Some sample (mathematical) categories you can try out:
- Mathematicians whose surname starts with ___

- Clopen sets
- Functions that are continuous everywhere but differentiable nowhere
- For n players: nth roots of 1
- Fields medal winners
- Misnamed Theorems
- Transcendental numbers
- Math Comics
