Problem Battle

[PerpetualCreativity]

You get 5 minutes and you have increasingly hard problems that you try to solve (probably all multiple choice). 3 strikes and you're out, you compete with someone to see who can solve more in that time.

Maybe also a countdown style one where two people get the same question and have to race to answer.
