Treasures of Osiris – What Is This Slot?
Pragmatic Play has rolled out a new high-volatility slot called Treasures of Osiris, launched on 19 February 2026 on a 5×4 grid with 25 paylines. Set in ancient Egypt during the era of legendary pharaoh Osiris, the slot features a unique Pot Collection mechanic — three pots are fixed at the top of the grid and each is linked to one of three special symbol types. The symbols collected in each pot trigger Free Spins and build jackpot meters on every single spin.
With a slightly larger playing grid (5×4 as opposed to the traditional 5×3), the board provides more space for scatter symbols to drop. Paylines run left to right, paying for matching 3, 4 or 5 symbols. The max win is 10,000× your bet — achievable during Free Spins with jackpot meters filled and all 3 modifiers active. The Grand Jackpot alone is worth 10,000× — it only needs to pay once for the ceiling to be reached.
How to Play Treasures of Osiris
- Set your bet between €0.25 and €250 per spin (up to €2,500 using Special Bets).
- Spin the 5×4 grid — 3, 4 or 5 identical symbols from the leftmost reel pay a cash prize.
- Money Symbols, Jackpot Chest Symbols and Wild Symbols always appear on the reels. Money Symbols award instant cash (0.20×–100×). Jackpot Chests display a jackpot name and fill the corresponding meter. Wilds replace all regular symbols and pay like the Ankh.
- Any special symbol collected in the pot above the reels is credited to the balance. Money and Jackpot Chests also add their values to a Coin Meter which pays out instantly in addition to any line wins.
- Free Spins are triggered randomly when scatter symbols drop. The types of scatter in play at the time determine which of the 3 modifiers are initially active.
- With Ante Bet (2× stake) you double the chances of triggering Free Spins. With Super Spin (10× stake) you ensure marked reels feature active Wild and Money modifiers for that spin.
- Skip the wait with the Buy Feature: 60× (1–3 random modifiers), 75× (2 guaranteed modifiers), or 150× (all 3 modifiers guaranteed).
Bonus Features
Pot Collection
Three pots above the reels collect their assigned special symbols with every spin. Money Symbol values (0.20×–100×) fill a progressive meter and pay out as an instant win, in addition to any line wins — a cash drip not often seen in base games.
Fixed Jackpots
Jackpot Chest Symbols show the name of the jackpot and fill the corresponding meter. Once a meter is full, the jackpot pays out and collection continues until the feature rounds out. Mini 5×, Minor 20×, Maxi 50×, Major 1,000×, Grand 10,000× the bet.
Wild Symbol
The Wild substitutes for all other symbols and pays like the Ankh: 0.40×–10× for 3–5 in a row. It is also collected by the Wild Pot and triggers bonus features. During Free Spins, Wilds on marked positions fill the other marked positions with Wilds — 2 or 3 Wilds in a row apply a ×2 or ×3 multiplier for winning combinations.
Special Bets
In Ante Bet, your stake is doubled and the chances to trigger Free Spins are also doubled. Super Spin costs 10× the stake and guarantees symbols to fall into marked positions with active Wild and Money modifiers on that one spin — almost like a one-spin power mode.
Free Spins & Buy Feature
Free Spins are triggered by scatter symbols, dropping on average once in ~100.45 spins. The types of scatter that fall decide which of the three modifiers are activated — and the player always receives 10 free spins. Any time a new modifier is levelled up during the bonus, 5 extra spins are awarded and the newly activated scatter type becomes active too, so mid-bonus escalation is always possible.
During Free Spins, marked positions appear randomly on the reels. When a special symbol lands on a marked spot, a powerful chain effect fires:
- Jackpot Chest on marked position — fills all other marked positions with Jackpot Chests. Two chests on marked positions cause the effect to occur twice.
- Money Symbol on marked position — all marked positions fill with Money Symbols. Two or three landing together pay out the sum of their values.
- Wild on marked position — all marked positions fill with Wilds and all possible line wins are evaluated. Two Wilds = ×2 multiplier; three Wilds = ×3.
These effects pay in sequence: Jackpot → Money → Wild. Multiple jackpots can pay in one bonus round — the meter fills with each jackpot until it is paid, then collection resumes for subsequent spins.
| Buy Feature Option | Cost | Modifiers |
|---|---|---|
| Free Spins | 60× bet | 1, 2, or 3 active (random) |
| Super Free Spins 1 | 75× bet | Guaranteed 2 modifiers |
| Super Free Spins 2 | 150× bet | Guaranteed all 3 modifiers |
RTP & Variance Explained
Treasures of Osiris slot RTP varies, though the best version delivers a payout rate of 96.52% while featuring high volatility. Two lower variants exist at 95.45% and 94.50% — it's worth verifying which is active at your casino before committing with real money. The hit frequency is 27.85% (~1 in 3.59 spins), acting as a mitigating effect for the high volatility — resulting in a larger number of smaller winning prizes between the bigger bonus-driven payouts.
The max win of 10,000× has a payout frequency of around 1 in 887,784 spins — quite a bit more frequent than many other modern slots. High volatility gives a relatively dry base game, but the collectible Money Symbols provide a fairly steady trickle of wins to keep things ticking over between features.
