We use this chart to mark which chits have already been played by placing a penny on the chart after a particular chit is drawn from the bag. Chit depictions without pennies on them are what is left in the bag.

Yes, this information is "easily trackable" but it takes time and mental space to figure out exactly what those "last 5 chits in the bag" are at the end of each round... Anyone who is playing to win stares at the board long enough to figure out exactly what they are, so why not just display it?

By using this chart that time and energy can be used to relax and enjoy the meaningful and interesting game decisions instead.
