Working the Puzzle

To change a cell, you must first select it, which will highlight it. Then tapping one of the digit buttons will change the cell. In the default mode (solution mode) this will enter your answer in the cell.

If you've made a mistake erase it with the eraser.

Or use the undo/redo buttons to access the complete move history.

If you're not sure if you made a mistake, check the whole puzzle for errors.

And if you're hopelessly confused, start over using the Reset button with the Game option.
