Great Book of Magic Slot Review

The one feature on record

The bonus is a Free Spins round in which an Expanding Bonus symbol comes into play. Wazdan presents this symbol as the heart of the game but does not explain, in the material we hold, how the round is triggered, how many spins it gives, or how the expansion works. Based on the name, the symbol grows to cover more of the reels when it appears, but the exact rule should be checked in the game's own paytable.

No other features, such as multipliers, buy options or ante settings, are described in our source.

Return and cost

The single listed RTP is 96.47%, which leaves a house edge of 3.53%. On average that is about $35.30 lost per $1,000 wagered. One hundred spins cost an average of $0.71 at $0.20, $3.53 at $1 and $17.65 at $5.

Volatility and the 5,150x figure

Wazdan rates the volatility as High, so long gaps between meaningful wins are normal, and much of the return is likely to come from the free spins. Our catalogue has no maximum win for this title. The studio's page states that the biggest prize is 5,150x the player's bet; we pass that on as Wazdan's figure, not as catalogue data.

A ceiling that sits so far above the average cost of a session is a reminder that the long-run return is built from many small outcomes and a handful of rare large ones. The 5,150x prize should be read as a limit, not a likely result.

The Deluxe version and other 2018 Wazdan titles

Great Book of Magic Deluxe, from the same year, shares the 96.47% RTP and the High rating. Magic of the Ring Deluxe, another 2018 release, also lists 96.47% with High volatility, while Highway to Hell Deluxe reaches 96.56% and Football Mania Deluxe 96.59%. Fruit Mania Deluxe, also from 2018, lists 96.59% too, and Hungry Shark from 2017 shares the 96.47% figure. No official demo is listed for this game in our data, which makes the paytable inside the game the main source for the detailed rules.
