How to play Mini Sudoku
- Fill the 6×6 grid so every row contains the digits 1 to 6 exactly once.
- Every column must also contain 1 to 6 exactly once.
- The grid is split into six 2×3 boxes (two rows, three columns). Each box must contain 1 to 6 exactly once.
- Given digits are fixed. Tap an empty cell, then tap a number. Use Notes to pencil in candidates.

A worked example
This easy example starts with 18 digits, so 18 cells are empty. The thick lines mark the six 2×3 boxes.
Look at row 1, column 1. Its row already has 1, 3, 4, 5 and 6. That leaves only 2, so 2 goes there.
Every digit you place rules itself out for the rest of its row, column and box, which narrows down the cells around it. The finished grid is on the right.
Difficulty levels
| Level | Board |
|---|---|
| Easy | 6×6 grid with 18 digits given, 18 to fill |
| Medium | 6×6 grid with 14 digits given, 22 to fill |
| Hard | 6×6 grid with 11 digits given (sometimes a few more), about 25 to fill |

Mini Sudoku tips
- Start with the digit that has the fewest places left, usually one that already appears most often.
- A 2×3 box shares two rows and three columns with its neighbours. A digit in a box's top row goes in the bottom row of the box beside it.
- Look for a cell where only one digit fits (naked single) before guessing anything.
- With only six digits, "where can the 4 go in this row?" is often faster than "what goes in this cell?".
