Spikeball

Ladder Golf
Players take turns throwing bolas (two balls connected by a string) at a ladder-shaped target, trying to wrap the bolas around the rungs to score points.
Gaga Ball
A variation of dodgeball played in a pit or arena, where players try to hit each other below the waist with a ball while avoiding being hit themselves.
Walk Together
Let's start by making a big circle between everyone. When I shout "STOP", everyone should start walking in a circle in a clockwise direction. When I shout "WALK", you stop walking, when I shout "TURN", clap your hands once, when I shout CLAP, turn around once, whether you are walking or standing. In this game, STOP means walk, WALK means stop, CLAP means turn and TURN means clap. We'll keep moving in a clockwise circle with the game, but if you don't follow one of the instructions, you're out! We will keep playing until there is a winner.
Trigger
Have a group sit in a circle. Every player is secretly given an action they must do on a "trigger". For example, the action might be to cough whenever a certain player in the circle talks. The goal is for someone in the middle to guess all of the triggers.
Kubb
Kubb, a traditional Swedish lawn game, involves players alternately throwing wooden batons to knock over wooden blocks (kubbs) before aiming to knock over the king. Elements of bowling and horseshoes are combined in this game, which is played on grass or sand.
Mr. Freeze
Pick one person to be Mr. Freeze. Have everyone playing the game move around the party as usual. When that person freezes, though, everyone else must freeze too. Whoever freezes last is out.
Medusa
Medusa is a game where everyone sit around a table. Everyone will put their heads down and count down from three, then have everyone sit up and look at someone else in the circle. If you make eye contact with someone else, you're out. If the person you're looking at is looking at someone else, you're safe. Repeat until everyone is out.
Crab in a circle
Large group forming a circle. One participant stands in the center in a quadripedal position. The participants who make up the circle shake hands and squat. The one in the center will try to get out, through those in the circle, who will move in all directions without letting go to avoid it. Anyone who "lets" it out or lets it escape should go to the center. There can be more than one person in the middle, to make it more fun.
