How does the base game work?
Each spin changes how many symbols each reel shows, giving up to 147,456 ways to win. Wins tumble away and new symbols drop in. Mystery symbols turn into a matching paying symbol, and fish money symbols are worth 2x to 5,000x your bet.
How do the free spins work?
Three, four, five or six scatters award 10, 15, 20 or 25 free spins. The fisherman wild collects every fish money value on screen. Every fourth fisherman adds 10 more spins and lifts the multiplier on collected fish: 2x, then 3x, then 10x, and then a further 10x with every retrigger after that, with no limit on retriggers.
How does the Hold & Spinner feature work?
Three or more coin money symbols start the feature with 3 respins. Each new coin resets the respins to 3. Diamond money symbols are worth 50x to 2,000x, and the round keeps going until the total reaches at least 20x your bet.
