Fill the grid area with pieces of glass, leaving no unfilled spaces. Glass pieces come into play from the conveyor belt, near the bottom of the play area. The larger the piece you place, the more points you get. Drop unwanted pieces into the bin. You lose 50 points for each piece you throw away. Some pieces have special items attached to them. Place these pieces to collect the items. You can use your special items by clicking the icons on the right side of the screen. Click on a piece of glass to pick it up and then click on a space to place it. Press space bar to rotate the current piece.
