Deep Sea Adventure

You and your friends are divers looking for treasure at the bottom of the ocean. The twist is that you only brought one tank of oxygen! The more treasure you take, the more oxygen you use… but if you run out of oxygen, then you have to drop all of your treasure to surface.

Do you risk picking up one more piece of treasure, or do you head for the surface? Or maybe it’s too late, in which case you can try and deplete all the oxygen so that everyone drops their treasure.
