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.
