Mathematical questions will appear randomly on the screen with bubbles floating all around it. Each of the bubbles has a number, one of which is the correct answer to the question displayed above. Select the bubble which has the correct answer within the stipulated time to keep on playing the game. Exploding the wrong bubble would take away one chance. Giving 3 (three) wrong answers ends the game.
