Book of Relics is a release from Light & Wonder, built around a book of theme. It runs on 20 paylines across 5 reels with a very high volatility profile, and a published RTP of 95.96%.
The mechanics are what make Book of Relics interesting. A progressive jackpot adds a wildcard payout that can land at any time. Look out for scatter symbols that unlock free spins and extra bonus rounds. With very high variance, this one is aimed at players who can ride out the swings for the top wins. All told, it's a solid entry in the Light & Wonder catalogue.
At 95.96%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.
Very high volatility delivers the most extreme payout profile — long dry spells punctuated by potentially massive wins. Only recommended for experienced players with substantial bankrolls and high risk tolerance.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Book of Relics features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
Book of Relics features a progressive jackpot that grows with every spin placed by players across the network. The jackpot can be triggered randomly or through a special bonus feature, offering the chance to win a life-changing sum. The jackpot continues to grow until one lucky player hits the winning combination.
3.1 / 5 — Good
