Cubo: 3D Block Puzzle

Rotate, fit, and snap glowing polycubes into a perfect 3D block. New daily puzzle every day — race the clock in Speed or unwind in Relaxed. 100% offline.

Cubo is a glowing 3D block puzzle where you rotate and fit neon polycubes into a perfect cube. Spin each piece in three dimensions, line up the gap, and snap it into place — the satisfying click of a Soma-style solve, reimagined in electric cyan, magenta, and green on a deep-dark board. Simple to pick up, with a fit-the-shape hook that keeps pulling you back for one more solve.

Play your way. Speed mode puts you against the clock for a fast, focused block race; Relaxed mode drops the timer so you can solve at your own pace. A fresh Daily puzzle lands every day — keep your streak alive and watch it climb. With endless generated puzzles across Easy, Medium, and Hard, there is always another cube to crack, whether you have thirty seconds or thirty minutes.

Built to respect your time. Cubo runs fully offline — no account, no internet, no waiting — so it works on a plane, on the train, or anywhere. There are no forced ads interrupting your solve, and a single one-time Remove Ads purchase clears them for good. Just clean, glowing, three-dimensional logic. Train your spatial reasoning, chase a faster time, or simply zone out and build. Download Cubo and start fitting blocks today.
