Left Click on a number and drag it onto the grid. When you place a number next to a number it's divisible by, the numbers will merge and leave behind the quotient! This scores points and frees up an extra space on the grid.

If you get a number you don't want to use just yet, drag it into the "Keep" folder so you can use it later. If you want to get rid of a number in your line, drag the number over to the trash can. You can only do this once per level!

To undo your last move, click on the arrow. You can only undo a limited amount of times. To restart the game, click on the double arrows.

HINT: If you merge two of the same number, they'll both disappear!
