Stack’em Slot Features

Stack’em has some standard features like Cascading reels,multipliers,free spins but these standard features work in unique ways in Stack’em and make it a high payout slot as you’ll find out below.

Cascading symbols with multipliers

You might have come across the cascading symbols feature in Gonzo’s Quest where it is called the Avalanche feature. On most slots with this feature, the winning symbols fall off the reels and new symbols drop down into your reels, kind of like in Tetris. 

But in Stack’em though you’ll notice that this feature works a bit differently. The winning symbols stay in their position and fall down whereas the other symbols disappear and are replaced with other symbols.

When this happens you’ll notice that underneath each reels there is a symbol with a padlock. The padlock unlocks when a winning symbol covers it. The unlocked padlock will reveal your multiplier.

If you can form more winning combinations thanks to the new cascade, the cascade will continue. If the new winning symbols fall in a locked reel the reel will unlock and reveal another multiplier.

The cascade continues until there are no more winning combinations and the multipliers in the bottom are added . This total multiplier is then applied to your total win in that spin.

This makes for some really big wins in the base game itself!

Free Spins Feature in Stack’em slot

When you get at least three free spin symbols on your reels you can trigger the free spin feature in Stack’em. You are initially awarded 5 free spins, displayed as hearts above the reels. The free spins mode continues until no more hearts remain.

Every time you hit a win in the free spins mode, the total multiplier will be increased by the number of winnings symbols.

There are some special symbols that are in play during the free spins in Stack’em.

  • The X symbol: All winning clusters that connect with this symbol will be multiplied with the factor shown above the reels
  • The ? symbol: This symbol will give you additional spins or increase your multiplier. The following outcomes are possible:

• 2-5 additional lives

• Add one of the following to the total multiplier: 1, 2, 5, 10, 25 or 50

• Multiply the total multiplier by 2, 3, 4 or 5

The cascading feature is not active during the free spins round.

Stack’em Slot Review Conclusion

Hacksaw is one of our favorite slot game studio and they have come out with another innovative slot. Although Stack’em looks like a slot with pretty standard features, the features become unique because of the way Hacksaw applies it.

Take for example how Hacksaw completely changes the way the cascading symbols feature works or the way the free spins feature works with the mystery symbols that were applied.

The theme of the slot is also pretty fresh, cool and triggers a feeling of nostalgia.

But the biggest pull factor of the slot is the potential for BIG slot wins. The multipliers keep flowing as if you are playing a Megaways slot especially in the free spins round.

If the free spins round featured more free spins and the cascading feature would still be active, we would’ve given Stack’em 5/5 but we will just deduct 0.5 points and give it an impressive 4.5 out 5 rating.

If you are looking for a high payout and fun slot go play Stack’em NOW!
