[Slot review] Ancient Treasure: Poseidon — Microgaming
Six reels, 117,649 ways and an 18,000x cap — the fourth-highest cap among Microgaming slots that publish one in this catalogue, and the highest within the 117,649-ways format. Published RTP 96.10%, High volatility, bets 0.10 to 20.00.
Overview
Ancient Treasure: Poseidon is a six-reel, 117,649-ways slot Microgaming released on 26 November 2025. The studio's feature list is empty; what is published is RTP 96.10%, High volatility, an 18,000x cap and bets of 0.10 to 20.00.
Not many Microgaming slots in this catalogue publish a max win. Of those that do, only three sit above 18,000x: K-POP Hunter Zeus (50,000x), Merlin's Secret Maxways (40,000x) and Wrath of Seth - Split (21,000x). This review reads it alongside other Microgaming titles in the same 117,649-ways format.
Layout and rules
117,649 is 7 to the 6th power — the route count when six reels each have up to seven symbol positions, so the format is usually quoted at its maximum on builds where reel heights vary. As a ways game, any run of matching symbols on adjacent reels from the left pays regardless of row. Whether this title's reel heights are fixed or variable isn't recorded in the catalogue.
An empty feature list doesn't mean there are no features; it means the studio didn't fill in the field. Details like free spins or wild rules have to be checked in the in-game help.

Reading the numbers
Among Microgaming's 117,649-ways titles, only two publish a cap: this one and Almighty Dionysus Empire (96.22%, High, 5,000x). Crazy Rich Tigers (96.36%, Very high) publishes no cap, and Break Away Max and Curse of Medusa don't publish an RTP either.
The comparison with Dionysus Empire is revealing. The two share a format and a volatility grade (High), yet their caps are 5,000x and 18,000x — more than three times apart. Within one grade, caps are set per game, which also means the grade alone can't tell you the cap.
At 96.10%, the RTP is 0.12 points below Dionysus Empire. A higher cap doesn't push RTP up or down — RTP is the long-run average of all payouts, and the cap is a single point at the far end of that distribution.
Presentation
On the cover Poseidon rises from a green sea with his trident already raised, his hair moving in some current that isn't water. Dressing a sea god in green and gold is an unusual choice, and it gives the piece the excavated feel the 'Ancient Treasure' title promises.
A demo is available, so you can see what the 117,649-ways screen actually looks like and what sits behind the empty feature list. The larger the ways count, the more readability depends on how the screen marks a spin's winning routes.
Strengths
- Highest published cap in the 117,649-ways format (18,000x)
- RTP, volatility, cap and bet range are all published
- The green-and-gold palette conveys the theme memorably
Weak points
- The studio's feature list is empty
- Whether reel heights are fixed or variable isn't published
- A high cap says nothing about how often it's reached
Verdict
Set against Almighty Dionysus Empire — same format, same grade — Ancient Treasure: Poseidon shows most clearly that caps are set game by game. 18,000x is an end point, not an expectation.
