Respins Slots (2137+ Games)

First look at Respins

Respins hold one or more symbols in place and re-spin the remaining reels, giving you an extra shot at a win without a new bet. Some studios brand the same idea as Hold and Win, Lock and Spin or Sticky Respins, so the label shifts but the maths stays close.

The mechanic went mainstream around the mid-2010s and now anchors 2137 titles from Play'n GO, Pragmatic Play and Microgaming. What I keep noticing is how central the round has become: on many of these games the published 96% figure hinges almost entirely on this round rather than the base spins.

How the mechanic works

A trigger, usually a Scatter or a filled reel, locks the qualifying symbols and awards a set of re-spins. Each fresh landing resets the counter, so the round extends until the reels stall. On Big Bass Bonanza and similar titles the retrigger loop drives the bulk of the payout, and the return leaks slightly when the retrigger fails to land.

Respins and RTP

On paper the feature accounts for the bulk of the payback. Strip out the bonus and the base game RTP drops to a thin slice, because the base spins hold only a fraction of the total return. The RTP breakdown splits cleanly between base and bonus, with the theoretical return climbing sharply once the round fires at its natural rate.

I always check whether a game offers a buy option, since where permitted the buy shifts the RTP to a different figure, sometimes higher, sometimes lower. A higher hit rate trades against a lower per-hit contribution, so frequent small locks rarely match the punch of a rare full-board fill. The certified return assumes the feature fires at its natural rate, not the buy.

Standout slots to test

Money Train 3 from Relax Gaming pushes the Respins ceiling hard, with a max win near 100,000x and an RTP around 96.2%. Fire in the Hole 2 pairs a collapsing grid with locking symbols and a similar top exit. For steadier pacing I rate Book of Ra Deluxe style locks less, and prefer the crisper Big Bass Splash.

Wolf Gold from Pragmatic Play keeps its Money Respin round simple and reliable, sitting at 96.01% RTP. Rise of Olympus by Play'n GO and Dead or Alive 2 round out the shortlist. The category average max win of roughly 8,761x is a loose guide only, given how wide the spread runs between these titles.
