Your job is to move the game pieces around the game board to make this happen. Clearing the board allows you to move the next level.
The challenge is that if you don't plan ahead, you might not be able get the pieces to the right location because they are blocked by other game pieces. Because sometimes there are an odd number of a certain types of game pieces, if you match them too soon, you risk leaving stray game pieces behind and then you won't be able to finish the level.
