Play'n GO: Book of Dead, and the question of which version you're playing

Published September 24, 2026

A studio from a small Swedish city

Play'n GO traces its roots to 1997 in Växjö, a university town in southern Sweden, and has used the Play'n GO name since 2005. That makes it one of the oldest studios still putting out new slots every month, older than Pragmatic Play by nearly two decades.

For years it built everything in-house, including the platform its games run on. It shows in the catalogue: a consistent look, interfaces that barely change from one game to the next, and a habit of turning a hit into a family of sequels.

Rich Wilde and the book slot

Book of Dead came out in 2016 and is still the game people picture when they hear Play'n GO. Five reels, three rows, ten lines. During free spins one symbol is chosen at random and expands to fill whole reels. That single idea carries the whole game, and the top version returns a published 96.21% with a maximum win of 5,000×.

Its explorer, Rich Wilde, headlines a series: Aztec Idols came first, then Book of Dead, Pearls of India, Tome of Madness and more. If you enjoy one, the others will feel familiar within a few spins.

One honest warning about book slots: the base game is thin. Ten lines rarely pay much, so most of the return is locked inside the free spins, and the choice of the expanding symbol decides almost everything. A bonus with a low-paying card symbol expanding can return less than you spent reaching it. Budget for that outcome instead of hoping it won't happen.

Not just books

• Reactoonz (2017): a 7×7 grid of alien blobs that pay in clusters. Published RTP 96.51%.
• Legacy of Dead: the book mechanic again, in a newer frame.
• Moon Princess and Rise of Olympus: grid games with character powers.
• Fire Joker: a three-reel game for players who want quick, simple rounds.

The version question, with real dollars

This is where Play'n GO deserves your attention. The studio offers many of its games at several RTP settings, and some sit well below 90%. The casino picks one. Same artwork, same sounds, same Rich Wilde; different price.

To show what that means, here is 1,000 spins of Book of Dead at $0.50, or $500 played through, at three settings of the kind Play'n GO makes available. The settings below are illustrative, not a list of what any casino runs.

Twenty-five dollars on one evening is a nice dinner out. Across a winter of Friday nights, it becomes real money, and you get nothing extra for it.

How to find the version you're on

1. Load the game, in real-money mode if possible, since demo modes can differ.
2. Open the menu (the three lines or the i button) and go to the game rules.
3. Scroll to the section on return to player. Play'n GO prints the theoretical RTP there.
4. Compare it with 96.21% for Book of Dead, or the top figure for whichever game you chose.
5. If it is several points lower, play something else at that casino, or play it elsewhere.

Would you buy the same box of cereal at a store that charged a third more for it? That is the decision the rules screen is quietly asking you to make.

Where Play'n GO feels dated, and where it doesn't

Next to a Hacksaw or Nolimit City release, a ten-line Play'n GO game can feel slow. There is no bonus buy on many older titles, no cascade of multipliers, and base-game wins are small. That is also the appeal: you can follow what is happening, and a $20 budget at $0.20 lasts. For more on pace and cost per hour, see our online slots guide.
