In your online slots, reel respins are one of the most popular features. This is because they allow players to win big without spending money. The most common way to trigger reel respins is by landing a specific combination of symbols on the reels. For example, some slots require players to land three or more scatter symbols to trigger a respin. Once triggered, the player will have another chance to land a winning combination and earn a payout. In some cases, the player may even be able to re-trigger the respin feature and have another chance at winning. While reel respins can be very lucrative, they are also risky. This is because there is no guarantee that the player will land a winning combination on their second try. However, if luck is on their side, they could walk away with a huge payout!
