Theme and Design
Merlin Is Tracking Down A Beautiful Enchantress
Play n Go add another slot game featuring the magician Merlin to their catalogue. This guy has cropped up in previous slots of theirs, including Merlin’s Grimoire. The storyline here involves his dalliance with an Enchantress. She appears in a forest glade in the intro clip before disappearing, as if by magic. We can only assume Merlin will now try to track her down. The vibe is (not surprisingly) magical and ethereal. It’s all quite charming, with nice sounds and visuals, a little at odds with what seems to be a pretty volatile engine.

RTP and Variance
Merlin Realm of Charm has 5 RTP rates – 96.2%, 94.2%, 91.2%, 87.2% and 84.2%. It’s not unheard of for UK slot sites to run Play n Go slots at under 90% RTP, so watch out. I recommend playing at MrQ from Lindar Media which consistently runs slots at optimum RTP rates, in this case, 96.2%. You can check the RTP for yourself by hitting the ‘?’ link at the foot of the game screen then scrolling down until you see Return to Player.
This is a high variance slot, and Play n Go can make their games volatile, so keep that in mind when choosing your stake as Merlin can burn you.
Maximum Win
The max payout from a single spin here is 10,000x or £10,000 from a £1 bet. That’s not bad potential. Play n Go aren’t known for their huge payouts, though occasionally they produce games with higher max wins like Kiss Reels of Rock (50,000x) and Clash of Camelot (35,000x).
Symbols and Paytable
Merlin Realm of Charm plays on a simple 5 reel and 3 row reel set with just 10 paylines in play. You’ll need to land 3 or more identical symbols on a line from left to right, starting at the left most reel, to score a win.
There are 9 pay symbols in the table. The low value ones are the rune icons that look vaguely like cards, valued up to 0.6x for 5 on a line. The premiums are the sword, crystal, apple and merlin. These are valued at up to 10x for 5 merlins on a line.
You’ll also notice a red-headed Enchantress character who acts as both the Wild and the Scatter. She will substitute for any standard pay symbol to complete a payline.
Features and Gameplay
Merlin Realm of Charm includes expanding symbols and free spins. This is how it works.
Enchantress Scatters Trigger Free Spins
You need to land 3 or more Enchantress symbols on one spin to tigger free spins. Remember, she is also the wild, so a powerful symbol.
One Symbol Becomes An Expander
Before your free spins start, one symbol is chosen as the Expander. If you don’t like the symbol that was chosen you can try for another, but you may find you end up with one of a lower value, so beware.
When the expander lands, it is sticky for the rest of the round, but it doesn’t expand UNTIL enough are visible to create a win. At that point, they ALL expand.
You can extend the round by landing 3 or more Enchantress symbols once again. That will get you 5 more spins, with a maximum of 30 spins available.
Gamble Your Wins
Finally, a gamble feature has been thrown into Merlin Realm of Charm, activated EVERY time you win. The gamble is on a card turn, to double by guessing the color, or quadruple by guessing the suit.
You can gamble up to 5 times, but keep in mind that losing will mean forfeiting the prize entirely.
Final Verdict
Merlin Realm of Charm has strong ‘Book of … ‘ vibes as any regular slots player will have noticed. Expanding, sticky symbols in the free spins round are what drives games like Book of Dead, also by Play n Go, and they are the main event here too. And like those games, Merlin packs all its punch into the bonus feature where spectacular results are possible if you can keep re-triggering with a bunch of high value expanded symbols stuck on the reels. The downside is, to balance things out the base game lacks any real thrills. In short, this slot is built for the pure gamblers out there ready to take risks and be patient chasing down the big win moments. If that’s you, then Merlin Realm of Charm is one you should try.
Testing Notes
I played 250 spins on Merlin Realm of Charm on Play n Go’s test server prior to release to test the game. This is what happened.
- Stake Size: 1
- Start balance: 25,000
- End balance: 24,990
- Hit Rate: 32% (80 winning spins in 250)
- Biggest Win: 77x
- Free Spins Round: 2
Merlin Realm of Charm’s win rate was impressive at 32% with 80 winning spins in 250. That is unusually high for a high variance slot, but it’s offset by the fact that many of those wins were small. The reason for that is there is nothing in the base game to enhance the value of wins – no multipliers or symbol splits for example. But nevertheless, the game rattled along at a good pace, and having a high win rate kept me interested whilst waiting for the free spins to trigger.

That happened twice for me in 250 spins which is a good result. And both times the win was good – 62x and 77x. I had just 5 spins but if you land expanders early on you’ll do well because they stick so you win on every remaining spin. And that’s it. It’s not a complex slot, but the fun theme, regular wins and powerful bonus feature were enough for me in this short session.
