What to expect when playing the Treasures of Osiris slot

Developer Pragmatic Play once again borrows from Egyptian mythology for the theme of its brand-new slot, Treasures of Osiris, a familiar release centered on multi-modifier free spins and collectible pots.

If there are two things Pragmatic is famous for, it’s fruits and mythology themes in online slots. After running out of Greek mythology-themed content, the provider is now turning to Egyptian gods for its next release.

Treasures of Osiris is easy on the eyes, with high-contrast symbols and a staff-wielding Egyptian figurine on the side, drenched in gold. The symbols aren’t as tight a fit, but they somehow still play into the Egyptian theme. Here’s what to expect when playing this game, which delivers a reliable Pragmatic Play slot experience.

Treasures of Osiris is a standard Pragmatic slot done well

Structurally, Treasures of Osiris is quite similar to recent some other Pragmatic Play releases. It runs on a 5×4 grid with 25 fixed paylines, sticking to Pragmatic’s familiar reel structure but stretching the board slightly taller than usual. Wins pay left to right, and the symbol set is exactly what you’d expect from a Pragmatic release.

The top-paying icons are Egyptian-themed symbols such as ankhs, birds, scarabs, and vases, while the low-paying set consists of standard royals from 10 through Ace. Five-of-a-kind combinations on premium symbols usually land in the mid single-digit multipliers, while wild lines pay higher and can reach around 10x the stake on their own.

The slot ships with multiple RTP versions, with the best topping out at 96.52%, while lower configurations dip into the mid-95% or even the 94% range depending on the casino. The game’s volatility is on the higher side, so don’t be surprised if wins make you sweat.

With a max bet size of $250, Treasure of Osiris is truly a slot for all types of players. The game’s max win is capped at 10,000x the bet, which puts it in line with many modern Pragmatic releases without pushing into their high-ceiling territory.

Treasures of Osiris gameplay and features explained

Treasures of Osiris plays like a familiar Pragmatic title on the surface, but the gameplay really hinges on how the modifier system interacts with highlighted positions. The base game is pretty simple, and its more interesting variations and the potential for big wins really come from collectible pots that fill up as you play.

Money, Jackpot, and Wild symbols are gathered passively, and while base game payouts are modest, Money symbols can still drop direct values between 0.2x and 100x the bet, which helps to improve otherwise slow spins.

Free spins in this slot are crucial, as that’s where the game flexes its volatile nature.

The game initially offers 10 such spins when they’re had, but the value of the bonus really depends entirely on how many modifiers are active at a time, regardless of the number of spins available. One modifier won’t have much to offer, two is decent, but if players are lucky enough to land three modifiers, they may actually be on their way to challenge the slot’s max win potential.

The main mechanic on the Treasures of Osiris slot is the jackpot ladder, which works off collected chest symbols rather than through instant reveals:

Mini jackpot: 5x bet (4 symbols)
Minor jackpot: 20x bet (5 symbols)
Maxi jackpot: 50x bet (5 symbols)
Major jackpot: 1,000x bet (6 symbols)
Grand jackpot: 10,000x bet (6 symbols)

During free spins, highlighted tiles randomly appear, and if a matching symbol lands there, the modifier spreads across all marked positions. That’s where the bonus opportunity can really explode, especially if Wilds or Money symbols multiply across the grid in a single spin. It’s important to note that new modifiers can activate mid-bonus and award extra spins, which gives the feature a second wind if it starts cold.

Overall, Treasures of Osiris doesn’t reinvent the wheel, but the way it stacks modifiers together through highlighted spots keeps the gameplay tense for players who enjoy Pragmatic’s higher-volatility releases, and ancient Egyptian theme is definitely well-represented.

Treasures of Osiris is available to play on Roobet, which our Roobet review found to be one of the best platforms available online for playing new slot games. Players can try out the slot through its free play mode to get a grip on its mechanics and winning potential before then diving into the excitement with real-money bets.
