How to Play Large Sudoku

Basic Rules

Fill the board so every row, every column, and every outlined box contains each number once.

1. Tap an empty square on the board.
2. Tap a number from the large number pad.
3. Use Erase if you want to clear your own entry.
4. Use Check Errors when you want a calm hint.
5. Use Show Answer only when you are ready to see the solution.

Given numbers are part of the puzzle. They stay fixed and cannot be changed.
