Benny the Beer Slot Review: Stackways and Book Bonuses

Benny the Beer puts a playful foaming-forest cast around a five-reel, four-row game with 100,000 ways. The key mechanic is Stackways: a symbol can expand into a stack across its reel, but the game only stacks when that change can produce a win. A second layer appears in the Book bonuses, where selected pay symbols spread across three or more reels

RTP and stake limits can vary by version and market. Check the information screen in the game you open. Maximum win is a ceiling, not an expected result.

Stacking with a condition

Two Stackways symbol types can cover a reel with identical symbols. Normal Stackways grows up to four rows high; the Revealing version can fill all ten symbol positions on a reel. The game chooses the symbol based on the longest winning length among wins already present, and it performs the stack only if a win is possible after expansion

Benny lists 100,000 ways and a 10,000× maximum available in the base game and both bonus modes. In practical terms, a large number of ways provides many left-to-right symbol combinations, but the stacking rule still asks whether the selected symbol can form a win. The potential ten-position expansion is therefore a visual maximum for the reel, not a promise that ten matching symbols will land or that the resulting symbol will pay at its highest rate.

Book of Stackways and its upgrade

Three free-spin scatters trigger Book of Stackways with ten spins and two randomly selected pay symbols marked special. When either special appears across at least three reels, it stacks according to the values shown beneath the reels, up to ten positions. If both qualify on a single spin, they stack in turn from the lower-paying symbol first

Four scatters in the base game trigger Super Book with ten free spins and four randomly chosen special pay symbols. It uses the same three-reel threshold and reel values, but stacks qualifying symbols one at a time from the lowest-paying upward. Four scatters during the regular Book also upgrade that feature and add four spins to the remaining count; additional two or three scatter combinations add two or four spins

RTP, volatility and trade-offs

The official data lists volatility at 3/5 and four RTP settings: 96.17%, 94.17%, 92.28% and 88.26%. The selected configuration depends on the casino, so the in-game information panel is the relevant reference for a particular session. The public game page provides no release date

The clear advantage is the shared visual language: both features enlarge a symbol across a reel, and both explain the threshold that allows it. The limitation is dependence on scattered conditions: a Stackways stack still needs a payable result, while Book symbols must land on enough reels and may need the right scatter count to upgrade. Four RTP settings also mean that an otherwise identical title can have different theoretical return values across operators

Strengths and weak points

Strengths

The stacking rule states its win condition, height limits and selection logic, while Book tiers specify scatter thresholds and the order for multiple expanding symbols.

Weaknesses

Reel expansion depends on a payable arrangement, Book specials need three-reel coverage, and the operator’s RTP setting can be materially lower than the top listing.

Our Editor’s View

Benny the Beer organizes its play around one appealing visual idea, then applies it in two different contexts. Stackways can enlarge a symbol when doing so creates a win; the Book rounds choose special pay symbols and expand them when they reach three or more reels. The order of multiple expansions is specified, and the four-scatter Super Book provides a clear upper tier
