Every player has two tokens on this board. One on the food track, one on the water track, and one (potentially) on or next to the exhaustion track.
If a player pays only a half ration of food or water on a given day, that player moves down one field on the track. If a player pays no ration on that day, he moves down two fields.
Once this is done, each player rolls a constitution check against the highest DC of either the water or food track.
If that player fails, his or her token is moved down a level on the exhaustion track.
If a player is on the starting point on both food and water tracks and takes a long rest, he goes down one level on the exhaustion track.
