Game Theme and Visual Design


Book of Relics transports you to a dusty, forgotten library or perhaps an archaeologist's tent, filled with the promise of discovery. The reels are set against a backdrop of ancient stone and glowing magical energy, with symbols that include classic playing card icons styled as aged artifacts, alongside thematic icons like ornate daggers, golden scarabs, and mysterious potions. The titular Book acts as both the Wild and Scatter symbol, glowing with an otherworldly light. The audio design complements the theme perfectly, with a suspenseful, adventurous soundtrack and satisfying sound effects for wins and special features, creating an immersive atmosphere that pulls you into the hunt for relics.

How to Play Book of Relics


Getting started with the Book of Relics slot is straightforward. The game uses a standard 5x3 reel grid with a fixed number of paylines, meaning all lines are active on every spin. Your first step is to set your total bet using the intuitive controls at the bottom of the screen. The minimum bet is $0.10, while the maximum reaches $200, offering substantial flexibility. Once your bet is set, you can either click the spin button to start the reels manually or use the autoplay function to set a predetermined number of consecutive spins. The goal is to land matching symbols on adjacent reels, starting from the leftmost reel, to form a winning combination. The highest-paying standard symbol is the golden mask, so keep an eye out for that as you spin.

Special Features and Bonus Rounds


The true excitement in Book of Relics lies in its special features, which are central to unlocking the game's bigger win potential.


The Book Symbol (Wild & Scatter)


The ancient Book is the most important symbol on the reels. It serves a dual function: as a Wild, it can substitute for any regular symbol to help complete winning combinations. More importantly, it acts as the Scatter. Landing three or more Book symbols anywhere on the reels triggers the main Free Spins bonus round.


Free Spins with Expanding Special Symbol


When you trigger the Free Spins feature by landing 3, 4, or 5 Book Scatters, you are first awarded 10 free spins. Before the round begins, one regular symbol is randomly chosen to become a special expanding symbol. During the free spins, if enough of this chosen symbol land on the reels to form a potential win (even just 2), they will expand to cover their entire reel. This expansion can lead to multiple winning combinations across the paylines simultaneously, significantly boosting your payout. This mechanic is reminiscent of the popular features found in many slots like Starburst, where expanding symbols create cascades of wins.


Re-triggering Free Spins


The adventure doesn't have to end after your initial 10 spins. If you land three or more Book Scatter symbols again during the free spins round, you will re-trigger an additional 10 free spins. This can happen repeatedly, offering the chance for extended gameplay and more opportunities to land those valuable expanding symbol wins.

Volatility, Betting Range, and RTP


Book of Relics is classified as a medium volatility slot. This means the gameplay offers a middle-ground experience between low-volatility slots (frequent, smaller wins) and high-volatility slots (infrequent, larger wins). It's an excellent profile for players who enjoy a bit of suspense without extremely long dry spells between bonuses. The betting range is notably wide, accommodating a minimum total bet of $0.10 and a maximum of $200. This makes the game suitable for casual players and those with larger bankrolls alike. Book of Relics carries an official RTP of 96%, in line with the industry average. As always, understanding a game's risk profile is key; you can learn more about this in our detailed slot volatility guide.
