This is a match 3 game with a mathematical twist. Your goal is to complete each level by changing all gray tiles to yellow. Make matches over gray tiles to turn them to yellow. A match is made when 3 or more balloons of the same color line up vertically or horizontally on adjacent squares.
Each balloon has an addition or subtraction problem in it that is either true or false. Look at the problem and answer, decide if it is true or false and then click on the TRUE or FALSE button. Answering true or false correctly will cause the balloon to pop and the balloons above it to shift down one spot. Answering incorrectly will cause you to lose 1 chance. Chances are represented by the hearts at the top of the screen. Lose 5 chances and the level ends. Complete each level before the timer reaches zero.
