Mini Sudoku

How to Play

Fill every empty square with a number from 1 to 6.
Each row, each column and each 2×3 box must contain 1–6 exactly once.
Select a square by clicking it (or move with the arrow keys), then type a number or use the number pad.
Turn on Notes (or press N) to pencil in possible numbers. Erase or Backspace clears a square.
Conflicting numbers are highlighted in red. Complete the grid with no conflicts to win.

Look for rows, columns or boxes that are missing only one or two numbers.
Use notes for squares with two candidates — they often resolve each other.
Placing a number automatically removes it from the notes of its row, column and box.

Yes. The generator checks each puzzle and only removes a clue if the puzzle still has exactly one solution.

It uses a 6×6 grid with 2×3 boxes and the numbers 1–6, so a game takes a few minutes instead of half an hour.
