Merlin’s Alchemy: Slot Overview

Put David Copperfield, Harry Houdini, and even Uri Gellar’s spoon tricks to one side for a second. In the world of online slots, the spellcaster who most often shows up is Merlin of Arthurian legend. Here, he’s materialised in Bullshark Games‘ online slot Merlin’s Alchemy, powered by Hacksaw Gaming. It’s an alchemy-themed scatter paying slot loaded with special symbols, topped off by a persistent multiplier during the Spellbook Free Spins round that can, when everything lines up, turn a modest lead-like bankroll into something far shinier.

Depending on which version of the tale you follow, Merlin is usually placed alongside King Arthur many centuries ago. Yet the Merlin in this slot looks more like a Victorian-era gentleman than someone living soon after the fall of the Western Roman Empire. In Merlin’s Alchemy, he brings to mind the League of Legends inventor Heimerdinger, holding a potion bottle filled with a strange glowing liquid. Since alchemy’s “lead into gold” idea is often viewed as symbolic rather than literal, it’s hard to say what this bespectacled character is really attempting—and the game’s eerie ambient audio only adds to the intrigue.

On the practical side, gameplay in Merlin’s Alchemy unfolds across a 6-reel, 5-row setup using a scatter-paying system. Whenever at least 8 identical pay symbols land, they form a win, after which the winning symbols are removed and new ones drop in via the cascade mechanism. Bullshark Gaming rates the volatility at 4/5 (medium-high), while the default RTP sits at 96.25%, with a lower RTP version also available. The hit frequency is 24.84%, and stakes range from 10 c to $/€100 per spin.

A look at the paytable shows 10 standard paying symbols: parchment tiles marked 10 through A for the low pays, followed by 5 differently coloured metal lumps as the premium symbols. For an 8 OAK scatter win, payouts run from 0.1 to 2.5 times the bet, while the top end reaches 5 to 150 times the bet for landing 15+ OAK.

Merlin’s Alchemy: Slot Features

Mystery symbols play a major role in Merlin’s Alchemy, capable of transforming into a variety of rewards, including special symbols like multiplier boosts and more. Alongside its base-game alchemy, Merlin’s Alchemy also includes a free spins round, plus three feature buy options.

Mystery Symbols

Mystery symbols can appear in both the base game and free spins. When they land, mystery symbols reveal a random paying symbol or special symbols. Any revealed paying symbols will all match. The special symbols are:

• Wild – substitutes for any paying symbol. If the grid contains only wilds, they pay as the highest-value symbol.
• Activator Wild – applies the Global Multiplier value to any wins it helps create while also substituting for any paying symbol. If more than 1 Activator Wild lands, each one applies the Global Multiplier value by adding the multipliers together.
• Sticky Activator Wild – appears only in free spins and stays in position until the feature ends, functioning like the Activator Wild.
• Green Potion Bottle – increases the Global Multiplier by 1x to 100x.
• Red Potion Bottle – multiplies the Global Multiplier by x2 to x10. Any additive values always apply first, followed by multiplicative values.

Spellbook Free Spins

Landing 3, 4, or 5 FS scatter symbols in the base game awards 8, 10, or 12 free spins. In free spins, the odds of landing mystery symbols are increased, and the Global Multiplier remains persistent until the round finishes. The Global Multiplier begins at x1 unless stated otherwise.

Bonus Buy

The Bonus Buy offers a way to trigger the following bonuses, each of which is highly volatile.

• BonusHunt FeatureSpins – 2x the bet where each spin is 3 times more likely to trigger Spellbook Free Spins. RTP 96.23%.
• Spellbook Free Spins – 100x the bet to trigger 8, 10, or 12 free spins. RTP 96.27%.
• Spellbook Free Spins – 200x the bet to buy 8, 10, or 12 free spins where the multiplier starts from x10. RTP 96.36%.

Merlin’s Alchemy: Slot Verdict

Not long ago, creating a “book of” slot felt like a developer’s rite of passage—a must-have item to be taken seriously, like owning a pair of white-toe Converse Chuck Taylor All Star. Nowadays, as of writing, the must-have trend seems to be the scatter-paying slot; they’ve become so widespread that players have an enormous selection. So the real question here is: why pick Merlin’s Alchemy over the many alternatives?

The good news is Merlin’s Alchemy rarely missteps, meaning there aren’t any glaring issues to complain about. It delivers a fun alchemical setting, although some of the smaller visual touches—like how win amounts are displayed, or the look of certain symbols—don’t always stand out and could have been executed with more impact. It’s a minor point, but in a scatter-paying market this crowded, details count. Still, those quirks don’t overshadow the game’s strengths, such as plenty of wild activity for a scatter pays title, a win potential of 10,000x the bet, and a fairly smart approach to weaving multipliers into the action.

All told, Merlin’s Alchemy offers a solid scatter-paying session with more upsides than drawbacks. It probably won’t dethrone the likes of Gates of Olympus, and it may find it tough to stand out against the flood of releases from Pragmatic Play and others, but it’s well put together and worth checking out if this kind of slot is in your wheelhouse.
