My family has played this in the yard for years when we have company in the summer. I do not personally partake because I have an irrational (?) fear of frisbees, but my cousins are OBSESSED.
The set comes with two flying disks, instructions, and two goals that can be unfolded, so they're portable and easy to take to the beach, outdoor parties, or tailgates!
Promising review: "My nephews introduced me to this game and it is FUN! It's a team game, so it's fun to get the whole family involved. Basically, you have one member from each team by one of the goals while the other member stands on the other side of the field and throws the frisbee trying to score. The teammate close to the goal basket hits the frisbee to help it either go inside or touch the basket in order to get points for their team. Then that team member throws the frisbee back, attempting to do the same thing. The number of points each toss gets depends on if the frisbee goes into the basket without help, with help, or touches the basket with or without help. This is a great game for summer!" —A to Z for Moms Like Me
