"Re-spins" are an additional feature in some online slots in which you are given the opportunity to re-spin one or more reels after a spin without any further wagering being necessary. This can help the player create better winning combinations by locking certain symbols on the reels. Re-spins can either be triggered by the appearance of certain symbols on the reels or won in the form of a bonus round. However, how beneficial the re-spin feature actually is depends on the specific slot and its paytable.
