Connect as many same-colored blobs as you can without connecting the blue and green ones. The bonus blobs HOT and GOLD will help you to reach a higher score.
HOT Blob: There are two of them at the start of the game and one more is added for each 10 points.
GOLD Blob: Gained for each 100 points. It is also possible to buy them as an in-app purchase. The number of gold blobs is not wiped after the game is finished.
