 ceiling and seven days. The second is six times larger in the advertising and worth less in practice.
No-deposit offers are a different product
A no-deposit bonus gives you playing credit without funding the account first. It sounds like the best category on the page and it is usually the weakest, because everything that limits a bonus is turned up.
The amounts are small, the wagering multiple is typically higher than on deposit matches, and the maximum cashout is nearly always present and low. A common shape is a modest credit at a high multiple with a ceiling somewhere near the credit itself. Clear the wagering, win well, and the ceiling removes most of what you won.
That does not make them worthless. It makes them a way to test a casino at no cost. Use one to see how the lobby behaves, how fast support answers, and how verification is handled, then judge the operator on that rather than on the bonus outcome. Treat any withdrawal as a bonus on top.
Free spins, and the number that is missing
Free spin offers are quoted as a count, and a count on its own is not a value. Two figures decide what a spin is worth: the stake each spin is played at, and the game it is locked to. Twenty spins on a game with a high fixed stake is worth several times fifty spins pinned to a minimum-stake title.
Winnings from free spins usually arrive as bonus credit rather than cash, and that credit carries its own wagering requirement. So the sequence is: spin, convert winnings to bonus funds, then clear a multiple on those funds before any of it can leave. Offers that pay free spin winnings as cash exist and are considerably better. They advertise the fact, because it is unusual.
Check the expiry separately from the main bonus clock. Spins often expire faster than the credit they generate, sometimes within a day or two of being credited.
Reload offers and loyalty schemes
Welcome bonuses are one-off. Reload offers repeat, usually weekly or monthly, and at smaller percentages. Their terms tend to be gentler, since the operator is no longer paying to acquire you, and a modest reload at 20x can be worth more over a year than a large welcome offer taken once.
Loyalty schemes are harder to price. Points accrue against turnover and convert to credit at a published rate, and the rate is where the value sits. Work out how much play produces a pound of credit, and compare that to what the same play costs you in expected loss. In most schemes the answer is that loyalty credit is a partial rebate rather than a reward, which is fine as long as it is not treated as a reason to play more.
Tiered schemes deserve particular care, because they are designed to make the next level feel close. Progress toward a tier is not a reason to keep playing that survives contact with the arithmetic.
When a bonus goes wrong
Disputes over bonuses follow a small number of patterns: a bet placed on an excluded game, a stake above the per-spin cap that bonus terms impose, wagering completed after expiry, or a withdrawal request made before the requirement was met. Each of those is written into the terms, and each voids the bonus.
The per-spin cap catches people out most often. Many offers limit stake size while bonus funds are in play, commonly to a few pounds per spin, and exceeding it once can forfeit everything. The limit is rarely displayed in the game, only in the terms.
If an operator withholds bonus winnings and you believe the terms were met, raise it in writing with the operator first and keep the reference number. If that fails, a UKGC licensee must route the complaint to an approved ADR body, named on the site. That process is free to you and the operator is bound by the outcome. It is also the reason licensing sits at the top of our ranking criteria.
One habit is worth more than any of this analysis. Set a deposit limit before you claim anything. Bonus terms are designed to increase how much you play, and a limit is the one term in the arrangement that you get to write.
