The game is played using the keyboard. Use the cursor, keys left and right to move the blob you are controlling and spacebar to fire. Cursor up or down rotates the board allowing you to position the blobs all around the grid. Arrange the blobs in their colour groups. If you match the pattern and colour shown on the left of the screen, the group will be romoved. All other blobs of the same colour which are touching the pattern will also be removed scoring bonus points. If you remove all anchor blocks you will progress to the next level, the remaining ones will stay on the board.
