A variety of viruses make up the game’s symbols, with the ultimate aim for players to defeat the zombie virus.

Multiplier wilds can also appear which are not removed in cascading wins, formed by clusters of eight. These multipliers increase in value incrementally with each tumble, while landing five scatter symbols triggers the free spins round.

Prior to this round, players can choose two icons which will not appear in any of the free spins.

R. Franco Digital said the cascading reels mechanic in Z is new to its portfolio.

The company’s international business director, Javier Sacristán Franco, said: “Z plunges players into a high-stakes science lab where they must find a cure for a deadly zombie virus.

“This game introduces cascading reels to our portfolio, reinforcing our dedication to continuously expanding our content with new mechanics that players truly enjoy.”
