Big Bass Bonanza UK

The slot

A fishing slot whose free spins have a fisherman collecting cash values from fish. Its default RTP is the highest of the seven.

How it plays

Scatters award 10, 15 or 20 free spins. During them every fisherman collects all fish values in view, and every fourth fisherman adds ten spins and raises the multiplier: 2x, then 3x, then 10x. Most features end before the first retrigger.

The rules for slots in Britain

Online slots are limited to £5 a spin, or £2 for ages 18 to 24. Each spin must take at least 2.5 seconds, autoplay is banned, and features that speed play up are not allowed. Buying a bonus round is not offered. A slot may not celebrate a return smaller than your stake as a win, and must show how long you have played and your net position.

Bonuses and Big Bass Bonanza: what counts

Welcome offers at UK casinos are built around slots. Free spins play on named slots, and bonus money is usually cleared on slots at full weighting, while table and live games count for little or nothing. If Big Bass Bonanza is your game and it is not a slot, a wager-free spins offer costs you nothing to take and leaves your cash free for the tables; a wagered bonus is usually best declined. Whatever you take, the legal maximum for wagering is ten times the bonus.

Keeping Big Bass Bonanza within limits

Every UK-licensed casino must offer deposit limits, reality checks, time-outs and self-exclusion, and must take part in GAMSTOP, which blocks you from all licensed sites at once. Use the deposit limit from the first day. If gambling stops being enjoyable, or you are spending more than you planned, the National Gambling Helpline is free and open around the clock on 0808 8020 133.
