Book of Olympus Slot Review – Apparat Gaming’s Greek-Inspired Bonus Slot

Book of Olympus is Apparat Gaming’s latest slot release, rooted in classic “Book-style” mechanics. This 5×3 slot comes with 10 paylines, a high volatility profile, and a maximum win of 25,000x your stake. The game uses Greek mythology as its theme, with Zeus standing at the center of the action.

Released in 2025, Book of Olympus follows the familiar setup where the book symbol acts as both wild and scatter. It substitutes for all regular symbols and also activates the free spins round. This dual-role approach simplifies gameplay while keeping the focus on the lucrative bonus round.

Free Spins Feature with Expanding Symbols

Landing three or more Book symbols launches the free spins bonus. Before spins begin, the game randomly selects one special symbol to become expanding. When this symbol appears, it can cover full reels and pays anywhere on the screen, regardless of paylines.

This mechanic maintains the foundation of traditional Book slots. However, Book of Olympus introduces new elements that boost engagement and increase winning potential during the bonus mode.

Bonus Innovations: Respins and Progressive Multipliers

Unlike many “Book-style” games, Book of Olympus includes a Respin mechanic. When the expanding bonus symbol results in a win, the reels respin without using up a spin. This gives players more chances to land winning combos within a single bonus trigger.

The slot also features a progressive multiplier during the bonus round. Each win that includes the special symbol increases this multiplier. As the value climbs, future wins in the same round become significantly more rewarding. This system encourages win streaks and keeps gameplay active.

Design and User Experience

Visually, Book of Olympus embraces a clean, mythological theme. Zeus stands tall, but the graphics never overshadow gameplay. Apparat Gaming has kept the animations minimal, ensuring that players remain focused on the symbols, spins, and evolving bonus rounds.

The user interface is smooth, and the betting range—€0.10 to €10 per spin—caters to casual players and high rollers alike. The game’s design mirrors current trends where game mechanics drive excitement, not excessive visual effects.

Final Thoughts – Is Book of Olympus Worth a Spin?
