Z is a unique slot game developed by R Franco that features a captivating theme centered around various types of bacteria. The game is played on an unconventional 5×7 hexagonal grid, adding an interesting visual twist to the gameplay.
The slot incorporates the popular Cluster Pays mechanic, where winning combinations are formed by landing 8 or more identical symbols in adjacent positions. After each win, the winning symbols disappear, and new ones cascade down to fill the empty spaces, potentially creating additional winning clusters.
Wild symbols play a crucial role in Z, as they substitute for all other symbols to form the best possible winning combinations. They also come with an initial multiplier of x2, which increases by 1 for each cascade involving a Wild symbol. If multiple Wild symbols contribute to a cluster, their multipliers are added together, leading to potentially massive payouts.
The game also features a Free Spins round, triggered by landing 5 or more Scatter symbols anywhere on the reels. The number of free spins awarded is determined by the sum of the values shown on the Scatter symbols (2, 3, or 5). Before the Free Spins begin, players must choose to discard either the 2 highest or 2 lowest value symbols, which will not appear during the bonus round.
