To score points, drag over three or more matching pieces in a row. Once the pieces are matched, they will disappear and the pieces above the row will drop down.
Initally, you will have 60 seconds to score points. Once you scored enough points, you will advance to the next level, and additional time will be added to the current remaining time. To win the game, you will have to beat all 7 levels (score 1250 or more total points) within the allocated time.
A bonus game can be unlocked after you reach level 3.
Good luck!
