Cubes

Cubes from Hacksaw Gaming adapts the iconic Rubik's Cube into a vibrant cluster-pays puzzle. The 5×5 grid expands up to 11×11 when clusters form, and winning combinations require five or more connected cubes of the same colour in rows, columns, or square blocks. Once a win locks, the grid expands, multiplying the number of available symbol positions and with it the odds of cascading wins.

The minimalist visual design—bright primary colours against a neutral background—mirrors the simplicity of the Rubik's Cube whilst modern animations and satisfying pop sounds reward each match. A centre "X" colour multiplier adds extra punch when the right cluster aligns across the multiplier position. The mechanic is straightforward but effective: land larger clusters, expand the grid, and chase the free spins round where sticky symbols and further multipliers amplify payouts.

With 96.35% RTP and low volatility, Cubes is relatively forgiving compared to modern cluster-pays games. Max wins of 3,000× are achievable but not the headline focus; instead, this slot rewards consistent, smaller-to-mid wins with frequent hit frequency (31.94%). The expanding grid mechanic also creates visual satisfaction—watching the grid grow with each win is intrinsically rewarding.
