In game theory, a kingmaker scenario in a game of three or more players, is an situation where a player who is unable to win has the capacity to determine which player among others will. Said player is referred to as the "kingmaker" or "spoiler". No longer playing for themselves, they may make game decisions to favor a player who played more favorably (to them) earlier in the game. Except in games where interpersonal politics, by design, play a decisive role, this is undesirable.
