This simple children's game probably falls into the 'Gnip Gnop' branch of the gaming tree. The object is to make your baby 'Roos hop to the top first. The game has a circular base into which 3 hoops (half hoops actually that are wicket shaped with flat tops) are inserted, each containing a 'Roo for each player (orange and purple). On both player sides, at the base of each hoop, is a paddle. On your turn, you strike a paddle and launch a 'Roo up the hoop where it hopefully stays on the top. You also try to knock your opponents 'Roos back down the hoops. Turns alternate between players. The first player to get all 3 of his 'Roos on top of the hoops wins the round. Two out of three rounds wins the game. - BoardGameGeek
