Canny the Can and Mona the Mouse Help You Stack 'Em!

Stack 'Em by Hacksaw Gaming is a 5x6 cluster pays slot set in a whimsical cartoon world featuring Canny the Can and Mona the Mouse. Wins form by connecting 5 or more symbols vertically or horizontally. High volatility with an RTP of 96.20%. The cascade mechanic and stacking cluster mechanic set this apart from standard cluster pay games.

Gameplay Mechanics

When a cluster of 5+ symbols forms, all unconnected symbols (excluding Free Spins trigger symbols) are cleared from the board. The clustered rows remain as stacks, forming a base for new symbols to fall in. New clusters can then form with the stacked symbols, building multipliers on the existing cluster and adding any new clusters formed.

Free Spins Bonus

Triggered by landing 3+ scatter symbols. Start with 5 spins. The accumulating multiplier applies when connected to a cluster. The ? symbol randomly awards one of: extra lives/spins (hearts), an addition to the multiplier, or a multiplication of the multiplier.

Bonus Buy: 129x your base bet — among the more expensive in this game type. Sugar Rush (a similar cluster game) costs 100x at a higher RTP of 96.5%.

Verdict

Stack 'Em is a standout for its visual identity — darkly cute cartoon aesthetic unlike anything else in the Hacksaw or Pragmatic catalogue. The stacking cluster mechanic is genuinely unique. However, 96.2% RTP and a 129x bonus buy make it a harder sell than Sugar Rush, Sugar Rush 1000, or Le Bandit if winning is the priority. Play it for the experience; play something else if efficiency matters.

FAQ

How does the stacking mechanic work?
When a cluster of 5+ connects, all non-cluster, non-scatter symbols clear. The clustered rows remain as stacks on the board, forming the base for new symbols that fall in — enabling new clusters to build on top with multipliers.
What does the ? symbol do?
It randomly awards one of three things: extra lives/spins (hearts), an addition to the multiplier, or a multiplication of the current multiplier.
Is the bonus buy worth it?
At 129x, it is expensive relative to comparable cluster games. Sugar Rush offers the same game type at 100x with a higher RTP of 96.5%.
What is the max win?
10,000x your stake.
