The problem will fly onto the screen and the 0 in the answer selector will be highlighted. The arrow keys are used to highlight the correct answer and A is pressed to enter it. If the answer is wrong, the player gets one more chance to get it right.
200 points are earned if the problem is correct on the first try, 100 points if correct on the second try and 0 points if the problem is wrong on the second try. The game also keeps track of percent correct (first or second try) for each level. To proceed to the next level, the player needs to get at least 70% correct. The game is divided into levels.
Each level has 10 problems. The problems will be in the form of 9 + box = 9, box + 9 = 9, or 9 + 0 = box. The player must select the correct answer from the answer box on the bottom of the screen.
The first 4 levels use 10 as the maximum number. After 4 levels, the maximum goes to 12. After 4 more levels, maximum is 14. Levels continue in this manner until the maximum is 20. From the 20 point on, the maximum stays at 20 for all subsequent levels.
