Rules and Gameplay

Big Bounty Bill takes players on a retro-futurist slots adventure through the Wild West, reimagined with a sci-fi twist. Set on a 5×4 grid, the game initially offers 1,024 ways to win, expanding dramatically as gameplay progresses. Players start their journey with a bet range from $0.30 to $300 per spin, catering to both casual players and high rollers. The objective is to land matching symbols on adjacent reels, starting from the leftmost reel, to form winning combinations. Expansion Symbols play a crucial role in unlocking additional rows and expanding the game grid, thereby increasing the number of win ways.

Bonus Features

Big Bounty Bill is packed with engaging bonus features designed to enhance the gaming experience and boost winning potential:

  • Expansion Symbols: Trigger the expansion of the game grid by shooting at blocker tiles, thereby increasing the number of win ways.
  • HyperSpins: Activated when landing 3 or more Expansion Symbols, awarding players with 3, 5, or 7 HyperSpins, and the possibility of further expanding the game grid.
  • Free Spins: Triggered by landing three bonus symbols, awarding players with 8 Free Spins. Expansion Symbols continue to play a crucial role, unlocking additional win ways.
  • HyperBonus: A feature buy option allowing players to directly enter the HyperSpins or Free Spins round by purchasing with a bet multiplier.


The symbols in Big Bounty Bill blend the Wild West with futuristic elements:

  • Low-value Symbols: Traditional card ranks from 9 to Ace.
  • High-value Symbols: A mix of thematic characters and elements including Big Bounty Bill, female and male outlaws, and cyborg versions of animals such as bulls and horses.
  • Special Symbols: Wild symbols substitute for all other symbols except the Expansion Symbol and the Bonus Symbol to form winning combinations. The Expansion Symbol is key to unlocking more of the game grid, while the Bonus Symbol triggers Free Spins.


Big Bounty Bill starts with 1,024 ways to win, which can increase up to 16,807 win ways through the game’s Expansion Symbols. Wins are awarded for adjacent symbol combinations, starting from the leftmost reel, with the number of possible winning combinations greatly expanding as players unlock more of the game grid.
