The one watching has a job too

Why this collection exists

In a house with three people and one keyboard there is always somebody sitting outside the game. This door picks titles where the third person is not abandoned: taking turns, keeping score, calling hints, or holding the same base together. Nothing here demands total silence from the person not playing, and nothing punishes a player because somebody said something over their shoulder. They can keep score, call out the keys, or simply remind the other two of the rule they agreed on.
