Collect the most gems without getting your hands dirty in this card game of balancing and dexterity!

Microbes challenges 4 to 8 players, ages 9 to adult, to claim as many gems as they can by slapping the cards. If you’re the fastest you’ll get the gems – but watch out! You’ll also get the germs. You must balance collected germ tokens on the back of your hand, because if enough of those germs fall off, then all of your gems will be worthless! Can your hand hold any more germs? If not, better find a handwash card quick!
