Reading Bonus Terms: The Six Lines That Matter Most
Nobody reads a full bonus terms page. Fortunately, you don’t have to. Almost everything that determines whether a bonus is worth accepting is contained in six specific terms, and once you know what to look for, checking them takes a couple of minutes.
1. Wagering requirement
Capped at 10x the bonus amount since January 2026. Confirm the multiplier applies to the bonus only (deposits cannot be locked under UK rules) and whether it also applies to free-spin winnings. Multiply bonus × wagering to get the total to stake.
2. Game contribution
The percentage of each bet that counts. Slots usually 100%; table and live games often 10% or 0%. Divide the total to stake by the contribution of the game you’ll actually play. This is now the term most likely to make a bonus impractical.
3. Maximum bet
The largest stake allowed per spin or hand while the bonus is active — commonly £2 to £5, sometimes lower. Exceeding it can void the bonus and winnings. Also check for a rule against betting more than a percentage of the bonus balance, which some sites apply.
4. Expiry
Two deadlines often apply: one for claiming or using the bonus and one for completing wagering. Seven days is tight for a large requirement; thirty is comfortable. Work out whether the required number of spins fits the window at your normal pace.
5. Maximum cashout / win cap
More common on no-deposit offers and free spins than on matched deposits, but always worth checking. A cap of £100 on a bonus with 10x wagering means the upside is limited while the wagering cost is not.
6. Excluded games
The list of titles that don’t count or can’t be played with bonus funds. If your usual games are on it, the bonus is worth little to you whatever the other terms say.
Where to find them
Most operators publish a short “key terms” summary alongside the offer, which UK advertising rules require to include the significant conditions. The full terms will have a numbered section per bonus. Search the page for “wagering”, “contribution”, “max bet”, “expire”, “cap” and “excluded” — that finds all six in under a minute.
A worked evaluation
A £50 matched bonus, 10x wagering, slots 100%, max bet £5, 30 days, no cap, ten popular slots excluded.
- Total to stake: £500
- At £1 per spin: 500 spins — fine within 30 days
- Expected cost on a 96% slot: £20
- Expected value after wagering: about £30
- Question: are any of the ten excluded slots ones I’d want to play? If not, this is a reasonable offer if I was going to deposit £50 anyway.
Same bonus, but 7 days and max bet £1: 500 spins at £1 in a week is doable but requires several sessions; the value hasn’t changed but the practicality has.
Same bonus, live casino 10%: £5,000 to stake, expected cost £50+ — worse than no bonus.
Terms that should end the conversation
Wagering on deposit as well as bonus (not permitted for UK licensees); “irregular play” clauses so vague they could cover anything; withdrawal limits that make a large win impossible to cash out. These are more common on unlicensed sites, which is another reason to check the register.
The mindset
A bonus is a product with a price. The six lines above are the price tag. If you wouldn’t buy it at that price, don’t accept it — the deposit is yours to play however you like.
Bonuses tend to prompt deposits that weren’t planned. Decide your budget first, then see whether a bonus fits it — not the other way round.
