First season of Promised Neverland is gold for that. Unfortunately Season 2 is unwatchable (I read they stopped following the manga) but season 1 is still 100% worth it

Weirdly enough, I had this thought when I was watching Dr. Stone. It’s more the over the top type because it’s so improbable that they’d come to the same conclusions.

I would honestly recommend sports anime like Haikyuu or Prince of Tennis for this kind of thing. Sports anime always lean really hard into the mental game and you’ll have whole scenes playing out in freeze frame or slow-mo while characters painstakingly walk through their plans. I’m a sucker for that kind of thing

I’d suggest “No Game No Life”, but it is a controversial title (especially about its fan service), so I also advise caution.

Code Geass has a similar vibe
