How the machine works

  1. Scatters award 10, 15 or 20 free spins.
  2. During them, a fisherman wild collects every fish's cash value.
  3. Every fourth fisherman adds 10 spins and raises the multiplier: 2x, 3x, then 10x.

In play

The base game is plain: ten lines, fish with cash values that do nothing until free spins. Everything turns on the feature, where each fisherman scoops up every value in view. Most features end after the first ten spins; the memorable ones retrigger two or three times and reach the 10x multiplier.

Who it suits

Players who like one clear goal and can sit through a quiet base game. It spawned a long series of sequels, so check you have opened the original.
