The five bonus types we cover

What a bonus actually costs you

A bonus is a loan you repay in wagered stakes. A 100% match up to £200 with 35x wagering means the £200 bonus has to be bet £7,000 across qualifying games before any of it is yours. On a slot with a 96% RTP, that £7,000 of turnover is expected to burn through roughly £280 of your own money, which is more than the bonus itself. The headline sells the number on top of your deposit. The receipt lives in the wagering line.

On every review we walk the bonus through its full life cycle. Deposit, claim, play through, cash out, and we write up the number that landed in our account against the number the banner promised. If the gap is cheerful, the site scores. If the terms shrink the bonus to an advert, it shows.

How we score bonus terms

Wagering sits at the centre. Anything over 40x on a slot bonus is a flag. Game weighting is next: if blackjack contributes 10% to wagering and roulette contributes 0%, say so on the banner, not in the footer. Expiry windows under seven days give the operator the house edge twice: once at the table, once on the clock. Max cash-out caps on winnings turn the whole offer into a lottery ticket, so we note the cap in the ranking.

Markets where regulators cap bonuses (UK, Sweden, Netherlands) look thin on paper but often clear faster, because the wagering is lower by law. Offshore brands advertise bigger numbers with harder terms. Both can be fair. We rank what the full ride is worth, not the number above the deposit field.

Red flags in the small print

Why the same offer looks different across markets

A 200% welcome bonus up to €500 on a Curaçao-licensed brand in France clears the way one would expect. The same brand running a UK-facing site under UKGC rules caps the headline at a 100% match, drops the max to £100, and strips the free spins. Not because the operator wants to; because the licence requires it. That is why we keep a per-market view of every bonus, not a single league table.

Frequently asked

Are casino bonuses ever actually worth claiming?

The best ones, yes. A 100% match with 25x wagering on the bonus alone, a seven-day clearing window and a reasonable max bet is solid value. The industry average sits closer to 35x on bonus+deposit and a five-day window, which is marginal. We mark the gap on every review.

Why are UK and Swedish bonuses so small compared with offshore brands?

Regulators cap them. UKGC rules cap bonus marketing on licensees, Spelinspektionen limits bonuses to a first deposit at Swedish-licensed sites, Kansspelautoriteit restricts in the Netherlands. Offshore brands are not bound by those caps, so the numbers are bigger. Whether the full offer is better is a different question.

Can I withdraw the deposit if I claim a bonus and change my mind?

At most operators, no, the bonus terms lock your deposit to the wagering cycle. A few let you void the bonus pre-wagering and withdraw. The terms page is the only place to check, and we flag operators where voiding a bonus is cleanly possible.

Do no-wagering free spins really exist?

Yes, more often now than five years ago. They are smaller offers, typically 10 to 25 spins at £0.10 to £0.50 per spin, but winnings are cash and can be withdrawn right away if the account is verified. We keep a running list on the free-spins page.

What is a fair wagering requirement?

For a slot bonus, 25x on the bonus alone is good, 30x is average, 40x+ is a flag. Live-casino bonuses are rarer because weighting usually cuts live games to 10% or 0%, meaning the stated multiple is misleading. Read the weighting table, not the big number.

Should I claim the welcome bonus or skip it?

Skip it when you want to withdraw quickly, claim it when you want long session time and know the terms. If the first thing you plan to do after depositing is cash out, do not touch the bonus; the wagering rule will trap the deposit.
