Seven Balloons app for iPhone and iPad
Start the game; balloons appear. Try to click them to let them disappear or the balloons will fall down to the bottom, then you fail. If your highest points are under 7, you can only play four groups of the balloons. When over 49 points, you can play 7 groups. Why 7? Just guess. Be quick because the speeds of the balloons are different. Good luck to you!
