Zum is a fun game to improve your math skills!
Clear the board as fast as possible by adding adjacent numbers to find the ZUM number, displayed at the top of the screen.
Move the selection square by dragging or clicking to highlight one or more numbers along the edge of the board. The selected numbers will be cleared when the last digit of the sum of the numbers is equal to the ZUM number. The more numbers are selected, the more points you get! An incorrect selection will cost you a point.
