Knockout is a simple game to play. To start, everyone faces the basket in a single line, one behind the other. The first player in line shoots the ball. If they make it, they go to the back of the line. If they miss, they have to get their own rebound and put the ball in the basket before the person who was behind them makes their shot. If they can’t do that, then they are out of the game. The game keeps going until there is only one person left.
