Make paper valentine hearts amounting to half the number of players in the group. For example if your group has 20 players, you'll need to make 10 paper hearts. Make them big and decorate them in unique ways. Then cut each in half in a unique way using zigzag shapes or puzzle piece shapes. Each player is given half a valentine. Then all players must scramble to find the other half. If you can, try to match boys with girls. The first pair to find their match is the winner!
