How Welcome Bonuses Work
Welcome bonuses typically come in two forms: matched deposits and free spins. A matched deposit bonus means the casino matches your first deposit (or a series of deposits) up to a certain amount. For example, "100% up to £100" means if you deposit £100, you receive £100 in bonus funds — £200 total to play with. Deposit £50 and you get £50 bonus; deposit £200 and the bonus is capped at £100.
Free spins are usually credited either instantly upon qualifying deposit or in batches over several days. They are typically valid on specific slot games chosen by the casino. Winnings from free spins may be subject to wagering requirements before they can be withdrawn.
How bonuses are credited varies by operator. Some add bonus funds to a separate balance; others credit them to your main account with play-through restrictions. Always read the promotion terms to understand exactly when and how your bonus is applied.
Wagering Requirements Explained
Wagering requirements (also called play-through or rollover) are the number of times you must bet your bonus (and sometimes your deposit) before winnings can be withdrawn. A 35x requirement on a £50 bonus means you must place £1,750 in total bets. This sounds steep, but it is standard in the industry — some casinos impose 40x, 50x, or higher.
Contribution rates matter. Slots often contribute 100% toward wagering, but table games may contribute 10%, 5%, or nothing at all. Some games are excluded entirely. A £10 bet on blackjack with 10% contribution only counts as £1 toward the requirement. Always check which games count and at what rate.
Game restrictions can make a seemingly fair bonus much harder to complete. If your favourite games contribute little or nothing, the effective wagering burden increases. We highlight these details in our bonus comparisons so you can choose offers that suit how you play.
Free Spins: What to Expect
Free spins work like regular spins on a slot, but you do not pay for them. The casino credits a set number (e.g. 20, 50, 100) to your account, usually on a specific game. Value per spin depends on the game's minimum bet — if the slot has a 10p minimum, each spin is worth 10p; if it is 20p, each spin is worth 20p. A "20 free spins at 10p" package has a theoretical value of £2.
Winnings caps are common. Some casinos cap free-spin winnings at £10, £50, or £100. Anything above that may be forfeited or converted to bonus funds with additional wagering. Expiry is another key term: free spins often must be used within 24–72 hours, and any resulting bonus balance may expire within 7–30 days.
Not all free spins are equal. Some are "no wagering" — winnings go straight to your real balance. Others carry 35x or higher requirements. We always note the wagering terms and any caps so you know what you are really getting.
Bonus Terms to Watch Out For
Max bet limits are frequently overlooked. Many bonuses restrict you to £5 or less per spin while wagering. Exceed the limit and the casino may void your bonus and any winnings. Game exclusions are equally important — if the bonus only applies to a handful of slots you do not enjoy, it may not be worth claiming.
Time limits apply to both claiming and completing the bonus. You may have 7–14 days to opt in after your first deposit, and then 7–30 days to meet the wagering requirements. Miss the deadline and the bonus and associated winnings can be removed. Withdrawal caps are another trap: some casinos limit how much you can withdraw from bonus winnings, even after wagering is complete.
Read the full terms before you deposit. The headline offer is marketing; the small print determines whether the bonus is fair and achievable. We flag restrictive terms in our reviews so you can avoid unpleasant surprises.
Our Approach to Bonus Ratings
We do not rate bonuses solely on headline figures. A "£1000 bonus" with 50x wagering is often worse value than a "£100 bonus" with 30x wagering. We evaluate the full offer: wagering requirements, contribution rates, game restrictions, time limits, and max bet caps. Fairness of terms matters as much as the advertised amount.
Transparency is central to our approach. We explain how each bonus works in plain language and highlight any terms that could disadvantage players. We prefer bonuses with clear, achievable conditions over those that look generous but are hard to convert into real cash.
Our bonus ratings reflect the overall value and fairness of the offer, not just its size. We recommend bonuses from operators we trust and that we believe offer a genuine benefit to players who understand and accept the terms.
