Merlin Realm of Charm is a video slot developed by Play'n GO, set in a world inspired by Arthurian legend. The game features the wizard Merlin and a mysterious enchantress. The slot has a classic layout with 5 reels and 10 paylines. The gameplay revolves around making winning combinations of symbols on the reels. These symbols include low-paying rune-like symbols and high-paying symbols such as swords, crystals, apples and Merlin himself.
A key feature of Merlin Realm of Charm is the Free Spins Bonus Round. Get 3 or more Scatter symbols, represented by the Enchantress, to trigger 5 Free Spins. At the start of the free spins, one symbol (excluding the scatter) is randomly selected as the wild symbol. Players are offered a single chance to re-roll this symbol for a potentially more lucrative one.
During Free Spins, the first occurrence of the Special Expanding symbol on each reel becomes sticky and remains in place for the duration of the bonus round. Whenever enough of these symbols land in view to form a winning combination, they expand to cover the entire reel, increasing the potential payout. Expanded symbols do not have to be next to each other on the reels to trigger a win.
The Scatter symbol (Enchantress) is also wild during the base game and Free Spins. This means that it substitutes for all symbols except the scatter symbol during Free Spins to help players complete winning combinations. Landing additional Scatter symbols during Free Spins retriggers the feature, awarding an additional 5 Free Spins, up to a maximum of 30 spins.
Another optional feature is the Gamble Round, available after any winning spin in the base game or after Free Spins. This feature allows players to potentially multiply their winnings by correctly guessing the color or suit of the next card drawn from the deck.
