Mysterious is a variable reel size video slot with 4096 ways to win. The player gets to interact with 18 symbols: 9 regular ones, 1 Scatter, 7 WILDS and 1 overlay symbol. The WILD symbol has a different appearance depending on its features and type, and it substitutes all symbols except the Scatter one, which can be added dynamically to the reels.
The game includes a series of features that make it highly lucrative and enjoyable in terms of player experience. The Lord feature makes any WILD that lands on the reels to reveal a multiplier. The Lady feature makes any WILD payable and a stacked mystery symbol will be revealed after its apparition. The Bardon feature makes it possible to land three WILDS onto the reels. The three symbols can influence the other ones nearby and transform them into WILDS as well, increasing the chances for big wins.
Moreover, Mysterious features a Bonus Activation function with dynamically added Scatters and the chance to win numerous Free Spins. Players can choose between Resurrected Wilds (Free WILDS) and the Clock Multiplier (Free Scatters). During the Free Game mode, the reels set is changed, and once it ends, the player gets to continue the game with Lord, Lady or Baron.
