sudoku cube

Sudoku like you've never seen it — on a 3D cube.

Sudoku Cube takes the classic number puzzle you love and wraps it around a rotating 3D cube with 6 faces. Every face is a full 9×9 Sudoku grid — but cells on shared edges appear on two faces at once. Place a digit and it fills in on every face that shares that cell. That's not flat Sudoku. That's cube logic.

🧩 A New Kind of Brain Challenge
If you think you've mastered Sudoku, think again. The cube's shared-edge mechanic forces you to think across faces simultaneously, turning every move into a multi-dimensional decision. It's the ultimate logic puzzle upgrade for Sudoku veterans and a fresh challenge for beginners.
