Our testing showed Tombstone RIP (extreme volatility) depleting a £20 balance in 160 spins, while The Goonies (low volatility) lasted all 250 spins with money left. A 20-minute session at 20p per spin covers roughly 200 spins and costs around £40 in total bets. Recognising this pattern before you start playing is more useful than any responsible gambling tool, though those tools exist for good reason.

Uncomplicated in the base game, just the usual wilds and scatters. It’s a simple 5-reel, 12-payline slot. Reel it in with Bigger Bass Splash, a slot in one of Pragmatic Play’s biggest franchises. The Jam Jar symbol doubles up as wild and scatter, and it comes with its own multiplier that climbs every time it’s part of a win. Land 5 or more matching symbols touching each other and they clear from the reels, cascading in new ones for a shot at another win straight away.
