leavesLeaves is an environmental trivia game by sggc EOS, or Earth Operating System. When asked a trivia question about the environment, you can also choose to roll a die or use collected chips to bypass the problem. There’s also a cooperative element.

So, uh, “operating system”? “Leaves is a focal point, or operating system designed to transform multiple sources of information into inspiration through gameplay.”

Yeah, I have no idea what that means, either. I think it has something to do with the included cards (150 of them) being called a “starter deck”.
