Our Review of Book of Merlin

Book of Merlin Slot Overview: Fire or Mid?

Book of Merlin from 1x2 Gaming is a classic book style slot with a full wizard fantasy makeover. You get a 5x3 grid, 10 fixed paylines, high volatility and that signature expanding symbol free spins round that can go absolutely crazy.

If you like high risk high reward slots and you are hunting that Book of Merlin max win potential, this one is built for you. Newer players can still vibe with it, but the math is spicy and the Book of Merlin RTP at 95.8 percent is a bit lower than the usual book clones.

How the Gameplay Hits

Here is how to play Book of Merlin without getting cooked. The slot runs on 5 reels and 3 rows with 10 fixed paylines paying left to right. Wins land when you match 3 or more symbols on a line, except Merlin himself who can pay from just 2.

Bets start at 0.10 and go up to 50 per spin, so you can keep it casual or crank the stakes. The volatility is high so expect a lot of dead or tiny spins, with the balance doing that roller coaster thing until the book symbols finally wake up.

The base game is pretty simple. No random modifiers, no crazy side mechanics. You are mostly spinning to line up premium symbols like the wand, amulet, potion and of course Merlin who can pay 500x for a full line. The feel is old school book slot with a fantasy twist. When the game is cold it feels super mid but when it hits, it hits different.

The Hype Moments: How to Trigger Bonus Features

  • Wilds: The Book of Spells is your wild symbol. It subs for every regular symbol to help complete winning lines on the 10 fixed paylines. In the base game this is clutch for keeping your balance alive while you wait for the real sauce. Wild hits with Merlin or other premiums can spike some low key decent line wins.
  • Scatter Symbols: That same Book of Spells also acts as the scatter. Land 3 or more anywhere and it pays scatter wins and triggers free spins. This double duty symbol is important because any time you see two books you are in sweat mode for that third one. Scatter hits are not super frequent thanks to the high volatility, but when they land the energy goes up fast.
  • FreeSpins: Hit 3 or more Book scatters and you get 10 free spins. That is the main bonus in Book of Merlin and the whole game is basically a speedrun to this feature. The trigger is not easy, expect dry spells, but the free spins can absolutely print if the setup is right. You can retrigger with more books during the feature for extra spins, which is huge for stretching those hot streaks.
  • Expanding Symbols: At the start of the free spins round a random symbol is chosen to become the special expanding symbol. When enough of that symbol land on a spin, they expand to cover their entire reels and pay on all 10 lines even if they are not next to each other. This is where the Book of Merlin bonus features go from chill to insane. Low symbols expand more often for steady wins while high symbols like Merlin are rare but can drop full screens that feel completely broken in a good way.

Max Win Potential & Payouts

The official older info points to a Book of Merlin max win around 5000x, while your database claim says up to 225000x which would be absolutely wild. Either way this game is clearly built for big win hunters, not for slow and steady grinders.

The base game is mostly a bridge to the bonus. You will get some nice Merlin lines and book wild connections here and there, but the real money is in the free spins with the expanding symbol. Full screens of premiums can nuke the board in one go. If you are chasing how to win big on Book of Merlin, it is basically full screen or stacked expanding hits during the feature.

Because the volatility is maxed, do not expect constant medium hits. You can spin a while with not much happening, then one bonus turns the whole session around. If you want consistent small payouts this will feel like a major L. If you live for that one insane clip moment, this is an S tier pick.

The Vibe Check: Aesthetic & Energy

Visually Book of Merlin is clean. Transparent reels, stacked books, glowing potions and Merlin chilling in his wizard lab. It is got that fantasy theme locked in without looking like every other Egypt book clone. The symbols pop nicely, from the basic 10 to A royals up to the wand, amulet and potion bottle.

The soundtrack is low key mystical, more cozy wizard library than full rave, but it matches the vibe. Spins feel crisp, wins land with satisfying pops and the expanding symbol animations during free spins are super clutch for hype. You definitely get that main character energy when the chosen symbol starts stretching across the reels.

Final Verdict: Play or Skip?

Book of Merlin is a strong pick if you are into high volatility book style slots and want a fantasy wizard spin on the formula. The gameplay is simple but the free spins with expanding symbols bring serious win potential and streamer worthy moments.

On the flip side the 95.8 percent Book of Merlin RTP is slightly below average and the base game can feel dry. The bonus is not easy to trigger so be ready for some patience and a decent bankroll if you are pushing higher bets.

Who is this for. Big win chasers, fans of Book of Ra style mechanics and anyone who loves a magic fantasy theme will vibe with it. If you just want chill low variance gameplay this might feel too brutal. Overall Book of Merlin from 1x2 Gaming is closer to fire than mid, but it is definitely a high risk high reward experience. Spin it if you are ready for wizard level volatility.

✓ Pros

  • Classic book style gameplay with fantasy wizard twist
  • High volatility with serious big win potential in free spins
  • Expanding symbol mechanic keeps bonuses super hype
  • Clean visuals and cozy magic theme that feels fresh vs Egypt clones

✗ Cons

  • RTP at 95.8 percent is slightly below average
  • Base game can feel dry and repetitive
  • Bonus can be hard to trigger so bankroll swings are heavy
  • Only one main feature so not ideal if you want lots of side mechanics

Bottom Line

Book of Merlin from 1x2 Gaming is a high volatility book style slot that leans hard into fantasy wizard vibes and big bonus potential. The 5x3 grid with 10 fixed lines keeps things simple, while the Book symbol doing wild and scatter duty plus the free spins with expanding symbols deliver the real hype.

The Book of Merlin RTP of 95.8 percent is a bit on the low side and the bonus is not easy to trigger, so this is not a chill session game. But if you are chasing huge hits and love that one bonus that changes everything, Book of Merlin is absolutely worth a spin. Play it for the expanding symbol free spins and full screen dreams, skip it if you want low risk steady payouts.
