A: Hey, I’m organizing a soccer match between the managers and the workers. Do you want to play?

B: Sure, count me in. I’m game.

Note: Saying “I’m game” means that you’re willing to try something. The word “game” means having a willingness to take a risk, to undertake something that could involve effort or injury to the participant. Some say it’s a word often used by breeders of pitbull dogs — a dog is “game” if he’s aggressive and undeterred by the displays of aggression that other fighting dogs might display.
