This is the story (comedy?) of Kakegurui.
The show started out with promise. The characters had a bit of a... uniqueness about them. The main heroine is completely crazy, as you'll find out in like episode 2, but that isn't necessarily a bad thing in itself. It's fine to have an unhinged character to shake up the story a bit.
However, at some point a writer needs to realize when they've gone too far. There's a point where the story just becomes way too unrealistic and overly dramatic. The problem with Kakegurui, is a typical problem you actually see in Shonen anime or whatnot. As the stories go on, battles need to get bigger and more dramatic. You go from fun, realistic battles, to battles where suddenly two characters have the powers of gods who just go at it and do all sorts of weird stuff.
A similar situation comes up in this show. The bets become larger, and the insanity also becomes larger somehow. The writers feel a need to make the characters more and more insane as the series goes on, as if it's going to shock the viewer. And how do they convey a message of insanity? You have characters who touch they faces a lot. I'm pretty sure in every single episode someone's eyes have glowed up and their hands have molested their own faces.
As if that wasn't enough, you also have the protagonist (?) (he doesn't really do much the whole story) whose only purpose is to make comments on how crazy everything is. He's always freaking out about the heroine and how crazy her bets are, too, which is funny because the main heroine has superhuman luck so I don't see why he'd ever be concerned.
Oh, speaking of which, this show isn't really about strategy. Like, yeah, they act as if there's a strategy to it all, but really it comes down to the fact that a character was lucky enough to actually carry out that strategy in the first place.
Everything is over-hyped in this show. At some point it kinda becomes funny. You got characters that masturbate over life or death situations, and characters that mutilate their own bodies for SEEMINGLY NO REASON (see episode 11). Also, people's hair changes color after bets now, apparently. I honestly have no idea what the writers are thinking. It's possible that, while trying to make their characters increasingly more unhinged, they have also become insane themselves. Prayers go out to them tonight, my friends.
So yeah, this series is becoming worse and worse as it goes on. Don't let the promise of the first half of the series fool you. It's managed to accomplish in 13 episodes what it usually takes shounens hundreds of episodes to do - become completely ridiculous.
Additional elements:
Art: is good
Sound: is okay (OP and ED are very fun)
Character: worst part of the series. There is absolutely no character development or even personality besides 'insane' or 'freaked out' throughout the entire series.
Story: bland and linear - absolutely unsurprising.
enjoyment: ehhhh fair, it really just took the biggest dive in the final couple episodes
overall rating: 5/10 and that's MERCIFUL imo
