How to play Mini Sudoku

• Fill every square with a number from 1 to 6.
• Each row and each column must contain all six numbers without repetition.
• Every outlined 2×3 box must also contain 1 to 6 exactly once.
• Keep the starting numbers unchanged.

Your first useful move

Look for a row, column or box with one missing number. For a harder square, cross off every number already used in its row, column and box before adding notes.

Playing on HubbardGames

Select a square, then a number. Use Notes to pencil in possibilities. A repeated number is highlighted; the puzzle completes when the grid is correct.

Can I practise without affecting the league?
