Books and Pearls ROAR

Books and Pearls ROAR is a BulBul-published edition of Gamomat's ocean-themed book slot, due 4 May 2026 with a 96.1% RTP and medium volatility — figures that align with the ROAR edition listed under Gamomat elsewhere in our catalogue. As with other suffixed variants across this family, "ROAR" identifies a specific licensed build of the base Books and Pearls game, distributed here through BulBul's own casino platform network.

The theme takes the familiar book-slot respin format underwater: pearls, oysters and sunken treasure surround a central tome symbol that drives the game's main bonus. Landing enough copies of the book triggers a respin round in which matching icons lock in place while the rest of the grid spins again — a structure that lets a single feature trigger snowball into a larger combined payout across several respins rather than resolving on one static combination.

At 96.1% RTP, this ROAR edition sits comfortably above the standard 96% benchmark carried by many slots in this bracket, offering a modest edge in long-run expected return for players who track these differences across editions. Medium volatility keeps the pacing balanced — expect the respin feature to fire with reasonable regularity, giving sessions a steady rhythm without the extended cold stretches typical of higher-variance games.

We don't have confirmed reel and payline data or a maximum win figure for this specific BulBul build, so this review is grounded in the verified numbers only — RTP, volatility, theme and release date — rather than borrowing details from a related edition.

BulBul's presence as publisher here is worth noting once more: the studio distributes proven Gamomat designs like Books and Pearls to a broader spread of casino platforms under its own listing, which is why you'll find the ROAR edition catalogued under two provider names with matching core mechanics but distinct listings.

For players who enjoy the ocean-themed spin on the classic book-slot respin format, this ROAR edition delivers exactly what the Books and Pearls name promises, with a small RTP edge over some sibling editions.
