What is a zero-sum game?
Zero-sum is a situation in game theory in which one person’s gain is equivalent to another’s loss, so the net change in wealth or benefit is zero. Futures and Options trading in the share market is the closest match for zero-sum game. Chess, tennis kind of play falls under this as only one person can win that. Poker and gambling are also popular examples.
