Rules and Gameplay

UFO Joe immerses players in an exhilarating sci-fi adventure with its 7×7 gaming grid, designed to engage fans of aliens and UFOs. This slot machine from Popiplay utilizes cascading mechanics and cluster pays, where winning combinations are formed by clusters of matching symbols rather than traditional paylines. Symbols disappear to allow new ones to fall, potentially creating more wins in a single spin. The game’s RTP stands at a generous 96.26%, offering players a fair chance of winning in the long term. With very high volatility, players should prepare for a thrilling ride with potentially substantial payouts but also periods without significant wins. The stakes range from $0.20 to $1000 per spin, accommodating both casual players and high rollers.

Bonus Features

UFO Joe is packed with an array of bonus features that significantly enhance the gameplay and winning potential:

  • Wild: Substitutes for all symbols to help form winning combinations.
  • Free Spins: Triggered by filling the UFO Meter, offering players additional chances to win without placing further bets.
  • Expanding Reels: Increases the size of the grid, offering more symbols and potential wins.
  • Progressive Bar: Fills up with each win, leading to the activation of random features.
  • Random Features: Including Mass Attack, Take Over, Merger, Starlight, BigBang, Eclipse, Interstellar, and Blaster, each offering unique gameplay enhancements and opportunities for increased payouts.


The reels of UFO Joe are adorned with symbols that perfectly capture the game’s extraterrestrial theme:

  • Spaceships: High-value symbols that offer bigger payouts.
  • Planets: Medium-value symbols, key to forming substantial winning clusters.
  • Alien Artifacts: Unique symbols with special gameplay functions.
  • Low-value Symbols: Represented by A, K, Q, J, and 10, these symbols are the most common and offer smaller payouts.


UFO Joe departs from traditional slot game designs by not utilizing standard paylines. Instead, it employs a cluster pays mechanism, where wins are generated through clusters of matching symbols. This innovative approach offers a refreshing and dynamic gaming experience, with numerous opportunities for creating winning combinations across the expansive 7×7 grid.
