Symbols include low-paying card royals (Jack, Queen, King, Ace) and three high-paying monsters in purple, green, and red hues. Clusters of five matching symbols yield payouts ranging from 0.2x to 2x the bet, with larger clusters offering significantly higher rewards. Notably, the game lacks traditional wild symbols but compensates with the introduction of oversized “FAT” symbols that can appear randomly during spins.

• FAT Symbols: During any spin, oversized FAT symbols ranging from 3×3 to 7×7 may land on the grid, enhancing the potential for substantial wins by covering multiple positions and forming larger clusters.

• Free Spins: Landing 4 to 7 scatter symbols triggers the Free Spins feature, awarding between 5 to 8 free spins. Before the feature begins, a random pay symbol is selected to become the FAT symbol for the duration of the free spins. This FAT symbol starts as a 1×1 size and moves to a new position with each spin.

• Symbol Collection and Expansion: During free spins, instances of the chosen FAT symbol are collected in a meter. Accumulating specific numbers of these symbols progressively increases the FAT symbol's size:

  • Collect 30 symbols: FAT symbol grows to 2×2​

  • Collect 27 additional symbols: Grows to 3×3

  • Collect 24 additional symbols: Grows to 4×4​

  • Collect 20 additional symbols: Grows to 5×5​

  • Collect 16 additional symbols: Grows to 6×6​

  • Collect 12 additional symbols: Grows to 7×7​

Each expansion awards 1 to 3 extra free spins, increasing the potential for significant payouts.

• Gamble Feature: Before starting the free spins, players have the option to gamble:

  • Free Spins Gamble: Attempt to increase the number of starting free spins up to 8.​

  • FAT Symbol Gamble: Try to upgrade the selected FAT symbol to a higher-paying one.

• Ante Bet and Bonus Buy: Players can activate the Ante Bet feature by doubling their stake, which increases the likelihood of triggering free spins. Alternatively, the Bonus Buy option allows direct access to the free spins feature for 100x the bet, with a random number of scatters determining the starting conditions.
