Merlin Realm of Charm includes expanding symbols and free spins. This is how it works.
Enchantress Scatters Trigger Free Spins
You need to land 3 or more Enchantress symbols on one spin to tigger free spins. Remember, she is also the wild, so a powerful symbol.
One Symbol Becomes An Expander
Before your free spins start, one symbol is chosen as the Expander. If you don’t like the symbol that was chosen you can try for another, but you may find you end up with one of a lower value, so beware.
When the expander lands, it is sticky for the rest of the round, but it doesn’t expand UNTIL enough are visible to create a win. At that point, they ALL expand.
You can extend the round by landing 3 or more Enchantress symbols once again. That will get you 5 more spins, with a maximum of 30 spins available.
Gamble Your Wins
Finally, a gamble feature has been thrown into Merlin Realm of Charm, activated EVERY time you win. The gamble is on a card turn, to double by guessing the color, or quadruple by guessing the suit.
You can gamble up to 5 times, but keep in mind that losing will mean forfeiting the prize entirely.
