How Hendrix, Motorhead & Ozzy got a Second Life on a Phone Screen

There is a version of Ace of Spades that a fair few Motorhead fans have never actually heard. It is shorter, it is mixed hot, and it loops. It sits underneath a five-reel slot machine that somebody is probably playing on the bus right now, thumb going, sound off, no idea that a licensing team spent about eight months getting the master cleared.

I have been thinking about this for a while, and it is one of those small industry stories that nobody in music journalism really covers because it feels a bit grubby. But it is real, and it is a proper revenue stream, and it has been running quietly for a decade now.

The short version is this. Between roughly 2016 and today, a handful of game studios in Sweden and Malta went and licensed some of the most recognisable rock catalogues on earth, and turned them into slot games. Not parody versions. The actual recordings, the actual band logos, in a couple of cases the actual band members sitting in a studio doing new takes.

It all kicked off around 2016, sort of. NetEnt were first out properly. Jimi Hendrix landed in April 2016. Motorhead followed in the autumn of the same year. The Guns N' Roses one came out of the same wave, and then a few years later, in February 2019, NetEnt announced an Ozzy Osbourne title at the ICE trade fair in London, which is the sort of sentence you never expect to type.

Now here is the thing that surprised me when I started digging. These were not cheap cash grabs slapped together in a fortnight. The Motorhead game used real tracks. Ace of Spades, Overkill, Killed by Death. Somebody had to sit down with the estate and the label and clear all of that, and Lemmy had only died on the 28th of December 2015, so the timing was delicate to say the least.

Motorhead formed in London in 1975 and put out twenty-four studio albums before they stopped, and you can read the whole long, chaotic history of the band if you want the full picture. Twenty-four albums is a lot of masters. It is also a lot of publishing splits to untangle before a game studio can put a single riff on a loop.

Play'n GO turned it into an actual roster

If NetEnt opened the door, Play'n GO walked through it and moved in. They put out Sabaton in 2019, which was the first of what became a whole line of band titles, and they have kept going ever since. Testament arrived in March 2020. There is a KISS game built entirely around the four characters, the Starchild, the Demon, the Spaceman and the Catman. Annihilator, Twisted Sister and Saxon have all received the same treatment.

Look at that list for a second. Sabaton, Testament, Annihilator, Saxon. These are not stadium acts in 2026. These are working bands with devoted, slightly obsessive, mostly middle-aged fanbases who buy the vinyl and the hoodie and turn up in the rain in Wolverhampton. Which is exactly the point, honestly. The audience overlap is uncannily tight, and the studios clearly know it.

Twisted Sister on a slot machine is funny. Twisted Sister on a slot machine that pays the band a licensing fee every year for a catalogue they finished writing in 1984 is, when you think about it for more than five seconds, way less funny and way more sensible.

The bands are genuinely in the room for these. This was the bit that changed my mind about the whole business, actually. I assumed it was a logo rental. Send a PNG, cash the cheque, never think about it again.

With Testament it was not that at all. Play'n GO worked with the current lineup on the game, and by current lineup I mean all of them. Chuck Billy on vocals, Eric Peterson and Alex Skolnick on guitars, Gene Hoglan behind the kit, Steve Di Giorgio on bass. The studio's stated approach is to build these things alongside the artists rather than just borrowing the likeness, and you can hear the difference. The audio is mixed for the game, not lifted and squashed.

That may possibly sound like a small distinction. It isn't. A band that sits in on the mix ends up with something they will actually put on their own socials, and a band that just signs a form ends up with something they quietly hope nobody notices. The second kind is way more common across licensed media generally, so it is genuinely noticeable when a studio does the first kind.

The money bit, which is less cynical than you think. Here is where it stops being a novelty story.

In July 2021, the DCMS Committee published its report into the economics of music streaming, and the numbers in it are hard to argue with. UK streaming was bringing in over one billion pounds a year off the back of around 114 billion streams. Artists, the Committee found, could be seeing as little as 13 per cent of the income generated. MPs called for a complete reset of the market, and the case eventually went to the Competition and Markets Authority.

Thirteen per cent. Sit with that for a minute. Against that backdrop, a flat licensing fee for a game that will run for five or six years is not selling out. It is a legacy act's accountant doing basic arithmetic. A catalogue that generates rounding errors on Spotify holds the potential to generate an actual, invoiceable, predictable sum from one game deal, and unlike streaming it does not depend on an algorithm deciding your band is relevant this quarter.

Sync has always worked like this, of course. Adverts, films, video games, that awful supermarket Christmas campaign. Slots are just the newest and least glamorous member of the family. The cheque clears the same.

Where you actually run into these now. This is the part that has changed most since 2016, and it is a purely technical thing.

Back then, a branded slot meant a desktop machine and a Flash plugin and, on occasion, a download. There was no such thing as a mobile casino in any meaningful sense, not one that could stream a licensed master anyway. Now the entire thing is HTML5 and runs in a browser tab, which means the sound design is being mixed for phone speakers and cheap earbuds first and everything else second. A mobile casino lobby is basically a music delivery format at this point, whether anybody involved wants to admit that or not.

Swift Casino is one of the UK-facing sites running that way: no app, no download, just the browser doing the work. And the practical upshot for anyone curious about how these games actually sound is that you can load a demo on a phone in about four seconds and hear what a mastering engineer does when he knows the output is a two-millimetre speaker. It is a weirdly interesting listen. The compression choices alone tell you a lot.

Most people playing on a mobile casino have the sound off, which is the great irony of the whole arrangement. Millions of pounds of licensed music, muted by default, up to ninety per cent of the time. Somebody at Swift Casino or anywhere else in that market could probably tell you the exact figure, and I suspect it would ruin a few licensing executives' afternoons.

So is it selling out? I honestly don't think it is, and I have gone back and forth on this.

The argument against is obvious. Gambling is a harmful product for some people, the marketing around it is aggressive, and putting a band's name on it lends the whole thing a credibility it hasn't really earned. That is a fair position, and I am not going to talk anyone out of it.

The argument for it is that these are the same bands who sold their songs to car adverts and beer brands for thirty years and nobody wrote a think piece about it. Sabaton licensing a game about the exact historical battles they already write concept albums about is, if anything, more on brand than most sync deals ever manage.

What I would say is that the honest version matters. A game built with the band, mixed properly, with the actual masters, is a different object from a logo stuck on a generic template. Fans can tell instantly. They always can.

Anyway. Next time you are stuck in a queue somewhere, and you hear a compressed forty-second loop of something you recognise coming out of a stranger's phone, have a proper listen. There is a decent chance a publishing lawyer spent most of a year on those forty seconds. And there is an even better chance the band got paid more for it than they did for the album it came from.

Which is a bleak little sentence, but it is also just where we are.
