The outside players can also try to hit people, but they must be behind the back edge of the rectangle. An indoor variation on the dodgeball theme. You form a circle and choose a person to start. If you catch it, you toss it to someone else. If you drop it, you sit down.
Last person standing is the winner.
It's a good rainy day game and nobody gets hurt, and hopefully nothing gets broken. You need a large open space and at least enough soft-mediem hard balls to have one team have enough balls to have one per player. You can have a lot more, or a lot less. You divide into equell teams. You throw the ball tring to hit one of the members of the other team.
