How to play Mini Sudoku
6×6 grid · digits 1–6 · six rectangular 2×3 blocks
Free · no sign-up · same logic spirit as classic Sudoku
The objective
Fill the 6×6 grid so each row, each column, and each bold-outlined 2×3 block contains the digits 1 through 6 exactly once. There is only one valid solution for every ProPuz puzzle.
Block shape (important)
On this site, Mini Sudoku uses blocks that are two rows tall and three columns wide (a 2×3 rectangle), not square 2×2 boxes like some other apps. Always check the thick borders: they define where 1–6 must appear without repeats.
Controls on ProPuz
- Select a cell and tap 1–6 on the pad or keyboard.
- Notes — toggle pencil marks for candidates.
- Hint / Step / Complete — get help when stuck (challenge puzzles work the same).
- Undo — step back through moves.
