Sudoku Six

A faster, friendlier take on sudoku — solve real puzzles on a 6×6 grid in minutes. No ads, no accounts, no tracking. Just you and the grid.

SudokuSix is sudoku, distilled.

Instead of the usual 9×9 grid, SudokuSix uses a 6×6 board split into 3×2 boxes — same logic, a fraction of the size. Puzzles that used to take twenty minutes now take five, without losing the feeling of actually solving something.

THREE DIFFICULTIES Easy, Medium, and Hard each generate a fresh, uniquely-solvable puzzle every time — no two games are the same, and every puzzle is guaranteed to have exactly one solution.

PLAY YOUR WAY • Normal mode for placing numbers directly • Candidate mode for pencil-marking possibilities, with an optional auto-candidate assist • Undo any move, erase a cell, or reset the whole puzzle • Conflicts highlight instantly, so mistakes never go unnoticed

TRACK YOUR BEST TIME Every difficulty keeps its own best-time record, with a little fanfare when you beat it. Reset a difficulty's record anytime you want a clean slate.

YOURS, AND ONLY YOURS No accounts. No ads. No analytics, no tracking, nothing sent anywhere. Your puzzles and your times live on your device and nowhere else. SudokuSix also works completely offline.

Quick to pick up, quick to finish, and quick to come back to.
