Defend yourself against an onslaught of mischievous Germz! The only hope is to match Germz to destroy them and reach your goals. Matching 4 or more will release powerful Antibodies that you can match to unleash a PowerBlast against the Germ hordes.
Use the mouse to match 3 or more like-colored germz to clear the board and reach the germ-kill goals for each level. Matching 4 or more germz together will release powerful Antibodies that can match with any 2 like colored germs.
