Stack ‘Em Slot Review

Take a moment and appreciate this Hacksaw Gaming's creation.

How to play

Gamble the Stack ‘Em video slot in a few simple steps, thanks to a clear gaming interface. The reel machine plays on a rather unusual matrix, with five reels and six rows. In place of the typical pay line structures, it incorporates the Cluster Pays mechanism. So, you’ll need to stack symbols on top of each other to boost your winning multipliers. Below the reels, you’ll notice an elaborate control panel. Use it to personalize your experience.

The default bet size in this video slot is €1. But, you can adjust the value between €0.20 and €100 using the Up and Down arrow keys. Press the Spin button after every reel spin to play manually. The Autoplay allows you to select up to 1,000 automated plays according to your choices. The Balance display shows what’s left of your bankroll. On the other hand, the Menu button opens advanced game options, including the info and turbo settings.

Symbols and payouts

The Stack ‘Em slot uses up to 10 unique symbols within its regular lineup. As mentioned above, the gameplay focuses on Cluster Pays, unlike the usual pay lines mechanism. Here, you need to match at least five connecting symbols of the same type. The matches can occur anywhere on the grid for you to receive winning combinations. Only the highest win per winning way pays out, with separate wins displaying during the win presentation.

Yes, various letters make the lowest paying symbols in this game. But, they aren’t the regular card royals, adding to the Stack 'Em's uniqueness. They include the letters A, G, E, R, T that pay between 0.1x and 25x the total bet. Then, a Leaf, a Dead Bird, a Skull, and a Snake are the medium-ranking icons. They reward wins anywhere from 0.25x to 100x your current stake. A thumbs-up is the highest rewarding icon, and it can deliver prizes of up to a lucrative 200x the bet! For the record, you can create up to 25+ matches per symbol.

Mona the Mouse is the scatter symbol that activates the free games. The Wild logo substitutes for all other icons, barring the scatter.

Best Stack ‘Em bonus feature

With the Cluster System, five or more symbols linking horizontally or vertically will create a win. After each payout, non-winning icons will disappear from the grid, with the winning ones dropping to the bottom. A value displays below each reel, showing the number of winning stacked symbols on that reel. All paying clusters multiply with the multiplier values they are above. For instance, if a clutch appears above 3x, 2x, and 4x, the values first add to a cumulative 9x. The cumulative value then multiplies with the winning cluster, and the process continues with more stacked wins.

Getting at least three scatters activates the Stack ‘Em free spins. You initially receive five bonus rounds, represented with Hearts overhead the reels. The mode continues until no Hearts remain. With each free game win, the multiplier increases by the number of winning icons. Furthermore, the mode contains an X symbol. When it connects with a winning group, the cluster multiplies with the factor above the grid. The ? symbol, in turn, gives extra spins or boosts your multiplier in the following possible outcomes:

  • 2-5 extra lives.
  • X2, x3, x4, or x5 imposed on the total multiplier.
  • Add either 1x, 2x, 5x, 10x, 25x, or 50x to the cumulative multiplier.

With the Bonus Buy, you can purchase the bonus feature directly from the base game.

RTP & Volatility

The theoretical Stack ‘Em RTP is a decent 96.20%. It depicts the average statistical payout over time. Unfortunately, there is no indicated volatility. So, bettors have to watch out for their bankroll as it’s hard to predict the potential win frequencies.
