>>949390Not sure why that guy is suggesting Kakegurui, it's nothing like Kaiji and is more coomerbait than anything else. Although Gamble Fish was a good middle ground of the two I found, you might enjoy that.
>cba to learn mahjongYou're doing yourself a big disservice since Mahjong is usually perfect for psychological shit. Akagi, Ten, Tetsuya etc. You can learn it by playing Mahjong Soul quite easily, just play a few games and once you understand it you can read them.
Anyhow some things that have mystery and/or psychological in them:
>Manga:Dorohedoro
Homunculus
20th Century Boys
Pluto
Akira (mostly action, but mystery of who akira is, motive's of characters, backgrounds of characters etc. Completely different to the movie if you've seen it.)
Gambling Emperor Zero (mostly psychological)
Voynich Hotel (there is a mystery around it, but it's secondary to pretty much everything else since it's more a comedy/horror thing)
Fire Punch (bit of a meme but you might enjoy it)
>Anime (not sure if they have manga so I'll just list them off here):Dennou Coil
Death Billiards (only an OVA but decent psychological and mystery)
Kaiba
Paranoia Agent
