Kakegurui

The title states most of it. If you loved Yugioh as a kid, you'll love this. If not, it's probably not the show for you.

On the technical side of things, this show is absolutely gorgeous. The animation, the designs, the backgrounds are all incredible. The voice acting is phenomenal (both the sub and the dub, which is amazing). And the music is so good that I actually downloaded the soundtracks for both seasons.

The actual gambling is flashy, but it won't take you long to realize there aren't many stakes (much like Yugioh). But while the gambling aspects could be handled better (it is a gambling anime after all), most of the fun comes from watching these insane characters bounce off each other. They all have wildly different and entertaining personalities, and the writers and actors do an excellent job at selling their interactions.

As a gambling anime, it fails. But as a messed up school-comedy, it's amazing.
