Arrange the blobs on the board in their color groups. If you match the pattern and color shown on the left of the screen the group will be removed and set off a chain reaction. All other blobs of the same color which are touching the pattern will also be removed scoring bonus points. The grey anchor blocks can be removed if surrounded completely by blobs of a single color. If you remove all anchor blocks from the screen you will progress to the next level. However, any remaining blobs will stay on the board making the next screen harder! When you remove an anchor block, no chain reaction is started. Only the anchor and the blobs immediately surrounding it are removed. The game ends when the time runs out or no more blobs can be placed on the screen. Each level you get 10 seconds less to complete. The score for completing a pattern depends on its difficulty and the bonus is based on the length of the chain reaction. A further time bonus is awarded for any time remaining at the end of the level.
