Best New Casino Sites for Existing Customers – 2026

PlayOJO is the one I would use for regular play rather than offer chasing. If you want the biggest batch of spins for £10, BetMGM is the better pick, with 200 wager-free spins. OJOplus then pays cash back on every bet from your first spin onward, with no wagering attached either. The spins expire after 7 days, and the offer can’t be combined with any other.

Betting Sites

Opt in, deposit and stake £10 on any slot, and you get 50 free spins on Big Bass Splash at 10p each. Slots highlights include Big Bass Splash, the welcome spins game, plus Big Bad Wolf from Quickspin, Starburst XXXtreme from NetEnt non gamstop casinos and Rise of Olympus from Play’n GO. Stake £10 on any slot and the 50 spins carry no wagering, so whatever they win is cash.

For example, a site that performs steadily across all scoring metrics will likely be deemed better than a brand that goes hard on bonuses but neglects other areas.
