To play this Game just click on the numbered tiles on the game board until they add up to the given target number. Players participating in the same tournament will receive the same allocation of numbers. Add-It-Up is a fun and engaging strategy game based on the principle of simple addition. You are shown a series of target numbers and then must select a combination of numbered tiles that add up to the given target numbers.

You may deselect a numbered tile simply by re-clicking on it. Scoring is based upon your ability to clear a maximum number of tiles within the given time period. The more number tiles you use to get to the target, the more points you will receive.

By choosing combinations quickly (in under 10 seconds), you may also receive up to 10 Time Bonus points. After the first 10 seconds, you may still attempt to choose a matching combination, but you will not receive a time bonus.
