Benny the Beer — slot review and demo

Foamy Stackways™ mechanics in Benny the Beer

The slot is built on the Stackways™ system, where winning combinations are formed using ways-wins on a 5×4 grid. Two types of Stackways symbols can land on the reels: the regular one fills up to 4 positions vertically, while the Revealing one stretches the entire reel to 10 symbols in height. The stack only triggers if a winning combination is possible after filling, and the symbol to be stacked is chosen based on the longest line among existing wins.

Book of Stackways and Super Book: two free spins modes

Book of Stackways mode starts with 10 free spins and two random special symbols. If either of them lands on three or more reels, it fills the reels with stacks up to 10 positions high — the height depends on the numbers below the reels. When both special symbols trigger in the same spin, they stack in sequence, starting with the less valuable one. Two scatters add 2 spins, three add 4 spins. If 4 scatters land during the bonus, the round upgrades to Super Book of Stackways with four special symbols and additional spins. In Super Book, stacking follows the same logic, but symbols fill the reels in sequence from lowest to highest value.

96.17% RTP, medium volatility and bonus buy

The slot's RTP is 96.17% in the base version, with possible variants of 94.17%, 92.28% and 88.26% at different operators. Volatility is medium (3 out of 5), bets range from 0.1 to 100. The maximum win of x10000 is available in the base game and both free spins modes. Bonus buy is available: 120x launches Book of Stackways with 10 spins immediately, 300x launches Super Book. The BonusHunt FeatureSpins™ option at 3x the bet increases the chance of triggering the bonus fivefold, and paid forced spins guarantee from two Stackways symbols (25x) to three or more (75x).
