Rules and Gameplay

The Zombies slot game by Smartsoft Gaming introduces a thrilling and horror-infused experience with its unique gameplay mechanics. Unlike traditional slots, Zombies operates on a 6×7 grid layout, challenging players to match symbols in clusters, also known as cluster pays, to win. The minimum bet starts at $0.20, while the maximum can go up to $50, catering to a wide range of players from cautious to high rollers. The game’s atmosphere is deeply rooted in the horror genre, featuring eerie backgrounds and thematic elements that enhance the player’s immersion into a world overrun by zombies.

Bonus Features

Zombies is packed with a variety of engaging and potentially lucrative bonus features designed to enhance your gaming experience and increase your chances of winning big. Here are some of the key bonus features:

  • Bonus Game: A feature that transports players to a new game screen to engage in an interactive, themed bonus round.
  • Free Spins: Triggered by landing specific combinations of symbols, granting players a number of free spins to increase winnings without placing additional bets.
  • Cluster Pays: Offers a unique way to win by matching symbols in clusters instead of traditional paylines.
  • Buy Feature: Allows players to directly purchase access to certain bonus features, offering more control over the gameplay experience.
  • Mega Symbol (3×3): A large symbol that can cover multiple grid spaces, significantly increasing the potential for big wins.
  • Scatter Symbols: These symbols can trigger bonus rounds or free spins when you land a specific number of them on the reels.


The Zombies slot game features a rich array of symbols that are integral to its gameplay and thematic expression. Symbols range from low-paying to high-paying and include:

  • Low-Paying Symbols: Card suits, which offer smaller payouts.
  • High-Paying Symbols: Thematic elements like Zombies, Dogs, and Werewolves that promise higher rewards.
  • Special Symbols: Wild symbols that can substitute for other symbols to form winning combinations, and Scatter symbols that can unlock bonus features.


Instead of traditional paylines, Zombies utilizes a cluster pays mechanic. This innovative approach requires players to form clusters of matching symbols anywhere on the 6×7 grid for a win. This system offers a fresh and exciting variation from standard slot games, where paylines are typically fixed or adjustable. The cluster pays mechanic encourages a more dynamic gameplay experience, as players aim to gather large clusters of matching symbols to maximize their winnings.

Minimum and Maximum Bet

The Zombies slot game by Smartsoft Gaming offers players a flexible betting range designed to accommodate both low-budget players and high rollers. The minimum bet that can be placed is $0.20, allowing for casual gameplay without a significant investment. On the higher end, players can bet up to $50 per spin, providing an option for those looking to invest more in pursuit of larger wins. This range ensures that the game is accessible to a broad audience, catering to varying preferences and bankroll sizes.

Game Jackpot

The Zombies slot game does not feature a progressive jackpot, but it offers a maximum payout of 500 times the player’s total bet. The game’s Return to Player (RTP) is set at 95%, which is considered to be below average for online slots. However, it operates on a moderate to high volatility basis. This means that while wins may not occur as frequently, the potential for larger payouts is heightened when they do happen. This balance of RTP and volatility makes Zombies a game of chance, where strategic bets can lead to significant rewards.
