Cubo: 3D Block Puzzle

Cubo is a 3D spatial puzzle game: spin neon polycubes in three dimensions to build a solid cube. Speed and Relaxed modes, a daily challenge, fully offline.

Cubo is a free iPhone puzzle game where you rotate glowing neon 3D polycubes and fit them together into a single perfect cube. It offers two ways to play, a timed Speed mode and a timer-free Relaxed mode, plus a fresh Daily puzzle every day and endless generated levels across Easy, Medium, and Hard. Cubo runs fully offline with no account, and ads are what keep it free.

Spin each piece in three dimensions, line up the gap, and snap it into place for 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, so 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 with no account, no internet and no waiting, so it works on a plane, on the train, or anywhere. Ads pay for the game: a banner on the home screen and a full-screen ad after every few solved puzzles, never in the middle of a solve. 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.
