What Are Slot Re-Spins?

April 3, 2025

Many online casinos and land-based casinos offer a slot games feature called slot re-spins, or, as many players refer to them, bonus spins. A re-spin allows the player to spin the reels again and is usually done under more favourable circumstances to create a winning combination and win a prize.

Re-spins build added suspense and give players more winning chances. Sometimes, a player may be awarded more than one re-spin on a single bet. The chance of winning free re-spins keeps players interested and entertained.

How Do Slot Re-Spins Get Triggered?

Slot re-spins can be triggered during gameplay in a few common ways.

One way is by landing a special symbol or combination. Some slots will give a player re-spins when they land a special symbol (like a Bonus or Scatter symbol) or a winning combo with those special symbols. This serves as the gateway to unlocking the re-spins. Game developers often opt for special symbols or combinations, like Scatters, to activate re-spins, especially because Scatters generally pay and trigger bonus features no matter where they fall on the reels.

You can also get bonus rounds and mini-games on another screen. Some slots can use these special symbols and combinations to activate re-spins. They automatically unlock at random intervals or via specific bonus symbol combinations. Bonus rounds are usually themed and offer a fun challenge to the player, like selecting treasure chests or picking symbols that uncover instant prizes, such as cash, multipliers or re-spins.

What Happens During a Slot Re-Spin?

When re-spins are triggered, either the same reels configuration is used or an alternate set kicks in with different symbols, rows, and winning combinations in the paytable. Often, the re-spins have advantages over the base game spins. For example, some or all of the winning symbols may be held in place while the rest of the reels re-spin, making it easier to hit more wins.

Alternatively, improved symbol payouts may take effect, like higher value symbols appearing more frequently or special expanding wild symbols getting added to reels. Sometimes, persisting wilds or multipliers carry over from the triggering spin, too. Most importantly, re-spins often don’t cost anything extra to play. The player gets to benefit at no additional cost to their original wager. All these factors help boost the odds of landing a win during the re-spins.

Do Slot Re-Spins Expire?

Slot re-spins, in most cases, expire after being played through a single time. In other words, the player only gets one chance to capitalise on the free spins. If no win is scored, the re-spins end, and normal gameplay resumes.

However, some slots do offer accumulating re-spins which carry over if they continue being triggered. For example, landing re-spins during an existing set of re-spins may bank more bonus games for later. Expiring versus accumulating re-spins comes down to individual game rules and the software provider.

It’s also possible on select slots to retrigger the same re-spin scenario. As an illustration, if three Bonus symbols initially granted 10 bonus spins, then hitting three Bonus symbols again during those spins may reset the counter back to 10 for endless potential free spins. Of course, the odds of repeated triggers rely fully on luck.

Strategies for Slot Re-Spins

No playing strategies or betting adjustments will raise or lower the chances of activating slot re-spins since outcomes are randomised. Yet some general tips can help players maximise value from re-spins when they hit:

  • Check rules and paytables first to understand what features or advantages the re-spins have over regular spins. This allows for properly appraising their potential.
  • The bonus spins present free opportunities to win.
  • Slow down and savour re-spins. Take time watching the reels and build anticipation before stopping them. Draw out gameplay for more excitement.
  • Avoid getting overly indulgent and risking re-spin winnings. Consider collecting some payouts while the spins continue running.

Re-Spins vs Free Spins: What’s the Difference?

Although both versions of spins often get lumped together, re-spins and free spins are actually different mechanics. Re-spins are extra spins triggered by a specific in-game feature, usually with modifiers such as sticky symbols or locked reels. Free spins, on the other hand, are standalone features that play out over multiple rounds, usually having their own set of rules. Many modern online slot games incorporate re-spins in the base game to create quick, high-tension moments, while keeping the free spins for the main bonus feature. 

Why Knowing The Difference Matters

Keeping both mechanics separate is a good way for players to manage their expectations. Re-spins usually focus on locking in progress, for example, sticky wilds, and can reset a counter when new symbols land. Free spins tend to introduce bigger changes to the round, such as expanded reels, extra multipliers, or even new paytables over longer sequences.

Common Re-Spin Styles

Re-spins don’t all look the same. Game studios use the mechanic in lots of different ways, and each variation adds its own twist to the action. Some focus on coins that stick in place, others on wilds that expand or even walk across the reels, while a few switch things up entirely with special reel sets. 

Hold-and-Respin (Lock & Re-spin / Hold & Win)

A commonly used format where special symbols (often coins or cash-style icons) stick in place and give the player a number of re-spins. Each new special symbol that lands resets the re-spin counter. The round ends when the spins counter runs out or the grid gets filled. 

Sticky or Expanding Wild Re-Spins

Landing a wild, or a wild that expands to cover a reel, can trigger one or more re-spins with the wild positions held in place. If another wild appears during a re-spin, the feature can repeat (typically up to a set maximum amount). This style is popular in more fast-paced online slot titles where the re-spin replaces more complex bonus rounds.

Walking / Nudging Wild Re-Spins

Some games award re-spins while a special wild symbol ‘walks’ across the reels, or ‘nudges’ to expand, giving the player some extra chances when shifting wilds show up. The focus is on the wilds shifting bit by bit, with the win potential building gradually across a number of re-spins.

RTP & Volatility With Re-Spins

Re-spin features are part of a slot’s design, and while they don’t promise any returns or let players influence the outcomes, they do shape how wins play out during the session. One of the biggest effects is seen with the hit frequency. Because re-spins can hold certain symbols in place or increase the length of a sequence, they often bunch together smaller or mid-sized wins, creating short bursts of action that add extra energy compared to the base game.

Volatility plays an important role too, especially with hold-and-respins. These features tend to make the swings a little bigger, but the volatility rating of a title determines how often these moments happen in theory. 

Transparency is also important. Slots on reputable sites like PokerStars clearly explain the paytable and how re-spins work. For example, which symbols have a chance of locking in place, how the counters reset, and whether there’s a maximum number of re-spins on the feature. Understanding these stats helps the player get a feel for the rhythm of the game and understand the potential features and outcomes.

FAQs

Do re-spins always happen for free?

In most cases, yes. Re-spins are usually built into the game’s features and don’t need an extra bet beyond the spin that triggered them.

Can re-spins re-trigger?

They can, depending on how the slot has been designed. A lot of hold-and-respin titles, for example, reset the counter whenever another special symbol lands, which gives the player a few more spins to keep the round going.

Are re-spins better than free spins?

There’s no better feature, as both bring their own pros. Re-spins are quick bursts, often focusing on locked symbols or special wilds, while free spins tend to run longer and implement bigger rule changes, like new reel setups or multipliers. Many modern slots include both, letting the features work together to make a slot as fun as possible.

Do re-spins change a game’s RTP?

No, they don’t. The RTP is worked out across the entire game, and re-spins are already factored into that percentage.
