Compare casino promos and free bets on one page
Casino welcome offers and bookmaker free bets are scored differently on BonusRated — one on what you can withdraw after wagering, the other on how much of a free bet token converts to cash — but they compete for the same tenner. This page puts the best-rated of each side by side so you can see what your first deposit buys at a casino, a bingo site or a bookmaker.

Casino bonus or free bet: how they differ
- What you receive. A casino offer gives spins or bonus funds you play with; a free bet gives a token you stake once. Spin winnings and cleared bonus funds are yours; a free bet’s stake is not returned, so a £30 token at evens returns £30, not £60.
- What can go wrong. Casino bonuses fail on wagering and max cashout. Free bets fail on minimum odds (you’re forced to take a real risk on the qualifying bet) and expiry (5–7 days is typical). Neither has hidden traps at the UKGC-licensed sites listed here; both have arithmetic worth doing.
- Typical value. Our modelling puts a £30 free bet at £18–21 of withdrawable cash. A no-wagering spins offer is worth its spin value in expectation (100 spins at 10p ≈ £10 at 96% RTP, before the cap), which is why the casino side of this table rates higher per pound.
- Which suits a first deposit. If you’ll place one bet on the football and leave, take the free bet. If you’ll play for an hour, the casino side gives more for the same £10 and pays winnings as cash at every no-wagering site above.
The picks by situation
Best all-round first deposit — bet365 Casino. Up to 500 no-wagering spins for £10, claimed daily over ten days. The most play for a tenner in the UK, from the most established operator on the page.
Best if you want real upside — Grosvenor or The Vic. £40 plus 100 spins, or £20, for a £20 deposit, with a £2,000 cap. The bonuses are small; the ceiling is the highest we’ve verified. Same group.
Best free bet — bet365. Bet £10 Get £30 with 1/5 minimum odds and singles allowed; the only bookmaker offer we rate 4/5. Code 365GMBLR is optional.
Best if you want it done tonight — PlayOJO, Betway, Betfred Games. No-wagering spins for a £10 deposit; winnings are cash when the reels stop.
