About this game

Recommended for ages 6 and up. Younger children can play with a parent.

Are you ready to take your Sudoku skills into the next dimension?

Cube Sudoku transforms the world's most beloved logic game into an immersive 3D brain-training challenge. Instead of a single flat grid, you solve six interconnected 9×9 faces on a rotating 3D cube. Numbers wrap continuously around edges and corners, unlocking an entirely new realm of spatial deduction and satisfying "aha!" moments.

Whether you are a casual puzzle fan or a seasoned Sudoku grandmaster, Cube Sudoku delivers the ultimate mental workout!
