A poker tournament is an event in which poker players compete for all or part of a prize pool. Each player pays an entry fee and initial buy-in for a set number of tournament chips. The chips are non-negotiable, having no cash value except at the end of the tournament. The contestants play until all but one or a few are busted; the top finishers divide up the prize pool according to the tournament rules. The game's stakes increase with time to hasten the tournament's end.
