These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anvilicious: Don't rely on luck, never resort to magical thinking, and for the love of God, quit while you're ahead.
Big Lipped Alligator Moment: In Chapter 7 of Series 3, we are left on a cliffhanger with Kaiji staring at a box of Uno cards in a way that suggests it may be the next game. The President talks about it in a way that also suggests it, but Kaiji quickly declines, and by the third page of Chapter 8, it is a distant memory, never to be mentioned again.
Some of the Proverbs of Kaiji segments in season 2 come off as this, due to the way said proverbs can sound out of contenxt.
Crowning Moment of Funny - Mikoko's picnic with Kaiji in the third series; the scene was so popular that they based the second anime season's ED of it.
Pretty much every time Sakazaki talks about his daughter.
Otsuki's Villainous Breakdown; he waves his fists around and shouts NO COUNT over and over again. His lackey and friend Numakuwa gives him a tired look that just screams "wow, he really has lost it this time".
Muraoka suggesting UNO as the game for his gamble with Kaiji in series 3; the fact that it's the last page of a chapter combined with Kaiji's over-the-top reaction makes it look like some kind of bizarre Cliffhanger.
The Woobie - Some will argue that the whole point of this series is to see Kaiji lose tremendously, get back up in an inspiring and heart-winning manner...then lose even more tremendously. In the end, you just want to give him a hug or buy him some drinks after all that's happened to him (losing scads of money, betrayal and bullying, maiming, losing his comrades, being forced into slave labor, being harassed by a girl he doesn't like...the list goes on). Many fans will argue that Kaiji is indeed "moe", or moeGAR.
