Page updated July 2026
Book Of Oasis is BulBul's desert-themed contribution to the Book slot genre, scheduled for release on 4 May 2026. As the name implies, the setting trades dense pyramid interiors for a sun-drenched oasis, palm trees and shimmering water breaking up the usual sand-and-stone Egyptian backdrop most Book slots default to.
Expect a warmer, more open visual palette than the typical torch-lit temple scene, with the oasis setting offering a slightly fresher take on well-worn desert imagery. On the mechanical side, players can reasonably expect the genre's usual formula to carry through: a Book symbol serving as both Wild and Scatter, Free Spins triggered by landing enough copies, and an expanding symbol mechanic that boosts win potential once the bonus round begins.
BulBul has set the return to player at 96.15% for Book Of Oasis, one of the stronger RTP figures in this batch of releases and comfortably above the 96% line many players use as a quick quality check. That number points to a maths model designed to hand back a healthy proportion of wagered stakes over time.
Rated medium volatility, Book Of Oasis should deliver a fairly even rhythm of wins, avoiding the longest dry spells associated with high-volatility Book slots while still leaving room for a satisfying bonus round when the Books align. It's a sensible choice for players who want steady engagement over big, infrequent swings.
BulBul hasn't confirmed a maximum win multiplier or stake range for Book Of Oasis ahead of its release, so players will want to check the in-game paytable directly once the title launches to see the full detail on potential prizes and betting limits.
Book Of Oasis combines a refreshing desert setting with a genuinely strong 96.15% RTP and an approachable medium volatility profile, making it a promising pick within BulBul's growing Book of catalogue. Players who enjoy the genre's mechanics but fancy a change of scenery from dark temples should keep this one on their radar.
