I played a similar game with some folks once, but I don't know the game's name. The person who knew the rule(s) explained that there was a planet that was like Earth, but it only had a subset of the things that Earth had. We guessed different things on Earth, and the teacher would tell us whether or not this other planet had them.

Some samples include: Planet has apples, green grass, trees, runners, and cheese pizza. Planet does not have bananas, plants, people, hamburgers, cats, dogs, houses.

I won't put the rule(s) here in case people want to try it.

I know it as "In a Cool World..."

As in, "In a cool world, there is jelly but no bread", and, "In a cool world, we go skiing, but never snowboard."

I learned this as the Green Glass Door. Everything in the title is also valid to go through the green glass door.

Planet has summer but not winter, and fall but but not spring, right?

[ndnichols]

Yup! I remember my eighteen-year old self being pleased with "Planet does not have Audi, but it does have Audi TTs!"

Looking at it again, I think the game works better spoken than written out like this.

[dpark]

Probably so. Written makes it a lot more obvious.

Not exactly the same premise, but I've heard it called "Queen Anne Likes".
