Cubes 2: clean geometry, expanding reels and a 10,500x top end
Cubes 2 is Hacksaw Gaming stripping a slot back to shapes and colour. There are no heroes or storylines here, just a minimalist grid of cubes, cluster wins and a set of mechanics that expand the board as you play. It is one of the studio's most abstract designs, and behind the simple look sits a 10,500x ceiling and the high variance the developer is known for. In our testing the clean style made the big moments feel especially stark.
The theme and cluster pays
The whole game is geometry. Cubes 2 uses cluster pays, so wins form from connected groups of matching symbols rather than fixed lines, which suits the tidy, modern art perfectly. The lack of a narrative is the point: the focus stays entirely on how the clusters build and break. It is a refreshing change from theme-heavy slots, and the minimalist presentation keeps your attention on the mechanics, where the interest actually lives.
The mechanics and expanding reels
The standout idea is the expanding reels. As you trigger the right features, the grid grows, opening more space for clusters and multipliers to do their work. Combined with the free spins, that expansion is how Cubes 2 reaches toward its 10,500x maximum. The base game is the setup phase, building toward the feature where the board is largest and the multipliers compound hardest. As ever with this developer, your only real levers are stake size and stopping point, and both deserve respect on a game this swingy.
RTP and volatility
Expect a default RTP in Hacksaw's usual mid-96% range, with the standard caveat that operators can run lower versions, so always confirm the figure before you play. Our RTP guide explains where to check. Volatility is high. The cluster format can produce frequent small wins, but the 10,500x ceiling depends on rare expansions and multiplier runs, so the swings remain significant. If you want to understand how that affects bankroll planning, our volatility guide lays it out clearly.
The bonus features
The free spins round is where the expanding reels, clusters and multipliers all come together for the headline potential. Like most of the catalogue, Cubes 2 is commonly offered with a feature buy at participating casinos. Buying the bonus does not change the long-run RTP and costs a large multiple of your stake, so it concentrates risk into a single purchase rather than reducing it. Our bonus guide covers why feature buys warrant caution on a high-variance slot like this one.
How to play Cubes 2
To play Cubes 2 sensibly, choose a stake small enough to survive the quiet stretches between expansions, and set a loss limit and time limit before you start spinning. Use the demo if your casino provides one so you can see the board grow without risking money. The minimalist design is calm and easy to keep playing, which is exactly why a pre-set budget matters: a tidy screen can still drain a balance one small spin at a time.
Is Cubes 2 worth playing?
Strengths: a clean and original look, a satisfying expanding-reels mechanic and a solid 10,500x ceiling. Weaknesses: the headline wins still hinge on rare events, and the variance can punish a careless bankroll. If you like abstract slots and accept the swing, Cubes 2 is a stylish pick. Play it for fun, never as income, and only at a licensed casino from our reviews. For more from the studio, read our Hacksaw Gaming review. 18+.
