A free game awarded to the player for exceeding a score threshold, completing a specific in-game objective, or winning a match at the end of the game. The replay is the coin-operated amusement industry’s fundamental reward mechanism: play well enough and you earn another game without inserting another coin.

Replay thresholds were operator-adjustable, allowing the route operator to control how frequently free games were awarded and balance player satisfaction against revenue per machine. A machine set to generous replay thresholds attracted more play but earned fewer coins per hour; a stingy setting earned more per game but risked driving players to competing machines on the route.

The legal status of replays shaped the industry for decades. In jurisdictions that classified a free game as a “thing of value,” replay machines were regulated or banned outright as gambling devices. This legal pressure drove the development of Add-a-Ball as an alternative reward mechanism and Novelty as a reward-free configuration. The distinction between a replay machine and a gambling machine was argued in courtrooms, city councils, and state legislatures across the United States from the 1930s through the 1970s, and the outcome in each jurisdiction determined which machines operators could legally place on location.

Replay remained the dominant reward mechanism for American Pinball from the Electromechanical era through the present day. Virtually all modern Solid State machines are configured for replay, though the mechanism is now implemented in software rather than the mechanical replay units and score motors of the EM era.
