Enter the correct sum of all digits until you get a single digit.
2343 (2+3+4+3 = 12) and (1+2 = 3), the answer is 3

The number of digits start with 4. Each level has 15 seconds left for you. If you make it in 5 seconds, you get a bonus of 5 points and one star. Earning 5 consecutive stars will take you to next bonus level with extra digit.

Score: Score in each level depends on the time saved, level (number of digits), stars gained and bonus levels reached.

Note: You'll loose if you enter a wrong answer in first level with 4 digits. At higher levels you'll be taken back to one level down.
