Ice Luck implements a cascading symbol mechanic where winning combinations trigger ice crystal shatters, causing symbols above to drop into empty positions. Each consecutive cascade increases the multiplier by 1x, capping at 8x during base gameplay. The avalanche continues until no new winning combinations form on the 5x3 grid.
The polar bear wild symbol appears on reels 2, 3, and 4, substituting for all standard symbols except the scatter. When part of a winning combination, polar bear wilds apply a random multiplier between 2x and 5x to that specific win. The glacier bonus scatter requires three symbols anywhere on the reels to trigger the free spins feature with 10 initial spins.
During the glacier bonus round, the multiplier baseline shifts from 1x to 2x, meaning the first cascade starts at 2x instead of 1x, and the maximum cascade multiplier extends to 15x. Additional scatters appearing during free spins award +3 spins per scatter, with no upper limit on retriggers. The progressive jackpot seeds at $1,000 and increments with each qualifying spin across the network.
