Play’n GO mobile slots are a fixture of UK casino apps, led by Book of Dead and the Rich Wilde adventure series. This page explains who the independent Swedish studio is, how its book slots and grid games play on a phone screen, why its RTP settings deserve a closer look than most, and how to find its titles in a licensed app.
Play’n GO is an independent, privately held studio based in Växjö, Sweden, whose first gaming product dates from 1997.
It holds a Gambling Commission licence (account 55949) and says it supplies more than 350 games in 30+ jurisdictions.
Book of Dead, Legacy of Dead and Reactoonz are its best-known slots; many games share the Rich Wilde character.
Play’n GO games come in several RTP settings, so check the game rules in your app before you play.

Play’n GO in brief: an independent Swedish studio
Play’n GO traces its first gaming product back to 1997 and is based in Växjö in southern Sweden. Unlike many of the big names in this section, it has stayed independent and privately held rather than joining a larger group. Its website states that it holds a Gambling Commission licence under account number 55949, alongside licences in Malta and Gibraltar, and describes a catalogue of more than 350 games supplied in over 30 jurisdictions.
Two things define the studio for a mobile player. The first is a consistent visual style, with games that look and behave like part of one family. The second is a shared cast of characters, led by the explorer Rich Wilde, that links dozens of titles. If you enjoy one Play’n GO game, the controls and menus of the next will feel instantly familiar.
Rich Wilde and the book slots on mobile
Book of Dead is the title most people associate with Play’n GO. It uses a 5x3 grid with 10 paylines and a published top RTP of 96.21%. Three or more book symbols start free spins, and before they begin one symbol is chosen at random to act as a special expanding symbol. Whenever enough of that symbol lands during the feature, it grows to fill whole reels and pays across all lines, which is where the 5,000x maximum comes from.
That expanding-symbol idea has been copied so widely that book slots are now a genre of their own. Play’n GO reused it in Legacy of Dead, which can add extra expanding symbols when free spins retrigger, and in Rise of Merlin. On a phone, the book format suits portrait play well: three rows of large symbols, ten fixed lines, and one big moment to watch for.
Other Rich Wilde adventures
The character also appears in grid-based games such as Tome of Madness, a 5x5 cluster-pays slot with a 2,000x published maximum. Playing these one after another makes a useful lesson in how much the maths can change under the same branding: identical artwork does not mean identical risk.
Grid games: Reactoonz, Moon Princess and Viking Runecraft
Play’n GO’s second big family is built on large square grids where groups of touching symbols win and then clear. Reactoonz is the best known, with a 7x7 grid, cluster pays for five or more connected symbols and a charge meter that powers up special features as wins build.
Grids like this are made for an upright phone. A square layout uses the width of the screen without letterboxing, and the action happens in one block rather than across a wide reel set. The downside is pace: a long chain of clearing symbols can take several seconds, and it is easy to lose track of the stake when the animations are busy. Keep an eye on the balance line at the bottom between rounds.

Most of the catalogue sits at high volatility. Fire Joker and Gemix are the main medium-volatility exceptions here, and Fire Joker’s 3x3 layout is about as simple as a modern slot gets on a small screen.
Play’n GO RTP settings: why you should always check
Every figure in the table above is the top version. Play’n GO, like other studios, lets casinos choose from several RTP settings for the same game, and the slot facts we hold note that lower versions exist for titles such as Gemix, Honey Rush and Viking Runecraft. The artwork, features and maximum win stay the same; only the long-run return changes.
Here is why it matters. Suppose you stake 50p a spin for 400 spins, a total of £200. At 96.21% the theoretical return is about £192, an average cost of £8. If a casino ran a version three percentage points lower, the average cost over the same stakes would rise to about £14. Neither figure predicts a single session, but over months of play the setting adds up. Our RTP range glossary entry explains the idea.
Open the Play’n GO game and wait for it to load fully.
Tap the menu icon, usually three lines in a corner of the screen.
Choose the information or rules option.
Scroll until you see the theoretical return to player.
If the figure is noticeably below the top RTP, decide whether to play there or elsewhere.
How Play’n GO games handle a small screen
Play’n GO uses a consistent control layout across its games, which helps on a phone. The spin button sits in a fixed position, the stake selector opens as a separate panel, and the paytable is split into swipeable pages rather than one long scroll. Wins are shown as a figure in a bar under the reels, along with your balance.
Book slots and other 5x3 games resize neatly to portrait, with the reels filling the upper half of the screen.
Grid games stay square, so they look the same whichever way you hold the phone.
Paytables use symbols rather than long text, which makes them readable even on a compact phone like the iPhone SE.
Sound and effects can be toggled from the menu if you are playing somewhere quiet.
UK rules in Play’n GO games
Play’n GO games supplied to Britain follow the same rules as every other online slot here. There is no autoplay or turbo, every spin takes at least 2.5 seconds, and the stake panel stops at £5 per spin for players aged 25 and over or £2 for those aged 18 to 24. Wins smaller than your stake are not presented as wins, and your net position for the session is shown.
Some book-style slots offer an optional gamble feature after a win, where you guess a card colour or suit to double or quadruple the amount. If your version shows it, skip it: it adds risk to money you have already won. Free-play demos are available only once your age is verified. For the full list of changes, see UK slot design rules on mobile.
Finding Play’n GO mobile slots in a casino app
Open the casino app and go to the slots lobby.
Tap Filter or Providers and pick Play’n GO, if the app offers a studio filter.
Alternatively, search for Book of Dead or Reactoonz and open the game.
Look for a More from this provider row under the game, which some apps show.
Star the titles you want to keep so they appear in your favourites.
Search sometimes struggles with the apostrophe in the studio’s name; typing playngo or play n go often works better. Our guide to finding games in a casino app has more shortcuts.

Frequently asked questions
Is Play’n GO licensed in the UK?
Yes, Play’n GO states on its website that it is licensed and regulated by the Gambling Commission under account number 55949. It also lists licences from the Malta Gaming Authority and the Gibraltar regulator. A supplier licence covers the games themselves, while the casino you play at needs its own operator licence. Both can be checked on the Commission’s public register in a few taps. Our guide on how to check a casino licence shows the steps on a phone.
What is the most popular Play’n GO slot?
Book of Dead is the Play’n GO slot most players know, and it appears in a large share of UK casino lobbies. It is a high-volatility 5x3 game with 10 paylines, a published top RTP of 96.21% and a maximum win of 5,000x. Its free spins use a randomly chosen expanding symbol, which creates the big moments the game is known for. Reactoonz and Legacy of Dead are other strong contenders. Our Book of Dead guide explains each feature for phone players.
Who is Rich Wilde in Play’n GO games?
Rich Wilde is Play’n GO’s recurring adventurer, an explorer character who appears in a series of treasure-hunting slots. He first became widely known through Book of Dead and has since featured in titles such as Tome of Madness. The character links the games visually but not mathematically, so two Rich Wilde slots can have very different layouts, volatility and maximum wins. Read each paytable rather than assuming the rules carry over. Our page on book slots in apps covers the format he is best known for.
Why is the RTP of Book of Dead lower in some casino apps?
The RTP can be lower because Play’n GO supplies Book of Dead in several settings, and each casino chooses which to run. The published top figure is 96.21%, but versions with lower returns exist. Everything you see on screen is identical, so the only way to tell is to read the game rules inside the app, where the theoretical RTP is printed. Over a long period, a lower setting means a higher average cost. Our guide to finding a slot’s RTP walks through the menus.
Do Play’n GO slots work better in portrait or landscape?
Most Play’n GO slots work well in portrait, especially the square grid games such as Reactoonz and Viking Runecraft, which fit an upright screen naturally. Five-reel book slots also resize to portrait, with the reels across the top and the controls below. Landscape gives slightly larger symbols on a 5x3 game, which some players prefer on a small phone. The outcome of each spin is the same either way. Our guide to portrait versus landscape slots compares the two.
Can I play Book of Dead for free on my phone in the UK?
You can play a free demo of Book of Dead in some UK apps, but only after your age has been verified. Licensed casinos have had to confirm players are 18 or over before offering free-to-play games since 2019. Once verified, look for a Demo or Play for Fun button on the game tile. Demo credits cannot be withdrawn, and some casinos do not offer demos at all. Our demo mode glossary entry explains what changes between free and real-money play.
Are Play’n GO slots suitable for low stakes?
Yes, Play’n GO slots usually let you start from small stakes, often a few pence per spin, though the exact minimum depends on the game and the casino. Low stakes reduce how fast a balance moves, but they do not change the RTP or the house edge. Bear in mind that most of the studio’s popular games are high volatility, so even at low stakes long losing runs are normal. Our page on penny slots apps covers low-stake play in more detail.
Why can’t I search for Play’n GO in my casino app?
The apostrophe in Play’n GO often confuses in-app search, because some apps treat it as a special character. Try typing playngo or play n go, or search for a game title such as Reactoonz instead. If the app has a Providers filter, the studio will usually be listed there. If nothing appears at all, that casino may not carry Play’n GO games. Our casino app glossary and lobby guides explain other filters worth knowing.
