Hree or more Azteca symbols mean you get 12 rotations with x3 multipliers. Most importantly, Azteca can be very generous: for example, even during the bonus game, she may offer you a free spin!
Playtech will never tire of the amazing players and let them transfer gambling games. Aztec is just another obvious example. You can't help but notice that it has a strange choice of its own, and it has become more and more fascinating again and again. In a word: enjoy!
