A "dead spin" refers to a spin in a slot machine or other casino game that results in no wins or payouts. During a dead spin, the reels spin but stop on symbols that do not create any winning combinations. This outcome can be frustrating for players, especially if it occurs frequently, as it means that the player is not progressing toward any rewards. Dead spins can be a standard part of game mechanics, and while they add an element of unpredictability, they can also lead to periods of inactivity or loss in gameplay, contributing to the broader experience in a game session.
