A close look at Book of Olympus, from theme and features to every spin.
Book of Olympus takes the well worn Book slot formula into the realm of Greek mythology, courtesy of German studio Apparat Gaming. The 5x3 grid runs on 10 fixed paylines, with the Book symbol acting as both wild and scatter, substituting for all symbols along paylines and opening the door to Free Games when three or more appear. What sets this release apart is a respin mechanism layered onto the classic Book feature. During Free Games, wins involving a golden Bonus symbol prolong the sequence with a respin and raise an escalating multiplier, pushing payouts towards the game's substantial 25,000x maximum exposure. It is a twist that rewards sustained bonus rounds rather than relying purely on the expanding symbol alone. The theme leans into thunderbolts and marble temples befitting Zeus's domain, with a high volatility rating of five out of five reflecting the game's boom or bust nature. A Buy Feature option is also available for players who want to skip straight to the Free Games, though this comes at a steep price relative to the stake.
Slot Rating
* Exact score 3.2875, rounded to 3.3 for display.
Book of Olympus channels genuine godly ambition into a well trodden genre, stacking a respin and multiplier twist on top of the usual Book formula. It thunders when the Free Games hit, but patience is required between strikes.
