Rotten Potato is set in a harvest that has gone bad, with an infection spreading across a 5x4 grid.

14 SuperSpinners sit between the reels. If a win line crosses a numbered SuperSpinner, that number multiplies the win, and several spinners on the same line multiply it one after another.

Before wins are counted, one of two Mystery Features can trigger. Potato Horde covers an area from 2x2 up to 5x4 with Mystery Symbols, and Spreading Fungus covers 4 to 20 random positions. All Mystery Symbols then turn into the same paying symbol.

Three, four or five Scatters trigger the Potato Plague Bonus with 10, 12 or 14 free spins. A 1x2 Rotten Potato Wild locks onto the middle reel. When it is part of a win, every position in that win becomes infected for the rest of the round and acts as a Mystery Symbol. Random infections can also strike after any spin, and with 5 Scatters they are guaranteed every spin. A meter moves through 5 infection stages, and each new stage adds extra spins and bigger SuperSpinner multipliers.
