Any horizontal or vertical line of 3 or more of the same symbol is a winning combination. The best part of the game is without any doubt when you hit Free Spins. This will start a battle between heroes and monsters, giving you the opportunity to get big wins.
High Win Symbols are hero-emblems. Medium Win symbols are the bird faces of our heroes. Low Win symbols represent the heroes’ elements. The Scatter symbol is represented by a symbol reminiscent of the Free Spins wheel. Heroic bird theme FTW!
With the Avalanche mechanic symbols fall into position instead of spinning. A winning spin will trigger an Avalanche™ with symbols in winning combinations explode and disappear, leaving space for new symbols, giving you an opportunity for further wins. And the best part is this won’t stop till you get the winnings going!
The first game presenting this feature is the evergreen from Netent, Gonzo’s Quest.
