The B2B games developer Onlyplay has released its latest video slot, titled “Mummy Coins”, and the studio is leaning into the ever-popular ancient Egyptian theme with clear intent. The title sticks to a compact 3 × 3 reel layout but layers on cinematic design flourishes, five progressive jackpots and both a Bonus Game and Free Spins round. The game carries an RTP (return-to-player) of 95.05 % and a hit rate of 7.25 %.
Here’s a deeper look at what Mummy Coins offers and what its release may signal for the wider online casino slot-market.
Mummy Coins sticks with a compact 3 × 3 reel structure, a configuration that has seen renewed interest as operators seek simpler game formats that still deliver excitement. The design choice works in Onlyplay’s favour: fewer reels mean clearer symbol patterns, more immediate results, and typically faster play cycles.
That said, the game isn’t content with simplicity alone. When three Scatter symbols land, players trigger a Bonus Game set within a “tomb of gold”. During that bonus mode, the reels incorporate Special, Wild and Scatter symbols with heightened potential. The main game also includes a Free Spins mode, triggered by three Wild symbols.
Most notably, Mummy Coins features five progressive jackpots (Mini, Minor, Major, Mega and Grand) triggered by Special Symbols. The bet size influences the scale of the reward, adding a risk-reward dimension often seen in modern slots.
The stated RTP of 95.05 % sits on the lower side of what is typically seen in online slot games today (many fall in the 96–97 % range). The hit rate of 7.25 % suggests relatively infrequent “wins” in the sense of symbol hits, although variability in win size and jackpot triggers will factor heavily into player experience.
From a strategy perspective, this suggests the slot is tuned more for medium volatility: moderate frequency of action but bigger payouts remain accessible via the jackpot feature. That aligns with Onlyplay’s stated ambition to “capture everything players love about slots—risk, excitement and reward.”
The ancient Egypt theme remains a perennial favourite in the slot world. Pyramids, sarcophagi, hidden treasures, mummies—they deliver visual recognisability and immediate thematic context for players. Onlyplay seems to lean further into the immersive aesthetic with “the desert wind, the gleam of gold dust” and so on—linguistic flourishes meant to evoke atmosphere.
For operators, a visually rich but compact format like this slot offers flexibility: mobile-friendly, quick to load, and accessible to casual players while still offering jackpot allure for more experienced users. In a market that’s crowded with 5-reel, multi-payline games stuffed with bonus features, a 3×3 slot with strong visuals and one jackpot mechanic can help stand out.
Refinement of compact formats – Mummy Coins demonstrates how developers are refining smaller-format slots (3×3 or 4×3) rather than simply scaling up reels/lines indefinitely.
Jackpot mechanics embedded, not add-ons – The five progressive jackpots are integrated into the core gameplay, not just “optional” extras; that plays into players’ reward-chasing instincts.
Balancing accessibility and depth – By using a familiar layout but layering in Free Spins + Bonus Game + jackpots, Onlyplay appeals to both novices and more seasoned slot-players.
Continued reliance on evergreen themes – While modern slots experiment with narrative and brand licenses, themes like “ancient Egypt” remain a safe bet for recognisability and excitement.
For operators and players alike, Mummy Coins offers a neat package: strong theming, straightforward gameplay, jackpot potential and an RTP/hit-rate profile that emphasises entertainment over ultra-high return. From a market-perspective, it underlines how slot-developers continue to iterate within the compact-format space rather than simply increasing complexity.
Players should of course review pay tables, jackpot rules and bet-levels before playing. Operators may find value in positioning this game as a “session starter”-type title: quick spins, visible jackpots, and high visual impact.
