About Mini Sudoku
Play Mini Sudoku online for free — the same logic as classic Sudoku on a smaller, faster 6×6 grid. Fill every row, column, and 2×3 box with the digits 1 through 6, no repeats. Great for a quick puzzle break or an easier entry point into Sudoku.
The Rules
Fill the 6×6 grid so every row, column, and 2×3 box contains the digits 1–6 exactly once — the same logic as Sudoku, in a faster session.
Step by Step
- Each row must contain the digits 1–6 with no repeats.
- Each column must contain the digits 1–6 with no repeats.
- Each of the six 2×3 boxes must contain the digits 1–6 with no repeats.
- Tap a cell, then tap a number to fill it in.
- The puzzle is solved when every cell is filled correctly.
Tips & Strategy
- With only six digits, scan rows and columns for the two or three missing numbers first.
- Boxes are 2×3, so a filled row often narrows a box down to one option fast.
- Mini Sudoku is a great warm-up before moving to the full 9×9 grid.
- Since there are only six digits total, keep a running mental tally of which ones are still missing from each row as you fill cells in.
