Our take
High-volatility Mesopotamian book slot from Hölle Games with 5000× max win and buy-bonus feature.
Book of Ishtar is Hölle Games' foray into the ancient-mythology book-slot space, blending Mesopotamian (Ishtar) and Egyptian iconography across 5 reels, 3 rows, and 10 paylines. At 95.03% RTP, it sits at the lower competitive threshold. The game's differentiator is the buy feature—players can purchase direct access to the free-spins round without waiting for scatter triggers, trading additional bet cost for immediate bonus play.
High variance means payouts cluster infrequently but substantially. The 5000× maximum is achievable via the base game or free spins, where symbol expansion and re-triggering mechanics amplify payouts. Scatter symbols trigger the bonus round at no additional cost; risk/gamble features post-win let players compound successful spins through card-colour guessing.
The blended mythology theme—Ishtar, pyramids, and ancient artefacts—gives visual distinction from standard Egyptian offerings. Hölle Games' execution is competent, though feature innovation is limited. High volatility demands bankroll discipline.
