About the Game
The goal of the game is to cross out all the numbers. You can cross out any identical numbers or numbers that add up to 10, standing next to each other horizontally or vertically. You can cross out the last number in a row with the first number in the next row if they are the same or add up to 10. Numbers that have been crossed out are no longer counted.
How to Play
Cross out pairs of numbers until you clear the entire playing field. Numbers form pairs when they are next to each other (horizontally or vertically) and equal to each other or add up to 10. For example: 2-2, 4-4, 4-6, 7-3, 9-1, etc.
To cross out a pair, select both numbers one by one with a mouse click or touch.
If there are no more pairs, but there are numbers left on the playing field that have not been crossed out, click the "Add" button to form new pairs.
