One idea could be a story where the Casino Cups are enchanted and King Dice has to solve the mystery behind it to save the casino. Maybe a rival has cast a spell on them to disrupt the normal flow of games.
You could create a character who is a master of reading the Casino Cups. This character could be an old fortune - teller type who has a mysterious past. They can add an element of mystery to the story as they seem to know things about King Dice and the casino that no one else does.

It's a bit like a master - servant dynamic, but with King Dice having some level of autonomy within the framework of serving the Devil.
King Dice is typically a prominent figure. He acts as a sort of enforcer for the Devil. He ensures that the rules in the Devil's domain, especially in the casino, are followed. He is often portrayed as very charming and sly, using these traits to manipulate others into doing the Devil's bidding.
