Since its release in February this year, Pragmatic Play's Treasures of Osiris has taken off, and no wonder. Osiris himself is right there to greet you in his gold armour, pharaoh headdress, and with his staff planted firmly beside him. He stands guard to the right of the reels like he owns the gaff.
The online slot runs on a 5x4 grid with 25 paylines and a three-modifier pot system that makes the base game feel like it's building toward something, and that’s because it is. High volatility, a 96.52% RTP at its optimum, and a maximum win of 10,000x through the Grand Jackpot. The Egyptian theme is familiar in Pragmatic Play territory, but there's more going on than the visuals initially suggest…

Here are Some Screenshots I Took of the Game
The setting is cast on warm stone and open sky. Sandy desert temple columns frame the reels on either side, and stonework is carved just above, with a clear blue horizon in the background. The reels sit against a deep purple background, and the gold symbols pop cleanly off it. Osiris stands to the right of the grid in full gold pharaoh armour, headdress on, with a long sceptre planted in front of him. I can only guess how long he's been waiting, but behind the sheen of his mask, it’s a hard job to read his facial expressions.
Above the grid, three ornate collection pots are labelled MONEY, JACKPOT, and WILD, with the five jackpot prize values displayed beneath them: Grand, Major, Maxi, Minor, and Mini. Those values sit there throughout the base game and give every spin a quiet sense of direction.
The symbols are rendered in warm gold tones throughout, featuring scarab beetles with blue carapaces, golden falcon statues, decorated vases, and green-and-gold ankh crosses. The Jackpot symbol is a wooden treasure chest with the Eye of Horus, the Money symbol is a gold coin bearing a pharaoh's face, and the Wild a pharaoh portrait in a gold frame with "WILD" lettered beneath it. There’s a bunch of fine details to this slot, but they work hand-in-hand to make the gameplay feel more tangible.

Should You Play the Treasures of Osiris Slot?
If you're comfortable with high volatility and are drawn to Pragmatic Play's pot-collection format, this game is a no-brainer. The three-modifier system gives the ‘free spins’ round a depth that earlier Pragmatic titles rarely managed. The highlighted positions mechanic (where Osiris marks grid spots each spin for special symbols to replicate into) adds a layer of nuance that the studio’s pot-collection titles didn’t quite achieve.
Pragmatic Play is once again nailing a formula they know well. Players who know Gates of Olympus or Book of Dead will clock the familiar visual language. The 96.52% RTP is the best available version. Lower variants of 95.45% and 94.50% exist at some casinos, so check the paytable before you play.
It’s a solid choice if you’re looking for a high volatility slot and enjoy the pot-collection style of the base game, but there are livelier options on the market for players.

My First Moments Playing Treasures of Osiris
Osiris, along with an unmistakably Egyptian orchestral score, has appeared in more online slots than I care to count, and I was half expecting more of the same here. To its credit, the music sets a glistening atmosphere, sweeping across me as more than just background noise. Aside from the soundtrack, though, this slot does plenty more to stand out. Let’s take a look at what sets this slot apart from the rest.
The God of the Grid
The first thing I noticed was Osiris to the right of the reels; his imposing stature, draped in gold armour, completely still, watching. Creepy? Kind of, but what held my attention more were the three pots above the grid.
From the very first spin, special symbols began dropping and collecting into those pots, and this sense of something building to a crescendo gave the slot more purpose than I expected. Even on less fruitful spins with no payline wins, the pots still ticked along. Because of that, I found myself watching the grid more closely than I usually would during a slow opening.
A Familiar Setting, A Less Familiar Mechanic
The visuals are polished and all too familiar. Pragmatic Play knows this theme and the aesthetics reflect that, what surprised me most came later in my session. I’m referring to the free spins round, when the exterior setting dropped away entirely, and I was transported into the interior of Osiris's tomb.
This new slot setting was darker, more enclosed, and felt like I had discovered my own little secret. When the round ended, I came back out to the exterior base game. Then I triggered free spins again, and the tomb pulled me back in! The back-and-forth between the two settings kept me on my toes and felt entirely unique, much like the highlighted positions mechanic, where marked grid spots replicate any special symbols landing in them - this was a winner for me.
Let's Talk About the Bonus Games You'll Find
The whole slot is built around the three-modifier pot system. The paytable has all the details, but here's an in-depth description before you embark on your treasure hunt.
/fit-in/126x126/1763383979/special-symbols.png)
Pot Collection
Three pots sit permanently above the grid: one for Wild symbols, one for Money symbols, and one for Jackpot symbols. Any special symbol that lands on each spin gets collected into its matching pot. At any point, a pot can randomly fire and trigger the free spins round with the corresponding modifier active. Landing all three types during the base game puts you in the best position to enter the bonus.
/fit-in/126x126/1763384119/free-spins.png)
Free Spins
Triggering the bonus pulls you out of the scorching setting of the desert sand and into the interior of Osiris's elusive tomb. When the round ends, you return to the exterior. Trigger free spins again and the tomb swallows you back in. Trust me, this never gets boring!
When entering this cave, you receive 10 free spins. Each spin, Osiris marks a random group of positions on the grid, and what happens to those positions depends on which modifiers are running. If a modifier wasn't present at the start, it can still activate mid-feature when its associated symbol lands, with five extra spins added when that happens. The round can also retrigger randomly at any point, adding another five spins each time. When multiple modifiers fire on the same spin, they resolve in a fixed order of Jackpot transformation first, then ‘Money’, then ‘Wild’, then payline wins.
One thing that’s important to know is that if the total win across the free spins round reaches 10,000x the bet, the round ends immediately and any remaining spins are forfeited.
/fit-in/126x126/1763383725/wild-symbols.png)
Wild Modifier
With this modifier active, any ‘Wild’ landing in a marked position replicates itself across all other marked positions on that spin. Two ‘Wilds' in marked cells applies a 2x multiplier to all line wins, with three then pushing it to 3x. The ‘Wild’ symbol is a pharaoh portrait in a gold frame and substitutes for all regular paying symbols except ‘Money’ and ‘Jackpot’.
Money Modifier
Money symbols are gold coins bearing a pharaoh's face, and each takes a random value from a fixed set: 0.2x, 0.4x, 0.6x, 0.8x, 1x, 2x, 3x, 4x, 5x, 10x, 20x, 50x, or 100x the base bet. With the ‘Money’ modifier running, any ‘Money’ symbol landing in a marked position replicates its value to all other marked positions. If two or three ‘Money’ symbols land in marked cells, their values are added together before that total replicates. A high-value coin dropping into a well-marked grid is where this modifier kicks into gear.
Jackpot Modifier
This modifier fills five jackpot tiers through collection of the treasure chest symbol, each bearing the Eye of Horus. The tiers and their thresholds are:
Mini: 4 collected = 5x your base bet
Minor: 5 collected = 20x your base bet
Maxi: 5 collected = 50x your base bet
Major: 6 collected = 1,000x your base bet
Grand: 6 collected = 10,000x your base bet
A Jackpot symbol landing in a marked position generates additional Jackpot symbols across all other marked positions. Two landing in marked cells triggers the generation twice. The Jackpot modifier is fully disabled during Super Spins, so the Grand jackpot is only reachable through the free spins round.
/fit-in/126x126/1705915646/best-bonuses.png)
Bonus Buy
Three options let you skip the base game and go straight to free spins:
Buy Free Spins (60x bet): 10 free spins with 1, 2, or 3 modifiers randomly active
Super Free Spins 1 (75x bet): 10 free spins with 2 guaranteed modifiers
Super Free Spins 2 (150x bet): 10 free spins with all three modifiers guaranteed
Special Bets
Two side bets sit in the left-hand panel. The Ante Bet doubles your stake and doubles the chance of triggering free spins through natural pot collection. The Super Spin costs 250x your base bet and activates the Wild and Money modifiers with randomly marked positions for that single spin, but the Jackpot modifier is disabled entirely and free spins cannot trigger from a Super Spin.
Some Technical Considerations About Treasures of Osiris
You wouldn't walk into a pharaoh's tomb without knowing what you're dealing with, and the same logic applies here. I read through the full technical side of Treasures of Osiris so you don't have to stand there squinting at the paytable mid-session.
The Return to Player (RTP) is the theoretical percentage of your wagered funds that could be returned over a long period of play. The industry average sits at 96%, and I'd avoid anything below that figure. Treasures of Osiris has a default RTP of 96.52%, which puts it comfortably above the line. The figure shifts slightly depending on which feature you use: the basic Buy Free Spins option edges it up to 96.54%, while Buy Super Free Spins 1 dips to 96.45%. It’s nothing “game-changing”, but it’s worth glancing at the paytable before you start.
Volatility tells you how a slot pays out. High volatility means less frequent wins but larger amounts when they land. Low volatility pays smaller amounts more often. Treasures of Osiris is rated at the maximum for volatility, so expect your gameplay to be a steady climb instead of an instant ascent.
Why Do I Think Treasures of Osiris Stands Out?
Treasures of Osiris is a well-built slot built on familiar ground. Pragmatic Play uses a formula they know well, and experienced players will recognise the DNA. Inside that structure, though, the 10,000x maximum win sits above what most competing Egyptian titles offer, with the likes of Book of Dead capping at 5,000x and the 96.52% RTP is the best available version of the game.
Inside that structure, the modifier combinations are where the idiosyncratic moments lie. A high-value Money coin replicating across a fully marked grid pays out at a decent pace. The three-modifier free spins, with all jackpot tiers running, are about as tense as this style of play gets. Plus, the tomb setting during the bonus round captured me in a world that felt fresh, which is difficult to nail down in a genre as saturated as this.
For players comfortable with high volatility who enjoy the pot-collection style, this slot is worth its weight in gold - and Osiris has plenty to go around! Check the RTP at your casino, pick your entry point, and see what this slot has in store.
