Stack ‘Em: Slot Overview

Hacksaw Gaming revisits one of its early mascots, Canny the Can, in a new release called Stack ‘Em. It follows on from Stick’ Em, the title that marked Hacksaw’s move from scratch cards into full-scale slot development. The original’s straightforward presentation, lovable cast, and quietly devilish mechanics became a winning mix the studio has echoed across a run of highly playable games ever since. In that sense, Stack ‘Em works as a handy gauge of how far Hacksaw has come. There’s no reinvention attempt here—Stack ‘Em delivers the same stripped-back but cleverly layered design expected from a Hacksaw launch.

Visually, the most noticeable change is the set of icons filling the 5×6 game grid. The plain tiles from the first game have been swapped for symbols with a more esoteric vibe. Canny remains on the right, bouncing along as usual, while Mona the Mouse appears on the left, moving in a way that recalls early Mickey Mouse cartoons—an appealing nod to Stick ‘Em’s 1930s-inspired style. The piano-driven swing soundtrack also returns, keeping things lively and picking up pace during the bonus round. If it becomes distracting, you can silence the music and focus on the crisp pop of falling symbols and the sound of wins landing.

Although it isn’t officially part of the Pocketz Series, Stack ‘Em runs smoothly on any device and supports stakes from 20 p/c to $/€100 per spin. With Highly volatile behavior, it can swing wildly—switching from friendly to brutal without warning. In one session, there were only two hits across the first 50 spins; in another, two free spin rounds arrived in about the same timeframe. Treating Stack ‘Em as a game where anything can happen is a sensible mindset, especially since it offers bigger potential rewards than Stick ‘Em did. The RTP is set at 96.2%, regardless of whether you buy the free spins or trigger them naturally.

The paytable features a quirky mix of symbols. From low to high, there are A, G, E, R, T, a leaf, a dead or sleeping bird, a skull, a snake, and a thumbs up. If there’s a deeper message behind the selection that we’ve overlooked, feel free to enlighten us. In terms of payouts, a cluster of 25+ matching symbols returns 25 to 200 times the stake. There’s also a wild tile, which can appear across the grid and substitutes for every symbol except the free spins icon.

Stack ‘Em: Slot Features

Stack ‘Em runs on a cluster pays mechanic where a win is formed by 5 or more matching symbols connected vertically or horizontally. When a win lands in the base game, all non-winning symbols disappear, and the winning clusters settle at the bottom of the grid. Fresh symbols then drop in, and if new winning groups form, the cycle continues. Alongside this, the count of winning symbols on each reel generates a matching multiplier shown at the bottom—up to 6x per reel. Payouts are boosted by the combined multiplier total (up to x30), and these multipliers reset between paid spins.

In addition to the stacking cluster mechanic in the base game, there’s a free spins feature running in parallel. You can enter it naturally by landing at least 3 scatter symbols. The round begins with 5 free spins, shown as hearts above the reels. Each time a cluster wins during free spins, the win multiplier above the reels increases by the number of symbols in that winning cluster—so a 10-symbol cluster adds +10, for instance. Two extra symbols are also introduced during free spins:

• ‘X’ symbol – When winning clusters connect with the ‘X’, the payout for that win is multiplied by the current multiplier value.
• Question mark icon – It can add 2-5 lives, add 1-50 to the multiplier, or multiply the multiplier by 2, 3, 4, or 5.

If you’d rather not wait for the free spins symbols to appear naturally, the bonus buy feature is available. Paying 129x the bet grants immediate entry into the bonus round.

Stack ‘Em: Slot Verdict

Stack ‘Em offers a neat snapshot of how much Hacksaw has evolved since Stick ‘Em arrived. At the time, it wasn’t clear what the scratch card specialists would deliver in the slot space. They didn’t take long to establish themselves, releasing games that felt distinctive while remaining easy to pick up and play. Over time, their titles have also leaned harder into high volatility and big-win hunting, despite their compact style. Stack ‘Em fits that pattern perfectly—exactly the kind of Hacksaw experience players expect: adorable on the surface, unexpectedly dangerous underneath.

It’s also another strong example of Hacksaw Gaming’s talent for building features that look simple but can be both ruthless and rewarding. The free spins round can be a genuine ride. One moment you’ve built an enormous multiplier… with nothing lining up to actually use it. Then, suddenly, an ‘X’ drops into the perfect spot and turns an average hit into a standout payout.

Starting with five free spins is fairly modest, and although extra hearts can extend the round, it often plays out as a brief, intense burst. It can be mildly annoying to land extra hearts when they’re unnecessary, and it happens more often than you’d expect. Still, it’s preferable to having too few, and most players will take any edge they can get while chasing wins of up to 10,000 times the stake – roughly five times what Stick ‘Em offered.

All things considered, Stack ‘Em is pure Hacksaw Gaming—well suited to players who enjoy pursuing big payouts and can handle a cute but unpredictable slot that can turn on you just as quickly as it rewards you.
