Cubes

I have had a few goes on Cubes from Hacksaw Gaming, and it is basically a digital nod to Rubik's Cube (the one Erno Rubik came up with back in 1974). You start on a 5x5 grid, win with 5+ connected colours, and it can grow out to 11x11. RTP is 96.35%, medium volatility, and bets run 0.20 to 100.

Symbols are as simple as it gets: just plain coloured cubes. You have six of them: green, yellow, red, blue, purple, and cyan/turquoise. No Wilds, no Scatters. They all pay the same, from 0.10x for a 5-cube cluster up to 40x once you hit 25+.

The little white X on the centre cube is the main gimmick. If your winning cluster runs through the middle, it slaps on a multiplier equal to the size of that cluster, and it can build up to 22x. Keep chaining wins and the grid expands in layers: 5x5 to 7x7, 9x9, then 11x11.

Free spins are triggered in a weirdly satisfying way: you need five different coloured winning clusters in one full round to complete the word CUBES above the grid. Then you pick from six mystery cubes for up to 10 spins and a random sticky colour, with the expanded grid not resetting. Nail a 70-cube cluster in the bonus and Colour Blast pays 2,500x. Max win is quoted around 3,000x (I have also seen 3,167x mentioned).

My take is it is a proper time-killer slot: minimal look, bright colours, and that tumbling cube motion with the soundtrack actually works. It does not feel like it is trying to be flashy, just moreish. I would not call it a high-roller thing, but for casual sessions, the expanding grid and 22x centre multiplier kept me spinning.
