Funny blob formations will pop when they stick together. Have fun as you solve each jar filled gluey level.
Use the mouse to click the groups of blobs to make them explode in the jar. Use special items like bombs to get combos and points.
The larger you let the blobs get the more points you get. So your clicking should be designed to grow certain colors before popping them. Random will get you through the level but not a very good score.
