I read an interesting story recently, and to sum it up, a few college kids who invented a simple Frisbee game became millionaires!
Let me digress for a moment. A few summers ago a friend of mine received a game called KanJam as a gift. Now I love baseball and football, but Frisbee is not exactly my cup of tea. I changed my mind in about 3 seconds. This game is awesome!
You start out with 2 plastic garbage like bins about 50 feet apart. There are two teams, and each team member stands across from one another behind the cans.
Here's a quick description, courtesy of Wikipedia:
The object of the game is to score points by throwing and deflecting the flying disc and hitting or entering the goal. The game ends when a team scores exactly 21 points or "chogs" the disc for an instant win. A coin toss or similar procedure is used to determine which team goes first. The game is broken up into turns, with an equal number of turns for each team. However, this does not apply in the case of an instant win. The goals ("kans") are spaced approximately 50 feet apart. A team consists of two people each standing at opposing ends of the playing field. One player throws the disk, while the other acts as the "deflector," who is free to move anywhere, unlike the thrower, but the deflector may not catch, carry, or double hit the disc. The original deflector then throws the disc back to the original thrower from his end in order to score, and then the next team takes their turn. No points are awarded if the thrower goes over the line, or if the disc hits the ground before reaching the goal. Three points are awarded to the attacking team if the opposition interferes with the shot; if the attacking team has 19 or 20 points, they receive 2 or 1 points, respectively. Points are awarded for a Dinger, when the flying disc is deflected into the side of the kan (1 point), a Deuce (a.k.a. "direct hit" or "direct"), when the flying disc hits the side of the kan without help from the deflector (2 points), or a Bucket, when the flying disc is deflected into the middle of the kan through the top or the front slot (3 points). In addition, when a player throws the disc into the middle of the kan through the front slot or the top without help from the deflector, he scores a "chog" for an instant win. The game is over when a team scores exactly 21 points -- if a team scores more than 21 after a turn, the extra points are deducted from their score. In the event of a tie, tiebreakers are played to determine the winner, with the highest scoring team winning the game. Whatever team hits 21 first, doesn't matter if they went first or last, the opposing team slots that team is the victor.
I highly recommend giving this game a whirl. It's a blast!
