Abstract: A basketball game area for recreation consisting of multiple zones, each having at least one hoop and backboard combination, multiple shooting indicators, and obstacles which can be free standing, and/or affixed to the hoop or backboard. The location of the obstacle in relation to the indicator changes the trajectory required to shoot the ball into the hoop. The placement of each indicator increases the difficulty in placing the ball through the hoop. The game rules provide the order of proceeding through the courts and proceeding through the sequential shooting indicators within each of the courts. The first player proceeds to the first courts, attempting to shoot the ball through the hoop, avoiding the obstacle, scoring points for placing the ball through the hoop. The players continue shooting one at a time until all players have taken a shot at the first basket from each of the indicators and then continue to proceed through the courts.
