A nudge feature in slot games allows players to slightly shift reels to enhance their chances of forming winning combinations. When activated, it typically lets players nudge one or more reels down by one position, rather than spinning them again. This feature enhances player engagement by giving them a sense of control and increasing the excitement of gameplay, as it can help secure wins or trigger bonus rounds. It adds a strategic layer to the experience, allowing players to influence the outcome more directly than in standard spins.
