Jail is a place on one of the four corners of the world you lie for doing bad things. These include: rolling doubles three times in a row, jaywalking on a cop, and picking up a card telling you to go to jail. You don't get to pass GO and collect your salary of $200. Bail is reasonably cheap, only being $50. You still get to collect your rent. You can bust out of jail if you like, by busting dice with rolled doubles and escape for free. You also may have a magical little card to get you out.
