Page updated July 2026
Magic Merlin Megaways is a 6-reel Arthurian-themed slot from Storm Gaming, a British developer better known for its land-based cabinet business than for online releases, and this was the studio's first venture into the Megaways format. Built under licence, the game can generate up to 117,649 ways to win when the reels expand to their fullest.
Set in a world of wizards, castles and Arthurian legend, Magic Merlin Megaways pairs tidy, well-drawn symbol art with a cascading reel system, so winning combinations clear from the board and new symbols drop in to potentially chain together further wins on the same spin. An extra reel element, referred to in-game as the Marvellous Mechanical Symbol Generator, adds supplementary symbols into the mix to boost the chances of landing a combination, while a mystery symbol can appear at random and transform into a matching pay symbol across the grid. The free spins round builds on this further with an unlimited win multiplier that climbs after every cascading reaction, which is where the game's real long-term potential sits.
Magic Merlin Megaways returns 96.36% to players over the long run, a figure that sits above the industry norm and suggests a fair payout structure once the swings of any individual session are averaged out.
This is a high-volatility slot, so players should expect the cascading wins to come in bursts rather than a steady drip, with quieter stretches offset by the potential for the free spins multiplier to build into something substantial. The theoretical hit frequency sits at 36.97%, meaning just over a third of spins produce some form of return, which helps keep the base game from feeling too dry between the bigger features.
Storm Gaming hasn't published a confirmed maximum win multiplier for this title, so rather than estimate a figure, it's worth checking the in-game information screen for the current top prize cap before you dive in. Stakes run from 0.20 up to 100 per spin across desktop, tablet and mobile.
Magic Merlin Megaways takes a well-worn wizard theme and gives it a competent Megaways treatment, with the expanding grid, mystery symbol and unlimited multiplier free spins doing enough to justify a spin. The 96.36% RTP and high volatility make it a reasonable choice for players who enjoy cascading mechanics and don't mind waiting out quieter patches for the free spins to build momentum. As always, the free demo at johnessyslots.com is the easiest way to see the Megaways grid and multiplier feature in action before committing real stakes.
