It is commonlyplayed with four players and requires 2 stakes and four horseshoes The object ofthe game is for players to toss their horseshoe as close as possible to the stakeon the opposite end of the "court" The ultimate goal is to get a "ringer", or ahorseshoe that lands so that it completely encircles the stakeTo play the game, a member of each team stands at opposite ends of the courtThe team members on one side each pitch two horseshoes toward the oppositestake. The team members on the opposite side determine the scoring for the roundThree points are awarded to every ringer and two points to every "leaner" (or ahorseshoe that lands leaning against the stake) If there are no ringers or leaners,one point is awarded for the two closest shoes Once the scoring has been decided,those players pick up the horseshoes and pitch them back, with the players on theother end scoring this time The game is typically played to 21 points, so the firstteam to score 21 points is declared the winnerWhat is the purpose of the above passage?
