Booming Games mobile slots are mostly coin-collecting Hold and Win games from a Malta-based studio licensed in Great Britain, and they run inside UK casino apps on iPhone and Android with British rules applied. Here is how the respin rounds work on a small screen, what the Boost+ option does to the cost of each spin, and how to track the games down in a lobby.
Booming Games is based in Birkirkara, Malta, and holds a Gambling Commission licence (account 57254).
Its signature is the Hold and Win series: land six or more coin-style symbols to start three resetting respins.
Boost+ is an optional stake increase, so check the total cost per spin and remember the £5 (25+) and £2 (18–24) caps.
Bonus buy options seen in overseas versions are not offered to players in Great Britain.

Who Booming Games is
Booming Games is a slot developer with its registered office in Birkirkara, Malta. Company announcements describe it as founded in 2014 and licensed in Malta, Great Britain and Sweden. Its Malta Gaming Authority B2B licence (MGA/B2B/459/2018) was issued on 10 September 2018, and it appears on the Gambling Commission register under account number 57254, which is what allows British casinos to offer its games.
The studio says it employs more than 200 people from 45 nationalities and releases roughly four games a month. That pace means a lobby can hold dozens of Booming titles, many of them variations on the same core idea: coins land, lock in place and pay out in a respin round. If you like that format, the catalogue is deep; if you prefer story-driven bonus rounds, it can feel repetitive.
Like any supplier, Booming provides the game software and maths. The UK casino whose app you use holds your money, applies your deposit limits and handles verification and withdrawals.
How Booming Games Hold and Win slots work on mobile
The Hold and Win mechanic is the backbone of the catalogue. Most Booming releases follow a pattern you can learn once and recognise everywhere.
In the base game, coin-style symbols carrying cash values land on the reels alongside ordinary symbols.
Six or more of them on one spin triggers the feature, and the reels clear except for those symbols.
You get three respins. Each new coin that lands sticks and resets the counter to three.
The round ends when a respin passes with no new coin, or when every position is filled.
All the values on screen are added up and paid; filling the whole grid usually awards the top fixed prize.
A worked example: at a 20p stake, imagine the round ends with eight coins worth 1x, 1x, 2x, 2x, 3x, 5x, 1x and 10x your bet. That totals 25x, or £5. Most rounds end well short of a full grid, and many spins between features return nothing at all, which is why these games feel quiet for long stretches. Our page on Hold and Win slots apps compares the format across studios.
Recent Booming Games slots and their published figures
The figures below come from the studio’s own launch announcements. Your app’s version may differ, so check the info screen inside the game before relying on any of them.

Each of these also has a separate free spins round triggered by scatter or bonus symbols. In Greedy for Gold, three, four or five scatters award 10, 15 or 20 free spins, and jumbo symbols can land on the middle reels. In Blazing Bullets, wilds expand to fill whole reels during free spins. Other Booming titles you may see include Buffalo Hold and Win, Tasty Bonanza and Vegas Pig 2.
Boost+: what it does to the cost of each spin
Boost+ is an optional switch that raises your stake in exchange for a better chance of triggering bonus features. Booming’s announcements describe different increases for different games, for example 25% on Greedy for Gold and 1.5 times the bet on Blazing Bullets, so the toggle in each game tells you the real figure.

More features does not mean more money back overall: you are paying more per spin for them. The boosted total is your real stake and counts towards the UK limit of £5 per spin for players aged 25 and over, or £2 for those aged 18–24. If you use it, lower the base stake so the boosted figure fits your budget. The same logic applies to the ante bet in other studios’ games.
Overseas versions of these games sell bonus rounds for 75x or 100x the bet. That option is removed for players in Great Britain, and whether Boost+ itself appears depends on the version your casino runs.
What a Booming respin round looks like on a phone
Booming’s 5x3 layouts suit a phone held upright: the grid sits in the middle, the jackpot labels (Mini, Major, Grand) run across the top, and the stake, balance and win strip sits below with the spin button in thumb reach.
Respin counter. A small number, usually above or beside the grid, shows how many respins remain. It jumps back to three each time a coin lands.
Coin values. Each coin displays its value as a multiple of your stake or as a cash amount. On smaller screens these can be hard to read, so the running total underneath is the better guide.
Collector symbols. Some games add a pot or character that gathers coins during normal play; a progress meter fills as it collects.
Feature summary. At the end of the round a panel totals the win; tap to continue rather than waiting.
LivePlay Slots: why you won’t find them in UK apps
Booming has teamed up with Live Play Mobile on LivePlay Slots, a format in which a live host presents slot play to a shared audience. It launched on Modo Casino, a social gold-coin site, with live-hosted versions of titles such as Buffalo Hold and Win and Tasty Bonanza. The partners describe it as available only in eligible jurisdictions.
That product is aimed at social and sweepstakes-style markets, not at British real-money casinos, so do not expect to see it in a UK app. The standard Booming slots are what British casinos carry. If you are interested in hosted formats that are offered here, look at game show apps, which run under the live casino rules rather than slot rules.
RTP and volatility in Booming Games slots
Many slots are released in several RTP versions, and the casino chooses which to run, so the only figure that applies to you is in the game’s help screen. Open the game, tap the menu or info icon and scroll to the return-to-player line.
Hold and Win games concentrate much of their value in the respin feature and the fixed prizes, which tends to make them swingy. On £50 of stakes you might see a feature early and finish ahead, or go through the lot without one. A 96% RTP means £48 back on average over a vast number of plays, not in your session. Set a budget you are happy to lose and stop when it is gone; our guide to bankroll management on mobile explains simple ways to do that.
UK rules applied to Booming Games slots
No autoplay: each spin, including each paid base spin, needs its own tap. Respins inside a feature play automatically because they are part of one result.
Each spin lasts at least 2.5 seconds, with no turbo or slam-stop.
No bonus buy for players in Great Britain.
Stake limits of £5 per spin (25 and over) and £2 per spin (18–24), including any Boost+ increase.
Wins smaller than your stake are not celebrated with win sounds or animations.

How to find Booming Games titles in a casino app
Open the app and sign in.
Go to Slots or Casino from the bottom menu.
Open the provider filter and look for Booming or Booming Games.
If there is no filter, search for Hold and Win, which brings up most of the series.
Open a game and check the info screen for the RTP and whether Boost+ is present.
Some apps group these games in a Hold and Win or Jackpots category instead. Not every UK casino carries Booming, so confirm before you deposit.

Frequently asked questions
Is Booming Games licensed in the UK?
Yes. Booming Games appears on the Gambling Commission’s public register under account number 57254, and it also holds a Malta Gaming Authority B2B licence issued in 2018. A supplier licence lets British casinos offer its games, but your account, money and protections sit with the casino, which needs its own licence. You can search any company on the register by name or account number; our guide to checking a casino licence shows how to do it from your phone.
What is a Hold and Win slot?
A Hold and Win slot is one where special coin-style symbols lock in place and trigger a round of respins. In Booming’s games, six or more coins usually start the feature with three respins, and every new coin resets the counter to three. When the respins run out, the values on screen are added together and paid, and filling every position normally awards the largest fixed prize. The feature is where most of the value sits, so base-game spins often return little. Our Hold and Win glossary entry explains more.
What does Boost+ do in Booming Games slots?
Boost+ is an optional switch that increases your stake in return for a higher chance of triggering bonus features. Launch announcements have described increases of 25% on one game and 1.5 times the bet on another, so read the figure in the game itself. It does not improve the long-run return; you are simply paying more for each spin. The boosted amount counts towards the UK stake limits. Our guide to max bet rules explains why it also matters if you are playing with a bonus.
Can I buy the bonus in Booming Games slots?
Not in Great Britain. Versions of Booming games played elsewhere offer a Mystery Bonus or Super Bonus that you can buy for 75x or 100x the stake, but bonus buy is not offered to players in Great Britain on any studio’s games. In a UK app, the Hold and Win feature and free spins can only be triggered through normal play. If a video shows a buy button, it was recorded in another market. See our bonus buy page for the background to the rule.
Are LivePlay Slots available in UK casino apps?
No. LivePlay Slots, the live-hosted format Booming developed with Live Play Mobile, launched on a social gold-coin casino and is described as available only in eligible jurisdictions. It is not part of what British real-money casinos offer. In UK apps you will find Booming’s standard slots, which you play on your own. If you want a hosted experience, live game shows are available in many UK apps and follow live casino rules. Our page on live casino apps explains what is on offer.
Do Booming Games slots work on iPhone and Android?
Yes. Booming builds its games in HTML5, so the same version loads in a casino’s iPhone app, its Android app or a mobile browser. There is no separate Booming download; you open the casino’s app and launch the game from the lobby. Older phones can struggle with long respin rounds, so close other apps if animations stutter. Whether you can play a particular title depends on the casino’s selection, not on your device. Our page on mobile slots in the UK covers the basics.
What is the biggest win on a Booming Games slot?
It depends on the game, and the published maximum is a cap, not a likely outcome. Recent releases list figures such as 2,000x the stake for Gold and Glamour Hold and Win and Greedy for Gold, and 2,300x for Blazing Bullets, with a Grand fixed prize of up to 1,000x. At a 20p stake, 2,000x is £400. Reaching the cap is very rare. Check the paytable in your app for the current figure, and read our guide to max win for how these caps work.
How fast can I spin on a Booming Games slot in the UK?
No faster than one spin every 2.5 seconds. That minimum applies to every online slot offered in Great Britain, and turbo or quick-stop buttons are not available. Autoplay is banned too, so each paid spin needs its own tap. Respins inside a Hold and Win feature play out automatically because they are part of a single feature result. These rules exist to slow play and help you keep track of spending. The autoplay glossary entry explains the history of the ban.
Why can’t I find Booming Games in my casino app?
The most likely reason is that the casino does not carry the studio. Each operator chooses which suppliers to offer, and lobbies change over time. Try the provider filter, then search for Hold and Win or a game name such as Gold and Glamour. If nothing appears, the games are not available in that app. A missing tile can also mean the app needs updating, so check the App Store or Google Play. Search tricks for common lobby layouts are in finding games in a casino app.
