Cudoku
Sudoku-inspired logic in three dimensions
In developmentAndroid, iOS and web
Cudoku is a number puzzle for people who enjoy Sudoku and spatial reasoning. Rotate a cube with six 3-by-3 faces and fill its 54 cells. Each face uses the digits 1 to 9 once, while connected groups across neighbouring faces add another layer of deduction.
Play from a small built-in puzzle collection with Easy, Medium and Hard options. Keep candidate notes, inspect the constraints on a cell and request a hint that explains its reasoning before applying a value. Undo, redo and saved progress let you explore a puzzle and return to it later.
Cudoku is in development for Android, iOS and web and is not yet offered for public download through this listing. Difficulty grades are provisional. The native app works without an application backend; the browser version currently runs as a local development preview.
