You must land between three and five icons on consecutive reels. In addition, this game features symbols that disappear. After a victory, they vanish and are replaced by fresh ones. Using any device, players select a wager between 0.20 and 40 to proceed with the task of surviving. Regular play of Zombie aPOPalypse MultiPop results in an RTP of 96.0%, despite the game's significant volatility. Some players may have the option of purchasing free spins, however it is not specified whether or not this impacts the RTP. An additional method of play involves enabling the ante bet type option, which increases the wager by 25 percent and doubles the probability of triggering free spins.
Symbols pay for three to five of a kind and are categorised as Q-A lows, hair (yep, hair), footballs, and hats as mediums, and five-character symbols as highs. Five-of-a-kind victories are paid 0.4x the wager for royals, 0.5x the wager for middle cards, and 0.75 to 2x the wager for high cards. Notably, five-of-a-kind wins only pay in one direction, not both.
In addition, the MultiPop function adds a +x1 multiplier to the places that held the winning symbols. This multiplier is associated with each individual cell and not with the symbol. If wins occur in cells containing multipliers, the values increase by one, up to a maximum of five times the basic value in the main game. Multipliers reset between paid game spins.
If a cell's multiplier reaches x5, Infectious Multipliers is activated. Here, between 4 and 12 random spots have their multipliers enhanced by +1. Emphasis is placed on cells that lack a multiplier.
In the base game, 3, 4, or 5 stray symbols trigger 10, 12, or 15 free spins, respectively. Afterwards, players are given the option to bet up to 20 of their free spins or collect and go to the bonus round. During free spins, the grid size rises to 5x5, and there are 6,250 possibilities to win (including the pay both ways element). Moreover, individual cell multipliers are no longer reset between free spins and can now reach a maximum of x10. If every cell in the grid receives a multiplier, +2 extra free spins are granted.
