Merlin and the Ice Queen Morgana is a slot that presents 5 reels, 3 paylines and 10 Ways to Win. You win when 3 or more matching symbols land on a payline from left to right. For a win with higher value symbols, you only need to land 2 of them.
Low value symbols are available for A, K, Q, J, and 10 Royals. High value symbols are rings, cauldrons, spell books and Merlin. Look out for this last one in particular: if you manage to land Merlin, you can win up to 250 times your stake.
This slot machine also has a Wild symbol, namely Morgana. She can appear on any reel and pays out up to 250 times your stake. In addition, it replaces any other symbol.
The Scatter symbol is depicted by Merlin's staff. Landing 3 or more will trigger the free spins. Became curious? 

Merlin and the Ice Queen Morgana comes with no less than 2 bonus features, namely multipliers and free spins. Both features offer a pretty big win next to the base game. You have the opportunity to win up to 20 free spins. 

If you manage to get the Morgana Wild symbols stacked on the series, you activate the Morgana Multiplier. That means that a 2, 3, 5 or 8 times multiplier is triggered, randomly. Any winnings that land during a spin will benefit from this. The Morgana Multiplier feature can be activated both in the base game and during the free spins feature.

When you land 3 or more Scatters with Merlin's staff on them, the free spins feature starts. You get 10 free spins anyway, and 3, 4, or 5 winning symbols guarantee a win of 1, 10 or 100 times your stake. What is special about the bonus round of this slot is that before the free spins start, a random symbol is named an Expanding symbol. That can have a low or a high value. We know this bonus from well-known slot machines such as Book of Ra deluxe and Book of Dead.
