Face off against an endless stream of bubbles. Keep them from reaching the top by adding, subtracting, dividing or multiplying the numbers inside. And you need to match the target number before the timer runs out. Fail to do either and you’ll lose health. Lose enough health and it’s game over.

Along the way you can earn powerups by dividing or multiplying. When you match a target you’ll earn coins that you can use to buy powerups to help you stay alive longer.

With every level the bubbles appear and move faster. Chose from Beginner, Easy, Medium and Difficult Settings. Each one makes it harder by increasing spawn rate, bubble speed and reducing perks – so you’ll always be challenged.
