Chain Addition

Test your mental math skills in this brand new and challenging game.

Start at 0 and add each number that flies across the screen. When they have all gone across, type the total sum correctly to advance to the next level. Each level, add one more number than the last.

You have three lives, but you can use a continue if you lose them all to keep going. More continues are available for purchase in the store. Compare your high scores with your friends and every player around the world through Game Center.
