"Jail" is the third area you will travel to. Do not purchase anything from the blacksmith (bottom of the boat), the mage (middle of the boat) or the monster recruiter (top of the boat) during the first two areas. To travel to a new area, you have to complete all challenges for your current area. Then, select the monsters that you use to start a run, then select the arrow at the top of the menu. Note: Some of the challenges can be difficult without new gear.
