Knucklebones

Nero: The rules are simple. There are two bones under my paws, one is plain and the other was blackened by fire. You have to guess which paw I have the blackened bone under. We each get an even number of counting stones. If you guess right, then I give you one of my stones. If you guess wrong, I get one of yours. Whoever has all of the stones wins.
Doa: But to make the game more fun we like to make wagers. You can bet skill, questions, or favors. The loser then owes the winner whatever was wagered. A Skill wager for example, since Nero is a Hunt Master, you can have him hunt specifically for you for whatever the amount the bet was for. Questions wager means the winner can ask anything of you and you have to answer. And Favors... is exactly that. They can ask for a favor.
Scar: What sort of favor?
Doa: Whatever the winner chooses.
Nero: Within reason of course.
Scar: Of course...
Doa: Just don't play with Tomba... he cheats.
Nero: He doesn't cheat.
Doa: He always WINS! How is that not cheating?
Scar: ...I see... I'll keep that in mind.
Nero: So... shall we play?
