Benny the Beer Demo & review

Every win in Benny the Beer can grow taller: a Stackways symbol turns its reel into a stack of 2 to 10 matching symbols, and the stacks multiply the ways up to 100,000. Hacksaw Gaming released it in October 2023 with two book-style bonuses and five options on its buy panel. Buyers get the most from it, since three of those options sell Stackways by the spin.

How Benny the Beer works

Five reels of four rows pay ways wins: a symbol pays when it lands on adjacent reels from the leftmost, and each copy on a reel adds ways. Three of a kind is the minimum. Benny tops the paytable, and the four card ranks share its bottom row:

On its own that is a modest ways game. Two things change it: Stackways, which can land on any spin, and the FS scatter, which opens the two bonuses. The Books are where the top end lives, and Stackways is the engine inside them.

How Stackways works

A Stackways symbol fills its reel with a stack of one paying symbol, from 2 to 10 high. Normal Stackways symbols give 2, 3 or 4, Revealing ones 5 to 10, and the number shows in the indicator under the reel. The game stacks whichever symbol gives the longest win, and it stacks only when that creates a win.

The indicators multiply. Each reel's number is how many of the winning symbol it holds, so the ways on a spin are the five numbers multiplied together, and stacks of 10 on every reel make 100,000.

Our fifth Triple Stack FeatureSpin shows the arithmetic. Kings stacked 5, 5, 4 and 5 high, with a single king on reel 4, which makes 500 ways. Each way paid the king's $0.70, so the spin returned $350.00.

How the bonuses trigger

Both bonuses give 10 free spins and turn chosen symbols into stacks that pay anywhere. They differ in how many symbols are chosen and what it takes to get in.

Book of Stackways

Three FS scatters start it, and the book picks two paying symbols as Special symbols for the round. When one of them lands on at least three reels at once, the indicators under those reels reveal a number from 2 to 10 and the reels are stacked with it. Those stacks pay as if the reels were next to each other, so a gap does not break the win.

Inside the round, two FS scatters add 2 spins and three add 4. Four upgrade the round to Super Book of Stackways with 4 more spins. The draw decides the round: Benny or the bomb as a Special symbol can pay well from a modest stack, while a card rank pays little even stacked high.

Super Book of Stackways

Four FS scatters start it, with four Special symbols instead of two, and every stacked symbol pays as if all five reels were counted in sequence. Two FS scatters add 2 spins and three add 4. Twice as many Special symbols means more spins where something stacks, but the draw still matters: four symbols can include three card ranks.

Bonus buy and FeatureSpins: prices and what you get

The panel sells both Books as single rounds and three FeatureSpins modes, charged per spin for as long as they stay on:

The two Stack modes do not open a bonus. They buy the base game's Stackways in bulk, which makes them the cleanest way to see the indicators multiply.

RTP, volatility and max win

The build we played gives the base game a 96.17% RTP, and every paid option sits slightly above it. Hacksaw's game page also lists lower versions, down to 88.26%, and the casino decides which one runs. The intro card rates the game 3 out of 5, which is the label here, while the buy panel calls four options High and Triple Stack Very high. Some listings call the whole game high volatility, but the intro card says otherwise.

Payouts stop at 10,000x the bet, in the base game and both Books alike. With Benny paying $4.00 a way for five, a few thousand Benny ways are enough to reach it.

Our Benny the Beer demo test

Stackways barely touched the base game. It landed on six of our base spins, never stacked more than three high, and its best showing was a two-high stack worth $11.00 on spin 62.

The natural Book of Stackways on spin 11 changed the picture. It drew the king and the camera, its two biggest free spins came from stacked cameras, and the round ended at $47.30. The bought Super Book showed the other side of the draw: jack, king, ace and camera, three card ranks out of four, and it returned $81.70 on its price.

Both Stack modes paid back more than they cost over their ten spins, led by a padlock spin worth $144.00 in Double Stack. BonusHunt brought no bonus in its ten.

A retrigger, the upgrade to Super Book and any stack above seven high never appeared, so those come from the rules. Ten spins of a mode and one round of each Book cannot rank the options against each other.

Is Benny the Beer worth playing?

Yes for the buy panel, no for the base game, and Double Stack is where we would start. By the rules, the Stack modes guarantee on every spin what the base game leaves to chance, and Double Stack is the cheaper of the two, with an RTP close to the top of the panel. The Books add the draw, which is the most fun in the game and the least predictable part of it.

Pick Book of Dead if you want the classic book round, one drawn symbol expanding across lines. Choose Benny the Beer if you want the drawn symbols to stack into ways, with several ways to buy the stacks directly.

In the demo, run ten Double Stack FeatureSpins first. Every spin lands at least two Stackways symbols, so you see within minutes how the indicators multiply.
