Book of Oasis

Book of Oasis is Gamomat's contribution to the ever-expanding library of desert-set book slots, promising the studio's usual clean production values wrapped around a mirage-chasing theme. Gamomat has built a loyal following in European markets through titles like the Book of Romeo and Julia and Golden Nights Bonus series, and Book of Oasis looks to extend that lineage with an oasis-and-dunes take on the classic expanding-symbol format.

Expect the visual language to lean into shimmering water, palm trees and sun-baked sand rather than tombs and pyramids — a subtly different desert setting from the usual Egyptian archaeology angle, even if the underlying gameplay skeleton follows the same well-trodden path. Gamomat's house style tends to favour crisp symbol design and understated animation over flashy cinematics, which should suit players who prefer substance to spectacle.

On the numbers, Book of Oasis carries a 96.15% RTP, a genuinely strong figure that puts it ahead of a good chunk of the book-slot field, including several bigger-name entries in the genre. That payback rate alone makes it worth a look for RTP-conscious players who track theoretical return before choosing where to spin. Medium volatility completes the picture, suggesting a game engineered for a balanced rhythm — enough smaller wins to keep sessions ticking along, with the bonus round providing the bulk of the excitement rather than wild base-game swings.

As with virtually every book slot, the free spins feature built around an expanding special symbol will be doing the heavy lifting here. Landing enough scatters should trigger the round, at which point one symbol is nominated to fill entire reels for the duration, stacking up wins in the way that made the genre's forerunners so popular in the first place. Gamomat hasn't published a confirmed max win, reel configuration or stake range for Book of Oasis at the time of writing, so treat those finer details as still to be confirmed, but the RTP and volatility figures already paint a reasonably clear picture of the intended player experience.

Given Gamomat's track record with the format — reliable, well-balanced math models rather than headline-grabbing but unsustainable numbers — Book of Oasis looks like a safe, above-average pick for anyone who enjoys the genre's rhythm without wanting to chase the riskiest volatility extremes. It's a game built for steady sessions rather than boom-or-bust swings.
