Developer Benny The Beer by Hacksaw Gaming is a 5-reel, 4-row slot with 100,000 ways to win and an RTP of 96.17% in the highest version shown. The game uses the Stackways mechanic, where matching symbols can expand across a reel to create larger winning combinations. Bet sizes range from 0.1 to 100, and the maximum win is 10,000x the stake.
The bonus structure centres on Book of Stackways Free Spins and Super Book of Stackways. In the Book round, two pay symbols are selected as Special symbols, while the Super Book feature selects four. These symbols can stack up to 10 rows high when they land across at least three reels, and retriggers are available. Four Free Spins symbols in one spin upgrade the round to Super Book of Stackways and add extra spins.
Players can use the demo version to play for free and practice before playing for real money. The slot also includes Bonus Buy and BonusHunt FeatureSpins options where available, allowing access to bonus features without waiting for a natural trigger.
