Dice-A-Roo is a game of chance. It costs 5 NP per play, and you can cash out your current winnings at any time (if you don't roll a losing die). However, losing the game does not affect the items you obtained.

Some dice rolls remove points from the pot; these do not reduce your current total below zero.

Two critical rolls give you a chance of losing the game, or proceeding to the next die. These are not guaranteed.
