Simple and fun
Press on any gem on the board to change to the new color that you have selected from the allowed color. Try to create 4 or more of the same color to start a combo chain. Your score is the number of combo chains that is happening and not on the number of gems cleared. If you didn't fire any combo in 5 moves you lose the game so try to start one soon. Try to have fun and get the maximum score in the number of turns that you have.
