Rat-Snake is a gambling game that requires two six-sided dice to play. Players will roll dice on a mat, wagering their ante in a silo for a payout. The game was created in the fictional universe of Lankhmar, played by characters in the game. It was made real and published by Goodman Games and sold through their website. The game comes in a tube and includes six dice (although only a pair of dice are used per thrower.) Players take turns as the "Thrower" rolling dice. They pay a six coin ante, and roll the dice. If the dice show rats they lose coins out of their silo. If the dice show snakes they gain coins in their silo. After each roll players can decide if they want to keep playing or stop. If players lose all their coins they are out of play. Additionally, players may make side bets on the active roller.
