I’d like to create a smart contact for a bet between me and my friend

Hi! Me and my two friends are trying to get into the habit of studying again. To motivate us we thought of creating a smart contract where money is sent to the others if two don't agree that one has studied.

I'm wondering if there are contracts like this, or with similar purposes that we could use?
