Capital B calling his casino "fraudulent" and "absolutely-not-crooked" is most likely a reference to some real life casinos suspected of being rigged.
An official promotional image of Capital B can be seen on the casino's pachinko machine, as well as an early concept art of what would become Tribalstack Tropics.
Kartos, Rextro, the Ghost Writers, and the Quills broke a rule where only the banker can give out Pagies. Rextro broke this rule twice, however, I.N.E.P.T. failed to take the necessary protocols.
Version 184.108.40.206 of Yooka-Laylee contains a glitch where the Casino Banker may fail to give all 19 Pagies even if they collected all 190 Casino Tokens. This may happen if the player exchanges too many at once. However, it is possible to exchange 10 Casino Chips at a time and still encounter this glitch. It is also possible to have extra Casino Chips even after 100%ing the world. This was fixed in the Purple and Green patch. The way how the glitch worked is that it auto-saved before awarding the Pagie.
There is a way to glitch out of bounds. Manage the camera to get inside the player in Helicopter form, and slowly hover through the boundary of any object and until the player warps to a different location or is killed by enemies, the world will glitch, making death by falling out of the world impossible. There will be no floor, allowing the player to fall out of the world.
Falling out of the world will not kill the player, instead making them fall infinitely until the player resets the game or warps back to Hivory Towers.
