Rise of Merlin is a five-reel video slot from Play'n GO inspired by Arthurian legends and mythology. The game uses 10 paylines and is classed as a high-volatility title, with a stated return-to-player range of 84.55% to 96.58%. Bets range from 0.01 to 100, and the demo version is available for players who want to play for free and practice before playing for real money.
The central feature is Merlin’s Magical Orb, which acts as both Scatter and Wild. Landing three or more Orbs triggers eight free spins, with each Orb also contributing winnings on the reel. Free Spins can be retriggered, adding another eight spins each time. During the bonus round, one symbol is selected at random to expand, with the number of extra matching symbols required depending on whether it is a high-paying or low-paying symbol.
When enough matching symbols land, the expanded symbol can create additional wins in the same spin. This structure places the focus on symbol collection, free spins and expanding reels-style outcomes, making Rise of Merlin a slot that combines a mythological theme with straightforward bonus mechanics.
