Book of Merlin by 1x2 Gaming takes the classic “Book of” formula and immerses it in Arthurian magic. Instead of dusty pyramids, your reels are backed by mystic forests, wizard towers and spellbooks that promise hidden riches. This video slot plays on a 5×3 grid with 10 fixed paylines and centres around a magical book that acts as both Wild and Scatter. Trigger the free spins bonus and a chosen expanding symbol starts working its way across reels to unlock bigger combinations and real win potential — up to 5,000× your stake if luck is on your side.

Immediately you get a sense that this isn’t just another walk through the tombs. Here there’s magic in the air, runes glow softly on the reels, and symbols like potions, scrolls and Merlin himself fill the screen. It’s a familiar set-up if you’ve played other “Book of” style slots before, but the mystical theme makes it feel a bit more enchanting and less like you’ve seen it all before.
Book of Merlin plays on five reels and three rows with 10 fixed paylines where wins are formed by matching symbols on adjacent reels from left to right. The Book symbol is your key to the bonus. It works as both Wild and Scatter, helping you complete wins in the base game and triggering the free spins feature when three or more land anywhere on the reels.
When the free spins bonus begins, you’re awarded a set number of spins and one regular symbol is randomly selected to become the special expanding symbol for the duration of the feature. Whenever that chosen symbol lands in a winning combination during the free spins, it expands to cover the reel position, giving you a much better chance of forming bigger combinations. That’s where the biggest wins come from — a reel full of expanded symbols can trigger serious payouts, especially with enough spins and retriggers to keep the action rolling.
Landing additional Book symbols during the feature can retrigger more free spins, stretching the bonus run and giving you even more chances for those expanding symbols to land. It’s a familiar mechanic, but when it clicks it gives you that satisfying feeling of watching the screen light up with symbols lining up in ways you didn’t expect.
1x2 Gaming’s visuals here lean into the mystical theme without overwhelming the player. The background features enchanted woodlands and rune-carved stones, while the symbols themselves are detailed enough to feel like part of the story without cluttering the screen. The audio adds some subtle magic too, with twinkling tones and ambient atmosphere that make each spin feel like a step deeper into the forest.
Gameplay is smooth and intuitive. Base spins come at a steady pace, and while the biggest thrills wait for the bonus feature, the clear layout makes it easy to see when things are building toward something more exciting. When the chosen expanding symbol starts filling reels, that’s when the game really wakes up and keeps you watching rather than just tapping spin and walking away.
Book of Merlin is a solid twist on the classic book slot genre, pairing familiar mechanics with a Norse-myth infused wizard theme that feels fresh without reinventing the wheel. If you enjoy free spins with expanding symbols and the potential for big combinations, this one delivers without a fuss. The magical setting adds atmosphere that keeps you engaged, and the retriggers give those bonus sessions real momentum. Take a spin at LuckyMate — you might just unlock Merlin’s secrets one spin at a time.
