Mini Sudoku

How to play Mini Sudoku

• Fill every empty square with a number so that each row, each column and each box has every number exactly once.
• Tap a square, then tap a number. You can also use your keyboard.
• Press Check to see if any numbers are wrong (they turn red) and Hint to fill in one number for you.
• Start with the 4 by 4 grid, then try the 6 by 6 grid. Every puzzle has exactly one solution.
