Treasures of Osiris hits the sweet spot between high RTP and genuine win potential. The triple modifier system is where Pragmatic earns their stripes — get all three active and this slot becomes a different game entirely.
Treasures of Osiris is Pragmatic Play's latest deep-dive into ancient Egypt — a theme they know well, but have given new depth here through a layered modifier system rather than a simple free spins round. Running on a 5×4 grid with 25 fixed paylines, the game pairs one of Pragmatic's highest RTPs (96.52%) with High volatility, creating a setup that rewards patient play.
The standout feature is the free spins round that can trigger with up to three simultaneously active modifiers, each dramatically changing how wins are built. This isn't a slot where you hope for a lucky scatter — it's one where the architecture of the bonus itself determines the scale of what's possible. For Pragmatic fans who've played the Big Bass series or Sweet Bonanza, this represents a more sophisticated direction.
The free spins round can activate with 1, 2, or 3 modifiers simultaneously. More active modifiers means greater complexity and significantly higher win potential.
Special Money symbols land within dedicated frames on the reels during the bonus. When filled, they award their cash value directly — expanding as the feature progresses.
Progressive jackpot meters sit above the reels during the bonus. Enough qualifying symbols fill them to award Mini, Minor, or Major jackpot prizes on top of base wins.
When active as a modifier, all line wins in the free spins round receive a 3x multiplier — stacking on top of Money symbol values for compounding payout potential.
Increase your bet by 25% to raise the frequency of scatter symbols and improve the odds of triggering the free spins with more modifiers active from the start.
The free spins round is the core of Treasures of Osiris and where the 96.52% RTP is most fully realized. Triggered by landing scatter symbols (Ante Bet increases scatter frequency), the bonus activates with 1, 2, or 3 modifiers depending on how many scatters triggered it and which were randomly selected.
With all three modifiers active — Money symbols expanding within their frames, the Jackpot meter filling alongside, and a 3x multiplier applied to every line win — a single free spins session can produce wins that reach the 10,000x ceiling. The Jackpot meter in particular adds a progressive-style layer that keeps the bonus active and building even when individual spins are modest.
For players who prefer to buy-in: Pragmatic typically offers a Bonus Buy option at a competitive price for Treasures of Osiris, placing it within reach for both mid-stakes and high-stakes players wanting direct access to the feature.
