Drop9 - exhilarating puzzle app analytics for September 11

Recommended points ・All games are free to play! ・Simple rules just add the number of balls of the same color! ・There is no time limit, so you can play at your own pace! ・ There is also an save function, so it is perfect for playing in the gap time! ・Think about how to line up the balls, predict their movements, and exercise your brain! ・Experts can aim for higher scores and large-scale chains, and it's challenging! How to play ・If you hit balls of the same color, the balls will stick together and the written numbers will be added up. ・When the added number becomes "9", the ball disappears. ・When a ball is erased, if the adjacent balls are ``same color & number equal to or greater than the erased ball'', they can be erased in a chain. ・Let's aim for a high score by making full use of chains!
