How to play Stack'Em

Stack'Em, developed by Hacksaw Gaming, is a 5x6 grid slot that uses a cluster pays mechanic. Wins form when 5 or more matching symbols connect horizontally or vertically, and winning clusters trigger cascades.

Set your stake: Adjust your bet using the controls, with options ranging from 0.20 to 100 per spin.
Spin the reels: Press the spin button to start a round on the 5x6 grid.
Form clusters: Wins occur when 5 or more matching symbols connect in horizontal or vertical clusters.
Watch the cascades: Winning clusters disappear, and new symbols fall into the empty spaces. Cascades continue as long as new winning clusters form from the same spin.

Key Mechanics

FS symbols: Landing 3 FS scatter symbols anywhere on the reels triggers the Free Spins feature.
Multiplier symbols: During the Free Spins feature, a chosen symbol can add multiplier values to the bottom-row multipliers.
Extra spin symbols: During the Free Spins feature, a chosen symbol can add +1, +2, or +3 extra spins to the remaining free spins count.
X Multipliers: During the Free Spins feature, a chosen symbol can multiply all existing multipliers currently accumulated at the bottom of the grid.

Bonus Rounds

Free Spins Feature (3 FS symbols): Triggered by landing 3 FS symbols, this feature awards 5 initial free spins. During the round, a random symbol chosen on each spin can award extra spins, multiplier values, or X multipliers that amplify all current multipliers; these accumulated multipliers then apply to any cluster wins.

This bonus starts with 5 spins, and building multipliers and extra spins is critical; the outcome is highly sensitive to how these special symbols land in the early stages of the bonus feature, on US-facing social casinos.
