Eton Fives

Eton Fives, a derivative of the British game of Fives, is a handball game, similar to Rugby Fives, played as doubles in a three-sided court. The object is to force the other team to fail to hit the ball 'up' off the front wall, using any variety of wall or ledge combinations as long as the ball is played 'up' before it bounces twice.
