You need a net and you will need a soft ball which is big.
Have everyone split into 2 groups.
One team starts, hits the ball over the net, the opposite team hits it back... and this goes back and forth until the ball falls. If the ball falls on the opposite side, your team gets a point (and vice-versa). If someone hits the ball outside of the pool, the other team gets a point.
The first team to get 11 points is the winning team.
