What hooked me in Rise of Merlin is the expanding symbol mechanic. You trigger free spins by landing three or more crystal balls, which choose a random symbol that can fill entire reels and set up bigger wins. This 5-reel, 10-payline Play’n GO slot runs at 96.58% RTP and is high volatility, with up to 5,000x possible on a single spin.
If you’re a fan of bonuses that snowball with retriggers and build suspense on every spin, you’ll want to give this one a shot. Short bursts of tension, then big paydays if it hits.

Rise of Merlin uses a 5×3 reel grid with 10 fixed paylines. Wins pay left to right only. You can choose spin amounts from 0.01 up to 100, with all 10 lines active at all times.
The crystal ball symbol acts as both wild and scatter. It substitutes for other symbols and triggers free spins when three or more land anywhere on the reels.
There’s also a game feature after any win. You can try to double or quadruple your payout by guessing the color or suit of a hidden card.
Rise of Merlin has a published Return to Player (RTP) of 96.58%. This means that, over many spins, the slot is programmed to pay back 96.58% of all plays, which is above the industry average. For more slots with strong payout percentages, check our high RTP slots list.
The slot is generally rated as high volatility. High volatility means that big wins are possible, but they may come with longer dry spells between payouts. This suits players who enjoy the risk and reward balance of waiting for a major feature or payout. There is no published hit frequency for this title.
All wins are paid for matching symbols left to right along the 10 fixed paylines. Payouts below are multiples of the line spin.
| Symbol | 3-of-a-kind | 4-of-a-kind | 5-of-a-kind |
|---|---|---|---|
| Merlin | 100 | 1,000 | 5,000 |
| Crystal Ball (Wild/Scatter) | 100 | 1,000 | 5,000 |
| Red Dragon | – | – | 1,600 |
| Owl | – | – | 600 |
| White Dragon | – | – | 600 |
| A, K, Q, J, 10 | – | – | – |
During free spins, any chosen expanding symbol can fill entire reels and pay on all lines, even if the symbols aren’t adjacent.
The maximum win in Rise of Merlin is 5,000x your total spin. This happens when you land a full screen of either Merlin or crystal ball symbols in the base game or free spins. Expanding symbols in the bonus round make it more achievable.
There’s no way to force or tweak when the free spins bonus drops in Rise of Merlin — the random number generator decides every spin. When I ran the demo, it reminded me just how rarely the free spins trigger, but when you do land retriggers, your chances genuinely multiply with each new expanding symbol.
I’d keep my spin size small at first to stretch your playtime. The free spins bonus comes and goes in streaks. If you’re patient, that’s when things can heat up fast.
If you use the game feature, remember that every double-up attempt is a 50/50 or 1-in-4 shot. Past spins never affect future outcomes, so always treat each round as independent.
Big hits or long droughts — there’s not much in between.
Rise of Merlin opts for a 2D fantasy art style with detailed character and beast symbols. Behind the reels, you’ll spot a magical hall full of glowing pillars and swirling energy.
Landing a major win triggers flashy magical effects and glowing symbol animations. The soundtrack instantly sets the fantasy vibe, with orchestral flourishes and shimmering note effects on feature triggers.
Animations run smoothly, keeping up a magical atmosphere from start to finish. Bonus round sounds deliver a suspenseful kick. It’s a strong look and sound combo.

Slots are built for fun, not as a main way to get prize pools. Setting a limit on how much you put in, using session timers, or hitting pause with self-exclusion tools can help you keep it light. If spinning ever stops being fun or gets stressful, it’s time for a break. There’s support out there when you need it.
Rise of Merlin is a winner for anyone who’s into high volatility slots with those big, feature-driven swings. If you like “book” style play — expanding symbols, retriggers, and free spins that can spiral into huge wins — this one puts all those features under a fresh magical theme.
The best part of the game is easily the free spins. Each retrigger tacks on an extra expanding symbol, and when the bonus builds, things get really exciting. Watching two or even three symbols explode across the grid sends the suspense through the roof.
You’ll want to be prepared for dry spells, though. The highs are high, but you might go a while before the free spins bonus hits. Some may find the base game a grind if they’re short on patience or play on a limited budget.
I’d try the demo first. See if Rise of Merlin’s tempo and bonus rhythm fit your style, then chase the big rewards if you feel up for it.
Big risk, big moments. That’s the package.
