• Add up pairs of identical numbers (4-4, 2-2, 9-9) or those that make 10 in total (2-8, 3-7, etc.). Two numbers can be removed by clicking on them one by one.
• In a number game, pairs must be placed side by side, and you can cross them vertically, horizontally, and if one number is in the last cell in a row and the other is in the first cell in the next row of the grid.
• The goal is to cross out all the numbers and clear the playing field.
• If there are no more numbers left to cross out, additional rows are automatically added to the end.
