Hot Sync slot review

Hot Sync slot: the short version

Hot Sync takes the look of a classic fruit machine and adds a modern respin feature. It sits on a standard 5×3 grid with 20 paylines, which makes it one of the more readable high-volatility games on a phone.

Quickspin, the studio behind it, started in Stockholm in the early 2010s and has been owned by Playtech since May 2016. It holds Gambling Commission account 38516 and has about 150 video slots, with Big Bad Wolf and Sakura Fortune among its best known. See our Quickspin slots page for more.

How the features work in Hot Sync

The game has two features, and they link together. The respin is the engine; the free spins give it more chances to run.

The Hot Sync Respin, step by step

1. On a paid spin, two or more Hot Sync wilds land at the same time.
2. The reels holding those wilds turn hot.
3. Hot reels gain extra wilds, and the reels respin.
4. If more Hot Sync wilds land, the respins continue.
5. The sequence ends when a respin brings no new Hot Sync wilds.

The key point is that one Hot Sync wild on its own does nothing special. You need at least two together. Once the sequence starts, its length depends entirely on whether new Hot Sync wilds keep appearing.

Free spins

Scatters landing on reels 2, 3 and 4 award eight free spins. The Hot Sync Respin can still trigger during those spins, so the round is effectively eight extra chances at the main feature without staking more.

Hot Sync RTP: what “default” means

The listed figure, 96.29%, is the game’s default RTP. Many studios also supply lower settings that a casino can choose, so “default” is a hint that other versions may exist. Apps do not have lower RTP by default, but individual casinos can pick a different setting for a game.

The Gambling Commission’s rules on game descriptions and the likelihood of winning (RTS 3) (opens in a new tab) require game information to be available before you play, and our page on RTP information rules explains what that means in practice. In short, the game’s help screen should tell you which RTP applies. If it says 96.29%, you are on the default.

What £20 buys on the Hot Sync slot

At 96.29%, the house edge is 3.71%. Multiply that by your stake to get the average cost per spin. It is an average over a huge number of spins: a single session on a high-volatility game can finish well above or below it.

High volatility shows up in how the session feels. Much of the game’s value depends on two Hot Sync wilds landing together and then on the respins continuing, so you may go many spins with little coming back. At £1, twenty such spins end a £20 session. At 10p, the same budget covers ten times as many attempts.

An hour on Hot Sync

UK rules mean at least 2.5 seconds per spin. If you averaged one spin every five seconds, that would be 720 spins an hour. At 50p a spin, you would stake £360 and the average cost would be about £13.36. That figure is the reason many players set a reality check as well as a deposit limit.

Hot Sync max win: not published

We could not confirm a maximum win figure for Hot Sync from a reliable source, so we have not quoted one. The in-game paytable shows what each symbol pays, and the rules screen should state any cap.

Without a published ceiling, the volatility rating is your best guide to risk. High volatility means returns are uneven: occasional larger results and long spells of small ones. That is enough to plan a sensible stake, which matters more than any headline number.

Playing Hot Sync on iPhone and Android

Hot Sync is a 2017 game built for browsers, so it runs in HTML5 inside casino apps and mobile browsers. Quickspin does not publish whether it is designed for portrait or landscape. A 5×3 fruit grid is easy to follow at phone size, and the hot reels make it clear when the respin is running.

• Get casino apps only from the official App Store or Google Play listing. Our guides cover iPhone and Android.
• Check the lobby: we cannot confirm which apps carry Hot Sync, so search for it by name.
• Open the paytable before playing to see symbol values and any win cap.
• Use a stable connection for longer respin sequences; results are stored on the server if your signal drops. Our page on casino app data usage has more.

To try the game without staking, many apps offer a demo mode, but UK rules still require age verification first. Our guide to demo mode on casino apps explains how it works.

UK rules that apply to Hot Sync

Hot Sync was released before the UK tightened its online slot rules, so British versions run under newer limits than the game launched with.

The stake caps are explained in the Commission’s online slots stake limit guidance (opens in a new tab) and on our slot stake limits page. The speed rules are on our page about why slots spin slower on UK apps.

Hot Sync vs other Quickspin slots

Quickspin’s best-known games take a different line from Hot Sync. Here is how they compare on published figures.

Big Bad Wolf has the higher published RTP and medium volatility, so it suits steadier play. Sakura Fortune shows how wide RTP versions can be, which is a good reminder to check the help screen. For another compact grid, see Fire Joker (3 reels × 3 rows, 5 paylines) or browse our full slots hub.
