Participant that affects only the outcome of the game.
Usage
Judge’s role might be visible at the very end of the game or at the end of distinct stages of the game. Judge might affect the production of music only by the way of stopping it. Although usually they don’t produce sounds at all, in some arrangements Judge is a participant who makes one final (or almost final) cue or even a sounding note of the piece (i.e. gives a signal to end the game).
Judge might sometimes be considered a very specialized Conductor, but usually their actions are outside the flow of the performance. That makes it the least demanding role, and allows for the unique feature of this role, which is the possibility of forming the collective body of Judges. The most popular way how the group of Judges may decide on the outcome of the game (or of the phase of the game) is by voting.
