The game Threebound is perfect for when you want to be more active than just playing a game of H-O-R-S-E but it's too hot or you don't have the energy or you're too old to run an actual full court game.
The rules of threebound:
Shots from anywhere behind the 3-point line are worth 2, other shots are worth 1.
The order of players is designated before shooting begins. For this example we will call the players "A," "B," and, "C."
"A" may take a shot from anywhere behind the 3 point line, if "A" makes the shot the ball will be returned to "A" for another attempt from long range. "A" will score 2 points for every made shot from behind the line. When "A" misses, "B" must chase down the rebound as soon as "B" has touched the ball, "B" must shoot from wherever he/she ended up. If they make the shot, they are awarded 1 or 2 points (depending on if it was behind the 3-point line) and get the ball back to begin shooting from behind the line. When "B" misses, "C" gets the rebound, when "C" misses, "A" gets the rebound. The game continues until someone reaches 21 points.
