Sparky & Shortz is a five-reel video slot machine with ten fixed paylines.
The Wild symbol substitutes for all symbols (except the Power Cell Scatter) and can appear on all reels.
Three identical symbols on one reel become a stack, increasing the Win Multiplier by +1. The Win Multiplier is displayed on Shortz’s body. Winning combinations are multiplied by the displayed value. The Win Multiplier resets between spins, except during Free Spins.
On every spin, Sparky tries to activate the Boost Meter. If the Boost Meter is active, each stacked reel increases the Win Multiplier by the value of the Boost Meter.
Power Cell Scatters can appear on reels one, three and five. Three Power Cell Scatters trigger 10 Free Spins. The Boost Meter is always active during Free Spins. The Win Multiplier is not reset between spins during Free Spins. Landing three Power Cell Scatters adds five more Free Spins. Free Spins are capped at 100 spins
