Play'n GO's Rise of Merlin invites players into an ancient realm where magic and mystery intertwine. The gameplay follows a familiar 5-reel, 3-row setup, offering 10 adjustable paylines. What distinguishes this slot is its focus on expanding symbols during the free spins feature, a mechanic that can significantly alter the potential for wins on any given spin. The game operates with a theoretical RTP of 96.53%, and its high volatility suggests that while wins may not occur frequently, they have the potential to be substantial when they do align.
The core appeal of Rise of Merlin lies in its dynamic bonus round. Triggered by landing three or more Scatter symbols (represented by Merlin himself), players are awarded 8 free spins. Before the free spins commence, one symbol is randomly selected to become an 'Expanding Symbol' for the duration of the feature. If this chosen symbol appears on a payline during a free spin, it expands to cover the entire reel, creating opportunities for multi-line wins. This mechanic, combined with the potential for retriggers which grant additional free spins and a new expanding symbol, adds a layer of excitement and unpredictability.
For those new to the game, understanding the role of the Expanding Symbol is key. It's important to note that this expansion occurs only when it contributes to a win. This means that even if the symbol appears, it might not expand if it doesn't form part of a winning combination. A practical approach for new players might involve familiarizing themselves with the paytable to understand which symbols have the higher potential for expansion and how they can contribute to larger outcomes.
