Merlin turns up here looking less like a kindly old storyteller and more like someone who knows exactly how intense this game is about to get. Rise of Merlin doesn’t waste time pretending to be complicated. It takes a very familiar expanding symbol structure, wraps it in Arthurian fantasy, and lets the bonus round do the rest.
That means the base game is mostly about getting to the feature in one piece. Once you get there, the whole thing hinges on which symbol gets chosen and whether the retriggers show up. It’s a simple setup, but simplicity and calm are not the same thing.
Rise of Merlin has gone with a classic fantasy hall backdrop, all arches, stone pillars, and mystical purple light. It’s not a visually overloaded game, which helps keep the reels readable, though it also means the setting feels more functional than spectacular. Merlin, dragons, owls, and the crystal ball do most of the thematic work.
We’ve seen plenty of online slots lean on this sort of wizard and relic imagery, and this one doesn’t try to reinvent it. The strength of this game is in how cleanly it presents everything. The symbols are clear, the background stays out of the way, and the overall atmosphere suits a slot that lives or dies by its feature round.
The lower symbols are the royals from 10 to A, while the premium side is made up of Merlin, the dragon, the owl, and the crystal ball wild.
| Symbol | Payout for 3, 4, 5 of a kind |
|---|---|
| 10 | 5, 20, 80 |
| J | 5, 20, 80 |
| Q | 5, 20, 80 |
| K | 5, 30, 120 |
| A | 5, 30, 120 |
| Owl | 5, 80, 600 |
| White Dragon | 5, 80, 600 |
| Red Dragon | 30, 300, 1600 |
| Merlin | 100, 1000, 5000 |
| Crystal Ball Wild | 10, 1000, 5000 |
Landing 3 or more scatter symbols awards 8 bonus spins. Before the feature begins, one regular symbol is selected as the expanding symbol for that round.
When the chosen symbol lands during bonus spins, it expands to fill the entire reel. This is where the game’s main potential sits, because repeated full reel expansions can create strong line connections across the active paylines.
If 3 or more scatters land again during the bonus spins round, the feature retriggers and another 8 bonus spins are added. At the same time, a second regular symbol is chosen as an additional expanding symbol.
If the feature retriggers again after that, the process repeats, which means the number of expanding symbols can keep growing. That is the main twist in Rise of Merlin compared with the more standard single expanding symbol structure.
Rise of Merlin uses 5 reels, 3 rows, and up to 10 paylines. Wins pay from left to right, and players can choose how many paylines are active. This game is straightforward in the base section, with no elaborate side mechanics or reel modifiers. Everything points toward the bonus feature.
The simplicity in slots like these still has a place across online casinos, especially if the players prefer feature driven slots that do not bury the important part under a pile of side systems. Here, the main mechanical question is not what the slot does, but whether the expanding symbols arrive in useful places once the feature is live.
BetVictor's Opinion
Rise of Merlin knows exactly what it is and doesn’t try to be anything more complicated. The base game is plain, the layout is familiar, and the real interest sits in the retrigger structure that keeps adding new expanding symbols. We wouldn’t call it original, but we also wouldn’t pretend it fails at the job. It is a sturdy, direct feature slot with very little wasted motion.
What stands out most is how the retriggers can steadily turn the round from manageable to dangerous. That is the bit that gives the game its own identity, even if the broad structure is well worn territory by now. When the feature connects properly, it can still make a very convincing case for itself.
