Bonus guide

Understanding casino bonus types

UK operators compete for attention with welcome packages, but the label on the tin rarely tells the full story. This page explains what each common offer type actually does — no promotional claims, just the mechanics you need to read the terms intelligently.

Matched deposit bonus

The operator adds bonus credit equal to a percentage of your first deposit — typically 100% up to a stated cap. That credit sits in a separate bonus balance until you meet wagering requirements. It is not withdrawable cash on day one.

Free spins

Spins credited on named slot titles, either with no deposit required or bundled with a first deposit. Winnings from free spins usually convert to bonus funds subject to wagering, not straight to your cash balance. Check which games qualify — spins on one slot cannot be used elsewhere.

No-deposit offers

A small number of spins or bonus credit granted before you fund the account. Useful for testing the lobby, but wagering requirements and maximum withdrawal caps on no-deposit winnings are often stricter than on deposit-match offers.

Cashback

A percentage of net losses returned over a set period — daily, weekly or monthly. Cashback may arrive as bonus funds or real money depending on the promotion. Always check whether returned funds carry their own wagering conditions.

Wagering requirements

The multiplier that determines how much you must bet before bonus winnings become withdrawable. A £50 bonus with 35x wagering means £1,750 in total bets on eligible games before cashing out bonus-derived winnings. Different games contribute at different rates — slots often count 100%, while live blackjack might contribute 10% or be excluded entirely.

How we list offers on Slot List Ledger

Operator cards state offer types factually with an “Ad · 18+ · T&Cs apply” note. We do not rank sites by bonus size because a larger headline figure with heavy wagering is often less valuable than a modest offer with fair terms.
