Plot and design of the slot
“Book of Runes” delves into a world of ancient magic and mysteries to uncover. The game’s plot revolves around an ancient book filled with mystical runes, which acts as a portal to hidden riches and age-old secrets. Players are transported into an environment filled with arcane symbolism, where each turn reveals esoteric items such as amulets, glowing runes, and enigmatic figures evoking the traditions of Norse mythology.
The slot's design is a masterpiece of visual aesthetics, combining detailed graphics with fluid animations that enrich the immersive experience. The backgrounds are carefully crafted to depict ancient landscapes and forgotten temples, wrapped in an atmosphere of mystery that captures the player's imagination. The dark colors and golden flashes of the runes create a striking contrast, highlighting the high-quality symbols spinning on the reels.
Rules, symbols and bonuses
“Book of Runes” follows the classic structure of a video slot, with five reels and a variable number of paylines that allows players to adjust their bets according to their preferences. The aim of the game is to line up identical symbols from left to right on one of the active paylines, generating winning combinations that award different prizes depending on the value and rarity of the symbols involved.
Among the symbols in the slot, the classic playing cards (10, J, Q, K, A) with lower values stand out, as well as thematic icons including amulets, mystical runes, and enigmatic characters, which offer higher payouts. However, the most important symbol is the Book of Runes, which plays a double role as a Wild symbol and a Scatter symbol. As a Wild, it can substitute for any other symbol to complete winning combinations. As a Scatter, when it appears three or more times on the reels, it triggers the Free Spins feature.
The free spins bonus round is one of the highlights of “Book of Runes”. At the start of this round, a special symbol is randomly selected to become an expanding symbol. During the free spins, this special symbol can expand to cover the entire reel if a winning combination is possible, significantly increasing the chances of landing big prizes.
Additionally, the slot features a gamble feature that allows players to double their winnings by correctly guessing the color of a hidden card. This option adds an extra level of excitement and risk, allowing players to maximize their prizes if they are feeling lucky.
This game offers an estimated RTP of around 95.5%, which puts it in the industry average for online slots. The RTP of 95.5% indicates that, in the long term, for every 100 units wagered, the game returns approximately 95.5 units to players.
This level of RTP, combined with the volatility of the game, suggests that Book of Runes provides a balanced experience between the frequency of wins and the size of prizes. Players can expect a combination of regular small wins and the possibility of landing larger prizes, especially during the activation of bonus features such as free spins.
