About this Slot
Zombie Bonkers is a horror-themed slot from Blueberry Games with an RTP of 96%, high volatility and a maximum win of 6,000x. The game features cascading reels and pays anywhere on the grid.
Wild zombie hands substitute for regular paying symbols to complete multiple winning combinations within a single tumble. They do not replace scatter symbols or multipliers.
Scatter tombstones trigger the Free Spins round when three or more land. Three scatters award 6 free spins, with the number of spins scaling upwards based on how many scatters triggered the feature. During Free Spins, landing two or more scatters retriggers additional spins.
The Radioactive multiplier behaves differently across game modes. In the base game, it acts as a numberless collector symbol. During Free Spins, it displays numbered values of 2x, 4x, 5x, 7x, 10x, 15x or 20x. A global multiplier increases after each tumble throughout the Free Spins round, and all remaining multiplier values combine into a single board multiplier.
The Battery Bonus activates when four Radioactive multiplier collectors charge in a single tumble. This bonus awards a session multiplier of 1x, 1.5x or 2x, but only if the triggering spin produces a positive win.
Two bonus buy options are available. The Bonus costs 250x the bet, while the Super Bonus costs 500x the bet.
