Page updated July 2026
Book of Elements slot also appears under developer BulBul, carrying the same core numbers as other releases sharing its name but arriving through a different studio's distribution. It's a reminder that the book-slot format has become something of a shared blueprint across the industry, with individual studios each putting out their own take on the same reliable skeleton.
This version leans on elemental imagery — think fire, water, earth, and air motifs — as its dressing over the classic book-slot structure. Expect the standard division of labour on the paytable: card-rank symbols handling the low end, thematic elemental icons carrying the mid-to-high value combinations, and a dedicated book-style symbol on hand to unlock the free spins round, where expanding symbols do the heavy lifting.
Book of Elements slot under the BulBul banner returns 96.13% to players, matching what's typically seen across this particular title's various releases. That's a fair, above-average figure for the genre, giving players a reasonable long-run return without needing to chase down a specifically boosted configuration.
Rated medium volatility, this build should play out with a steadier rhythm than the book genre's most aggressive high-variance entries. Expect a more regular cadence of smaller and mid-size wins in the base game, with the expanding-symbol free spins round still supplying the standout moments without demanding the same nerve as a 5/5-rated stablemate.
There's no published max win figure attached to this release, so it's best not to assume it lines up with other book slots in the wider market. As always in this genre, any serious multiplier is going to come from a well-timed free spins trigger and a generous expanding symbol rather than base-game combinations alone.
Book of Elements slot's BulBul release is functionally a sibling to other elemental-themed book slots out there, sharing the fair 96.13% RTP and approachable medium volatility that make the format easy to recommend to newer players. If you've already sampled a differently-branded version of this game and liked it, this is a low-risk way to see whether the BulBul build feels any different in practice — try the free demo at johnessyslots to compare for yourself.
