If Then Blitz sounds especially useful to me because I sometimes mix up necessary and sufficient conditions when I'm moving too quickly through a question. I like that these games let me practice one specific skill without having to sit through another full lesson. I'll give Monster Files a try too, since causal arguments are something I'd like to get better at spotting under time pressure.

I’m more into the games that make me slow down and pay attention to the exact wording. It’s satisfying when I catch a small logical twist that I would’ve missed if I rushed through it. Expecto Negation is a good pick, though. I like that it makes you actively test your understanding instead of relying on memorized patterns.
