Play Book of Merlin Slot

Merlin has been the subject of many myths, but this time, he’s trading in Camelot for the reels. Book of Merlin by 1x2 Gaming taps into the legendary wizard’s spellbook, conjuring up a slot with all the familiar hallmarks of a Book of... game — expanding symbols, free spins, and an air of mystery. The theme leans into fantasy rather than history, going deep into Merlin's potion-filled study, where glowing tomes and arcane artefacts clutter the background. 

Mechanically, Book of Merlin follows a well-trodden path. The game plays out on a 5x3 grid with 10 paylines, a format that has become standard for this type of slot. The spellbook serves as both the wild and scatter, triggering the Free Spins round when three or more appear. The minimum bet is 0.10, making it accessible, while the potential for big wins lies in the classic expanding symbol feature that defines this slot type. 

1x2 Gaming is no stranger to bringing mythical themes to life, with past releases like Battle Maidens and Pirate Kingdom Megaways offering different takes on fantasy storytelling. Book of Merlin joins their lineup with a straightforward yet polished execution of the Book of... concept.

The symbols in Book of Merlin split between classic playing cards and more thematic elements tied to the world of Merlin. The low-paying symbols include 10, J, Q, K, and A. The higher-value symbols bring the magic to life, featuring a pendant, a wand, and Merlin himself. A complete paytable is given below: 

Apart from the symbols above, there is also the Book symbol, which pulls double duty, acting as both the wild and the scatter in this case. As a wild, it substitutes for all other symbols in the game and helps form potentially winning combinations. As a scatter, the Book is responsible for activating the Free Spins bonus. 

Free Spins Feature 

The spellbook scatter does double duty, acting as both the wild and the scatter. Landing three, four, or five of these mystical tomes anywhere on the reels will trigger 10 free spins. Notably, the book also awards payouts of 2x, 20x, or 200x the stake when triggering the round. 

Expanding Symbols 

Before the Free Spins round begins, a random symbol is selected to become the expanding symbol for the duration of the feature. Whenever enough of these symbols appear on the reels, they expand to cover the entire reel, paying out regardless of paylines. This feature is where the game’s biggest potential wins come into play, especially if Merlin himself is chosen as the expanding symbol. 

Wild Substitutions 

Since the spellbook also acts as a wild, it substitutes for all regular symbols, helping to create winning combinations. However, it does not replace the special expanding symbol during the Free Spins. 

If Book of Merlin piques your interest, other Book of... slots might be worth a look. Rise of Merlin by Play'n GO has a similar magical theme with free spins and expanding symbols, while Book of Oz from Microgaming brings another twist to the format. For a classic Book of... experience, Book of Dead remains one of the most well-known examples of the genre. All are available at Heart Bingo.
