Bug fix
Game 9-0 is a addictive puzzle number game, very simple to play but difficult to solve (the last level 12).
The idea of the Game 9-0 is to swipe the selected cell towards empty cell , the cell splits to two pieces both decreasd by one. All numbers are shifted to the side direction of swiping what makes this game so difficult.
Continue until number is 0, which is deleted from the board. The game is finished when the board is total empty.
