Cube Sudoku
3D Sudoku on a cube
Six faces. One cube. One connected puzzle — buy once, no ads, no subscription.
Version 1.0 is being prepared. The link will appear here once the app is released.
One puzzle that folds around every edge
Each of the six faces carries a complete 9×9 Sudoku. Along edges and corners, neighbouring faces share the same numbers: a digit you enter on the front appears on the side at the same moment. You are not solving six puzzles side by side, but a single connected one.

What is inside
Five difficulty levels
From Easy to Master — separated by the technique required, not by how many digits are given. Every puzzle has a unique logical solution; guessing is never needed.
Hints that explain
When you are stuck, Cube Sudoku shows the next forced move rather than the answer — with a short explanation and the relevant cells highlighted. You learn the technique instead of skipping it.
Daily Cube
Every day, the same puzzle for every player worldwide. Jump in and back to your current game without losing progress.
A cube you can handle
Turn it freely with your finger; on release it settles gently onto a face, an edge, or a corner. The digits always stay upright and readable.
Tools like on paper
Pencil notes, unlimited undo and redo, a timer, and optional conflict highlighting. Your game saves automatically, including the full move history.
Usable by everyone
VoiceOver covers the board and the shared cells. Reduce Motion turns off movement without losing feedback. iPhone and iPad, portrait and landscape.
