Hot Sync slot: the short answer
Hot Sync looks like a traditional fruit slot, with familiar fruit symbols on a five-reel, three-row grid, but it plays like a modern feature game. Quickspin, the Stockholm studio owned by Playtech since May 2016, built it around one idea: when wilds line up in sync, they take over their reels and the game keeps respinning. That makes it a slot of streaks, where most spins pay little and the occasional chain of respins does the heavy lifting.
Anyone browsing our slot reviews for a straightforward fruit game should know that this is not a gentle, low-variance title. It is rated high volatility, so it suits players who accept that a session can end with nothing to show for it in exchange for the chance of a bigger respin run.

The word default next to the RTP matters. Many studios supply a game at more than one return setting, and the operator chooses which to run. 96.29% is the standard version; a casino could run a lower one. The figure on the game's help screen is the one that applies where you play, so open it before your first spin. Our explainer on why some slots have different RTPs at different casinos covers how that works.
How the features work: Hot Sync Respin and free spins
Hot Sync wilds
The game has special Hot Sync wild symbols. One on its own behaves as a wild. The feature starts when two or more of them land on the same spin.
The Hot Sync Respin
With two or more Hot Sync wilds showing, the reels they sit on turn hot. Hot reels gain extra wilds, and the game gives a respin. If another Hot Sync wild lands during that respin, the sequence continues; respins keep coming until a spin produces no further Hot Sync wilds. Each extra wild means more reel positions that can complete line wins, so a long chain can build a sizeable payout from what started as an ordinary spin.
Keep the sequence in proportion. The respin chain is part of the paid spin that set it off, and its average value is already included in the RTP. It is not extra value on top of the game's maths, just the place where much of that return is concentrated.
Eight free spins
Scatter symbols appear on reels 2, 3 and 4 only. Landing them there awards eight free spins, and during the round the Hot Sync Respin can still trigger. That overlap is the game's high point: a respin chain inside a free spin costs nothing extra and can repeat across the eight spins. Our checked data does not list any extra multiplier or upgrade in the round, so read the paytable rather than expecting one.
Hot Sync RTP and high volatility on a £20 budget
At the default 96.29% RTP the house edge is 3.71%. That gives an average cost per spin of your stake multiplied by 0.0371. The table shows what that means for three common stakes.
| Stake | Spins from £20 with no wins | Average cost per spin | Average cost per 100 spins |
|---|---|---|---|
| 10p | 200 | 0.37p | 37.1p |
| 50p | 40 | 1.86p | £1.85 |
| £1.00 | 20 | 3.71p | £3.71 |
The averages look small, but high volatility changes how they arrive. A high-volatility game pays a large share of its return through features, so a typical session swings well away from the average in both directions. With £20 at £1 a spin, a run of 20 losing spins ends the session before the respin has a fair chance to appear. Dropping to 10p gives 200 spins of runway at the same budget, which is a more realistic way to see how this game behaves.
A worked example: at 20p a spin, 500 spins puts £100 through the game, and the average loss is £3.71. Two players doing exactly that could easily finish £20 down and £40 up. Our slot volatility guide and the risk of ruin page explain why stake size matters so much on games like this.
Respins are not autoplay: UK rules on Hot Sync
A common question is whether a chain of respins breaks the UK ban on autoplay. It does not. Autoplay means the game placing new paid spins for you; a respin is a feature inside one paid game cycle. The Gambling Commission's responsible product design standard (RTS 14) (opens in a new tab) bans autoplay, turbo and slam-stop on slots, sets a minimum of 2.5 seconds per spin, and stops games celebrating a return that is not more than the stake. Read more on our autoplay ban page.
Stake limits also apply: £5 a spin for players aged 25 and over since 9 April 2025, and £2 for 18 to 24-year-olds since 21 May 2025, as the government's announcement of the £2 limit for under-25s (opens in a new tab) confirms. Since the Gambling Commission's January 2020 warning, British players have not been offered feature buy-ins, so the free spins can only be reached through the scatters.
How to play Hot Sync step by step
- Open the help screen and confirm which RTP version the casino runs.
- Decide a session budget and a stop point before your first spin.
- Pick a stake; all 20 paylines are active on every spin.
- Spin manually; each paid spin needs its own press in the UK.
- Watch for two or more Hot Sync wilds, which start the respin chain automatically.
- Land scatters on reels 2, 3 and 4 for eight free spins.
- Check the net position shown on screen and stop at your limit.
Hot Sync myths that cost money
- "One Hot Sync wild means two are coming." Each spin is independent; a near miss carries no information.
- "The respin is overdue after a long dry spell." Slots have no memory, as our page on whether slots can be due a win explains.
- "Bigger stakes trigger features more." The feature chance is the same at every stake; only the size of wins changes.
- "Fruit symbols mean a simple, low-risk game." Theme says nothing about volatility; Hot Sync is rated high.
Hot Sync against other Quickspin slots
Quickspin's catalogue runs to about 150 video slots. If Hot Sync's swings feel too steep, Big Bad Wolf is rated medium volatility with a 97.34% RTP. Sticky Bandits and Dwarfs Gone Wild sit at medium-high. Compare them below.
| Slot | RTP | Volatility | Paylines |
|---|---|---|---|
| Hot Sync | 96.29% (default) | High | 20 |
| Big Bad Wolf | 97.34% | Medium | 25 |
| Sticky Bandits | 96.58% (default) | Medium-high | 30 fixed |
| Dwarfs Gone Wild | 96.38% | Medium–high | 20 |

Frequently asked questions
What is the RTP of the Hot Sync slot?
Hot Sync has a default RTP of 96.29%, so the average cost is about 3.7p for every £1 staked over the long run. Because it is a default figure, an operator may run a lower version, so confirm the number on the game's help screen. Our RTP explained page shows how return to player is calculated and why it only settles down over very large numbers of spins.
How does the Hot Sync Respin work?
It starts when two or more Hot Sync wilds land on one spin. Their reels turn hot and gain extra wilds, and the game respins. Further Hot Sync wilds keep the chain going, and it ends on the first respin with no new ones. All of this happens within the paid spin that started it. Our respins feature guide compares this with respin mechanics in other slots.
How many free spins can you get on Hot Sync?
The free spins round gives eight free spins, triggered by scatters on reels 2, 3 and 4. The Hot Sync Respin can still trigger during those spins, which is where the game's biggest results tend to come from. Our checked data does not list an extra multiplier in the round, so read the paytable. The scatter symbols page explains how scatter triggers differ from line wins.
Is Hot Sync a high volatility slot?
Yes, Hot Sync is rated high volatility. Most of its return comes through the respin chain and the free spins, so ordinary spins often pay little or nothing. That makes results swing widely over a short session. If you want a steadier fruit game, look at our fruit slots collection, which shows the volatility of each title so you can choose a calmer one.
Who makes Hot Sync?
Hot Sync is made by Quickspin, a Swedish studio founded in Stockholm in the early 2010s and owned by Playtech since May 2016. Quickspin holds a Great Britain licence (Gambling Commission account 38516) and has about 150 video slots. It is best known for Big Bad Wolf and Sakura Fortune. See our Quickspin slots page for the studio's other games.
Does a respin chain count as autoplay?
No, a respin chain is a feature inside one paid spin, not autoplay. UK rules ban the game from placing new paid spins on its own, but bonus features that need no extra stake can run automatically. Each new paid spin on Hot Sync still needs you to press the button. Our game design rules page sets out what changed for UK slots in October 2021.
What stake should I use on Hot Sync with £20?
A low stake such as 10p or 20p gives you the most spins from £20, which matters on a high-volatility game. At 10p, £20 covers 200 spins before any wins; at £1, only 20. The RTP is identical at every stake, so a lower stake does not change the odds, it just stretches the session. Our bankroll management guide helps set limits.
Can you buy the free spins on Hot Sync in the UK?
No. Feature buy-ins are not offered to British players, following a Gambling Commission warning in January 2020, so the only way into the free spins is landing the scatters. That keeps every player on the same base-game route to the round. Our page on feature buy rules in the UK explains the background to that warning.
