We took the classic game of 4 Square, added a bit of your favorite net spiking game and came up with our new 4-Circle game. Simply lay out the 4 Super Hoops in a 2’ x 2’ grid to create a square, lock them together with our exclusive hoop clips and you’re ready to play on any hard, flat surface indoors or out. For indoor play use the super lively foam Smash It ball and the 6” playground ball for when you take things outside. Downloadable activity guide includes options for games of 4-Circle, 3-Circle, 2-Circle and more. Includes 4 Spectrum™ Super Hoops, 4 Hoop Clips, 1 Smash It ball, and a 6” playground ball.
