I have a quality recommendation for you all. A smart show (albeit with extra exposition like all animu sadly) about Gambling and losing yourself to the thrill of cheating death, in a "meaning of life/Fight club sense". It's called Kaiji - Ultimate Survivor. I avoided the show for years because I typically judge books by their covers, but despite the utter shit quality of the character designs, the show turned out to be a hidden smash. It's by 2007 Madhouse so the suspenseful framing, pacing, and music are all DeathNote quality. The OP/ED are fantastic and lyrically fit the themes well...
