Play'n GO is the Book of Dead studio. That's the game everyone knows, and the studio's own site calls it one of the most played slots in the history of iGaming. That's their claim, not a measured fact, and it isn't our top pick anyway.
What we found when we scored fourteen of its games: the best Play'n GO slots are the cluster-pays grids, not the book games. Moon Princess, Reactoonz and Rise of Olympus all keep something happening on ordinary spins, which the line slots mostly don't.
And then there's the RTP issue. It's the most important thing on this page, so it gets its own section below. Short version: nearly every Play'n GO game exists at five RTP settings, and you won't know which one you're on unless you open the game's info screen.
Every Spin Score here uses the best published setting. Every slot also has a negative expected value at any setting.

The 10 best Play'n GO slots, ranked
Every Play'n GO slot we scored, in Spin Score order. Spin Score = 40% RTP, 15% max win, 30% free spins round, 15% base game. How we score
First place, and it earns it in both halves of the game. On the 5x5 grid, cascades raise a multiplier and three princess powers plus the Trinity respin can fire on any base spin. Clear the grid and you get free spins with a growing multiplier, where you choose the spin count and which princess helps. Max win 5,000x per bigwinboard. Top RTP is 96.5%, but bigwinboard lists four lower settings down to 84.5%. High volatility.

The best base game on the page, scored 9. On a 7x7 grid, clusters of five or more aliens pay and cascade, charging a meter that unlocks Quantum features and eventually the Gargantoon. There's no free spins round: the feature chain is the bonus, and that's what keeps it below Moon Princess. RTP 96.51% at best, down to 84.51% at the lowest setting slotcatalog lists. Max win 4,570x. Our Reactoonz guide has more.

You pick one of three gods for free spins, and that god's power fires on every non-winning spin, with a 100x prize for clearing the 5x5 grid. It's a well-built round. The max win holds it back: 2,500x per bigwinboard, lower than Moon Princess and Reactoonz. RTP ladder 96.5% to 84.5%. If you like Moon Princess, this is the closest thing in the catalogue.

Rich Wilde goes cluster pays. Clusters of four or more on a 5x5 grid charge a portal that adds Special Wilds and grid effects, and a x2 Rich Wilde wild pops up in cascades. No classic free spins. RTP 96.59%, which is the only setting bigwinboard listed; lower ones probably exist, as with the rest of the catalogue, but we couldn't confirm them. Max win 2,000x, which is the main thing dragging its score.

The highest top RTP here at 96.83%, and the only medium-volatility game in our top ten. Wins on the 7x7 grid fill a crystal charge meter that fires effects like Chain Lightning and Nova Blast. No free spins, so it scores 4 on the bonus, and that's why it isn't higher. Max win 4,513.5x. Lowest setting listed: 84.9%. A sensible pick if the high-volatility grids feel too swingy.

Same 9 for the base game as the original, with a fluctuating symbol, Electric Wilds and two meters (Fluctometer and Quantumeter) feeding Energoon and Gargantoon wilds. Max win is the highest in the catalogue at 5,083x. So why below Reactoonz? RTP. Its best setting is 96.2%, and the ladder goes down to 84.2%. Still no free spins round.

Candy cluster pays on a 5x5 grid with a Sugar Rush meter that releases features mid-spin. The free round moves to a 9x9 grid with three helper spells, and collecting two candy types opens a pick bonus. Decent, not special. Max win 3,000x, top RTP 96.5%, bottom 84.5%. I'd play Moon Princess first.

Book of Dead with a better bonus. Free spins use expanding symbols, retrigger without limit, and extra scatters give you more expanding symbols than Book of Dead does. The base game is plain 10-line spins with a wild-scatter, scored 3. That's normal for book slots, but it's dull. Max win 5,000x, top RTP 96.58%, lowest 84.55%. High volatility.

Another book-style game, tied with Legacy of Dead on every factor. Three orb scatters give eight free spins with a random expanding symbol, retriggerable, and high symbols need only two to expand. The orb wild-scatter is the only base game feature. Bets start at 0.01 per bigwinboard, the lowest in this set, which suits a small budget. RTP 96.58% down to 84.55%; max win 5,000x.

A wheel picks 3 to 20 free spins with a x2 to x10 multiplier on each spin, and two wild scatters start Pyramid Spins that keep the multiplier. It's a lottery of a bonus, which some people love. Thirty lines and stacked symbols in the base game, and little else. Max win 5,000x, RTP 96.5% at best and 84.5% at the bottom.

Play'n GO's five RTP settings, explained
This is the thing to understand before you play any Play'n GO game.
Play'n GO publishes several RTP versions of most games and the casino chooses which one to run. The figures in our records come from bigwinboard and slotcatalog, because the playngo.com game pages list no RTP at all. Of the fourteen games we scored, twelve have five settings listed. Fire Joker has two listed, and the source says lower ones exist. Tome of Madness has only its 96.59% default on record.
The ladder looks roughly the same on every game. Here's Moon Princess:
96.50%
94.51%
91.49%
87.50%
84.50%
Twelve points between the top and the bottom. Put another way: at 96.5% the long-run cost is 3.5% of what you stake, and at 84.5% it's 15.5%. That's more than four times as expensive, for exactly the same game with the same graphics and the same features. You can't tell them apart by playing.
Our Spin Score uses the best setting. At the bottom setting, every game on this page would score the minimum on RTP, because anything at 94% or below gets a 1. So the ranking holds only if the casino runs the top version.
How to check: open the game, find the paytable or the info (i) screen, and look for 'theoretical return to player' or 'RTP'. It's in the rules text, usually near the bottom. If it says 94% or lower, close it. More in our guide to RTP.
What Play'n GO is known for
Two families, really. The book and line slots (Book of Dead, Legacy of Dead, Rise of Merlin, Legacy of Egypt) are 5x3 games with a quiet base game and a single expanding-symbol or multiplier bonus. The cluster grids (Moon Princess, Reactoonz, Gemix, Sweet Alchemy, Rise of Olympus) cascade and charge meters, so the base game carries a lot more.
Volatility skews high. Eleven of the fourteen games carry a high label in our records. Only Gemix and the two Fire Joker games are medium.
Max wins sit in a narrow band: 2,000x to 5,083x for everything in our top ten, with 5,000x the most common cap. That's modest next to studios that print 50,000x or more.
On its about page, Play'n GO says it has more than 400 titles and supplies regulated operators in more than 35 jurisdictions.
How to pick among them
Do you like things happening on most spins? Take a grid: Reactoonz or Moon Princess. Would you rather sit through quiet spins for one big feature? Take a book game, and make it Legacy of Dead rather than Book of Dead.
Budget matters too. Rise of Merlin starts at 0.01 a spin per bigwinboard, which makes it the cheapest to try on small stakes. Gemix is the calmer grid.
And whichever you choose, the RTP setting at your casino matters more than the gap between any two games in this table. The whole top ten is within 0.63 points of each other at the best setting. The settings ladder is twelve points.
What to skip
Book of Dead isn't bad. It scores 6.5, the same as Big Win 777, just outside our top ten. Ten free spins with one expanding symbol, 5,000x max win, top RTP 96.21% with a ladder down to 84.18%. Legacy of Dead does the same thing with a stronger bonus and a higher top RTP. Our Book of Dead guide makes the full comparison.
Fire Joker (5.1) and Fire Joker Freeze (5.3) are 3x3 fruit games with respins and a multiplier wheel. Max wins of 800x and 1,000x. Fine for a few minutes; there's not much there.
In our table, Moon Princess, with a Spin Score of 7.9. It has a busy base game and a free spins round where you choose the number of spins and which princess helps. Reactoonz is second.
What RTP does Book of Dead have?
Bigwinboard lists five settings: 96.21%, 94.25%, 91.25%, 87.25% and 84.18%. The casino chooses which one it runs. Check the game's info screen to see which you're playing.
How do I check the RTP of a Play'n GO slot?
Open the game, then the paytable or info screen, and find the line on theoretical return to player. That figure applies to the version that casino runs. The playngo.com game pages don't list RTP, so the game itself is the place to look.
Why do Play'n GO slots have different RTPs at different casinos?
Because Play'n GO offers several RTP versions of most games and each casino chooses one. The graphics and features are identical; only the long-run return changes. A lower setting doesn't make any single spin feel different, which is why it's easy to miss.
Does Play'n GO have a bonus buy?
None of the fourteen Play'n GO games in our records lists a bonus buy among its mechanics. If you want that option, our bonus buy slots page covers the games that have it, and why we usually advise against using it.
