FWIW I was aiming for this to be a "connections" level of difficulty. My sample size is small but the past week win rate is about 65%, which is actually very close to connections. But I also don't want to cause frustration, since a game is supposed to be fun. So I want to think through this hint idea, maybe it can help lessen the load and also give a fun dynamic of deciding when to use your hint, so I'm thinking you just get one and have to decide when to use it?
