Stack’Em Slot Review

Stack’Em Slot Overview

Stack ‘Em is a Cluster Pays slot game from Hacksaw Gaming that offers wins of up to 10,000x your bet.

The aim of this hugely popular online slot game is to stack winning symbols on the reels, while the cascades will remove the non-winning symbols. Then there’s the bonus round that features a global multiplier that increases with each winning symbol.

The base game of this slot is exciting, but it is taken to another level when you trigger the truly unique bonus games.

The unique Hacksaw Gaming bonus round multiplier creates an unusual dynamic that can deliver payouts of up to 6,000x your wager. Landing a 100x multiplier or more isn’t all that difficult, so big wins may only be a spin or two away.

How To Play Stack’Em Slot

There are up to 10 unique symbols that appear in this Cluster Pays slot.

Your aim is to match at least five connected symbols of the same type.

These winning combinations can appear anywhere on the grid where matches occur.

The lowest-paying symbols in this game are the letter symbols, while the medium-paying symbols – Snakes, Dead Birds, Skulls and Leafs – pay out up to 100x your stake.

Keep an eye out for the Thumbs-Up symbols because they are the highest-paying symbol in this game. Landing a combination of these can pay out up to 200x your wager.

Mona the Mouse appears as the Scatter symbol, while the Wild Logo symbol is treated as a Wild symbol in this game.

Stack’Em Slot Features

As is often the case with online slots, this game revolves around a very exciting Free Spins Bonus.

Free Spins Bonus

Landing three or more Scatter symbols on the reels triggers the Free Spins Bonus and awards an initial five free spins.

Any winning cluster you complete during this bonus round will increase your win multiplier above the reels.

The increase is determined by the number of symbols in the cluster – for example – if there are 10 symbols in the cluster, you will receive a 10x multiplier.

Two new symbols are introduced during this bonus round – the X symbol and the Question Mark symbol. The X symbol multiplies the prize value of winning clusters if they connect with it. The Question Mark symbol will add 2-5 and multiplies any wins.

Bonus Buy

The Bonus Buy option gives you the chance to instantly trigger the bonus round – at the cost of 129x your bet.

Please note that this feature is not available to players based in the UK.

Stack’Em Slot RTP & Volatility
