Merlin's Grimoire


Unfinished Games

If your game round is disrupted, all game information and placed bets are stored until you reopen the game. You may continue your unfinished round from the point of interruption. Unresolved bets placed but remaining undecided in incomplete games will become void after 7 days. Malfunction voids all pays and plays.


Way wins are awarded for adjacent symbol combinations, according to the information in the paytable and game rules. When winning on multiple ways in a single game round, all winnings are added together. All winnings from Features (such as Free Spins), Bonus Games and/or Scatters (if applicable) are also added to way wins. All winning combinations are paid out at the end of a game round. Free Spin features are played with the same bet as the game round that triggered the feature – unless otherwise stated. The bet cannot be changed during a currently running game round. Please refer to the game rules for more information.

Game Rules

MERLIN'S GRIMOIRE is a 5 by 3 video slot game with 243 payways (7776 with symbols split on all reels).

There is a random chance to activate symbol splitting reels, in base game these can be reels 2, 3 and 4. During FREE SPINS all 5 reels can be activated. Winning with a split symbol doubles up the payways for that win.

WILD SCATTER symbols can land on any reel. 3 or more WILD SCATTER symbols can trigger FREE SPINS with an initial 10 rounds. FREE SPINS can be re-triggered with 10 additional FREE SPINS awarded up to a maximum of 5 times, by landing an additional 3 or more WILD SCATTER symbols during FREE SPINS.

Before FREE SPINS begins, a symbol is chosen from any of the high or low-paying symbols to become a Special EXPANDING SYMBOL during the entire FREE SPINS sequence. After prizes for regular winning combinations have been recognized, the Special EXPANDING SYMBOL may expand to cover all three positions on its reel. This symbol will only expand when it is part of a winning combination. The Special EXPANDING SYMBOLS do not need to appear adjacent to each other to result in a winning combination.

The average RTP is 94.20%. RTP is achieved through participation.
