Stack 'Em is a 2021 release from Hacksaw Gaming, the studio behind Stick 'Em. It's a cluster-pays pokie set in a retro cartoon world with Canny the Can and Mona the Mouse. The most distinctive thing is how winning symbols stack on the grid, building reel multipliers that can push the top prize to 10,000x your stake. The default RTP is 96.2%.

The basics: layout, studio and how wins form

Stack 'Em uses a 5x6 grid, which is taller than the usual 5x3 layout. Wins come from clusters: five or more matching symbols connected horizontally or vertically. This is a cluster-pays mechanic, not fixed paylines, so the grid is the whole play area.

The theme is a cartoon world with Canny the Can and Mona the Mouse, continuing the story from Stick 'Em. Hacksaw Gaming released it in 2021. The grid gives more room for symbols to drop and stack, which is the core of the game's design.

What's structurally different is that winning symbols don't just disappear after a payout. Instead, they stay in place and stack, which feeds into the multiplier system described in the features section. This changes how you read the board compared to a standard pokie where wins clear and new symbols fall.

Setting up a spin: stakes and controls

To play Stack 'Em, set your bet using the selector, which ranges from $0.20 to $100 per spin. The game uses a 5x6 grid with cluster pays, meaning you need five or more matching symbols connected horizontally or vertically to form a win. There are no fixed paylines; the entire grid is the play area. The paytable and game info are accessible via the info button, usually located near the bet selector. Use the spin button to start a round. The bonus buy option is available at 129x your bet; switching it on purchases direct entry to the free spins feature, bypassing the base game. You would use it if you prefer to skip straight to the feature, but note the cost is fixed regardless of your bet size.

The features that do the heavy lifting

The key features, in the order they appear in the game's design:

  • Cascades: When you get a win, the non-winning symbols drop away, and new ones fall in. The winning symbols stay where they are, which is what allows stacking.
  • Stacked winning symbols build reel multipliers: Each time a symbol wins and stays, it adds to a multiplier for that reel. The multiplier can go up to 6x per reel, and with five reels that's a total of 30x across the board.
  • Free spins: Three or more scatters trigger free spins, starting at five spins. During free spins, there's a progressive global multiplier that grows as you keep winning.
  • 'X' symbol: This symbol applies the accumulated multiplier to your win. So if you've built up a multiplier through stacking, the X symbol cashes it in on that spin.
  • '?' symbol: This adds either extra spins or a multiplier boost, depending on what it reveals.
  • Bonus buy: You can buy direct access to the free spins feature for 129x your bet.

A simple example: suppose you get a cluster win on reel 2, the symbols stack, and the reel multiplier goes to 2x. If an X symbol appears later, that 2x applies to the win from that spin.

How Stack 'Em pays: RTP versions and top prize

The default RTP is 96.2%. Hacksaw's release notes list three RTP levels, with 96.20% as the default; the lower levels aren't published on the sources we checked. If you play a version with a lower RTP, say 94%, the difference is about $2.20 per $100 wagered compared to the default. That adds up over a long session.

The maximum win is 10,000x your stake. At a $1 bet, that's $10,000; at the $100 max bet, it's $1,000,000. The top prize requires the free spins feature and the multipliers working in your favour.

Before you play, check the RTP version in the game's info panel. It's the only way to know which version you're getting.

Playing it smart without a 'system'

Stack 'Em is high volatility. That means wins come less often, but when they do, they can be larger. For a $50 session, a sensible bet is around $0.50 to $1 per spin, giving you 50 to 100 spins to work with. For a $200 session, you can go up to $2 to $4 per spin, still keeping a buffer for dry spells.

The bonus buy costs 129x your bet. If you're betting $1, that's $129 per attempt. It's a fixed cost, so factor that into your bankroll if you plan to use it. No betting system changes the RTP; the house edge stays the same regardless of how you size your bets.

A practical rule: keep your bet small enough that you can survive 100 spins without busting. That's the arithmetic that matters.

Free play first: what the demo shows you

The demo version of Stack 'Em uses play credits but runs the same maths and RTP version as the real-money build at the casino you open it in. A demo session is useful for getting a feel for the game's high volatility: you can see how often cascades and reel multipliers build, and how the free spins feature triggers. You can also test how different bet sizes, from $0.20 to $100, affect your session length. With real AUD, bets are actual money, so bankroll limits matter. The demo lets you practice without financial risk, but remember that real play involves real losses.

Playing at Black Panther

Stack 'Em is available at Ricky Casino Just Casino, in AUD. There's a demo mode so you can try the game without spending real money. When you play for real, check the RTP version in the game's info panel, as it may differ from the default.

What works and what doesn't

What works

  • Cluster pays on a 5x6 grid offer a fresh layout.
  • Stacking symbols build reel multipliers up to 6x per reel.
  • Free spins with progressive global multiplier can boost wins.
  • Bonus buy at 129x bet gives direct feature access.

What to weigh

  • High volatility means long dry spells possible.
  • Bonus buy cost is steep at 129x bet.
  • RTP levels below default are not published.

Verdict

Stack 'Em suits players who like cluster mechanics and are comfortable with high volatility. The stacking multipliers and free spins offer real depth, and the bonus buy gives you direct access if you prefer to skip the base game. It's not for those who want frequent small wins; the volatility can drain a small bankroll quickly. The honest downside is that the RTP versions are unclear, so you need to check the info panel before playing.
