Cube Clear is a relaxing yet addictive block puzzle. Each turn you're given three shapes to place anywhere on an 8×8 grid. Fit them together to complete full rows and columns — every line you fill clears away and scores points, and clearing several at once triggers a big combo bonus. There's no timer and no falling blocks: the only pressure is space. The game ends when none of your three pieces can fit, so every placement is a small puzzle. Play free in your browser on desktop or mobile — no download, no sign-up.
Skills Cube Clear trains
Cube Clear is built so that spatial reasoning is the thing that gives out first, which is what turns a round into practice rather than just play.
Spatial reasoning
Spatial reasoning is the ability to picture shapes, paths and space in your head — to see where a piece will fit or where a path leads before you move anything.
More games for spatial reasoning →Decision power
Decision power is how quickly and how well you choose between options when you cannot have all of them — picking the move that is good enough, right now, instead of freezing on the perfect one.
More games for decision power →Problem solving
Problem solving is the ability to look at a situation you have not seen before, break it into smaller parts, and find an order of steps that reaches the goal.
