I'll start with Curve Fever
In each game, there are a certain # of players. Each player moves little dot that starts making a trail behind it. If you bump into any of these trails, you lose for the round.
If a player loses, each surviving player gets points. The survivors will keep gaining points until there is only 1 person left. That would be the winner of the round. The first to reach a certain amount of points (depending on how many people have joined the game) is the winner of the game. This is a regular free-for-all game, with a team mode and clans as well.
I know there are a few players on CL, so feel free to make a subpost here with your username.
