Once loaded, click on a block that has another block of the same color touching it, that block and all of the blocks in that group will dissapear after a short while loading and the blocks above thnm will drop down.

Click the 'FINISHED' button when you are done, it will then reduce your score dpending on how many blocks are left and adjust your high score if needed.
