"Slap-stick fun for slap-happy players." From the box: It's a SLAP HAPPY Game chock full of lightning-fast reflex action. There are kooky SLAPPERS and 2 sets of whacky character cards; one ROUND, the other RECTANGULAR. The ROUNDS are spread out face up and the RECTANGLES are stacked face down. As soon as one rectangular card is turned up, the wild action starts. SLAPPERS fly... everyone trying to "slap" a matching ROUND CARD. The SLAPPER that picks up the right ROUND CARD gets to keep it. The player with the sharpest eye AND the quickest hand will get the most ROUND CARDS and be the slap-happiest winner!
