How the Game Plays

100 Zombies transports you to a post-apocalyptic cityscape where a scientific experiment has gone dreadfully wrong. The game utilizes a larger-than-average 5x4 grid to accommodate its 100 paylines. On the reels, you will encounter a trio of brave survivors—an adventurous girl, a young hero, and a seasoned veteran—standing their ground against a horde of undead characters, including zombie nurses and mailmen. Winning combinations are formed by landing matching symbols from left to right, with the survivor symbols offering the highest payouts.

Free Spins Explained

The feature is triggered by landing three Biohazard Scatters on the second, third, and fourth reels. This awards 10 free spins, during which the game's primary mechanic—stacked wilds—becomes even more prominent. These wilds can cover entire reels, significantly increasing the potential for multiple winning combinations across the 100 lines. The feature can be retriggered if another set of three scatters appears during the round.

Risk Game Explained

Following any successful spin in the base game, you have the option to engage in the classic Endorphina Risk Game. You are presented with one face-up card belonging to the dealer and four face-down cards. Your goal is to choose a card that beats the dealer's value. A successful pick doubles your current win and allows you to try again, up to ten times, while an unsuccessful pick results in the loss of that round's winnings.
