- Each of the nine vertical columns
- Each of the nine horizontal rows
- Each of the nine 3 x 3 boxes

To complete a puzzle, you can use these 2 methods:

First method

Click/Tap the desired number from the Number Pad on the bottom. The cells filled with this number (5 in our example) will be marked with a border. This number becomes the "active number". The mouse cursor will change to this number and clicking on any cell will enter it in that cell. Use this method if you prefer to solve a puzzle by focusing on one specific number at a time.

To delete an existing number click/tap and then click/tap on the cell with the number to delete.

Second method

Click/Tap on hand button . Now you can click on the desired cell and then use number keys of the keyboard to enter a number or use the Del key to delete an existing number.

Obs. On mobile or tablet device you can use only the first method.
