Gambling is definitely not your get-out-of-jail-for-free card. This isn’t Monopoly. Besides, gambling is highly discouraged, especially when you’re trying to prove that you’re a reformed man. If you want to get out earlier than scheduled on good behavior, then hide these. But then again, it can get pretty boring when all you have to do is stare at the same faces day in and day out. Sneak in and play hooky to pass the time away. If you want a foolproof set of dice, make them edible. Just put them in your mouth and chew the moment the stiff in uniform walks past you.
