VIRUS MANIA™ plays out on six reels, where clusters of eight or more matching symbols trigger payouts and vanish from the board, causing symbols from above to cascade down and fill the gaps. This chain reaction continues as long as new winning combinations emerge. WILD symbols can substitute for all other symbols except SCATTERS, and when WILDS with multipliers join a win, they infect the multiplier value, causing it to grow.
However, non-multiplier WILDS have no effect on this value. Special virus symbols occasionally land, collecting WILD symbols outside the board. The stocked WILD icons are unleashed in the next cascade, adding another element of unpredictability and excitement. To enter FREE SPIN mode, four or more SCATTER symbols must land, unlocking a contagion of bonus spins.
