Where to play?

Secret Symbol is a 25 payline, 5 reel progressive jackpot slots powered by RealTime Gaming. The theme of the slots is about the once mighty Aztec culture a Pre-Columbian Mesoamerican people of central Mexico who lived between the 14th and 16th centuries.

They also called them Mexica from which the Republic of Mexico’s name is derived. We provide some valuable tips when playing a progressive jackpot slots on this page:

“Secret Symbols is pure gold, since it is a progressive jackpot you can really hit it big and get your hands on Montezuma’s fabled treasure. With the help of the geniuses at RTG, Secret Symbol shows that it’s games are just getting better and better.”

There are several reasons for the decline of the Aztec empire, scholars reckon that between 1517 and 1519 the Aztec city of Tenochtitlan experienced a massive earthquake which in turn caused lake Texcoco to flood the capital city.

The other reason for their demise is the arrival of the Spanish explorer Hernando Cortes in 1517, as they say the rest is history. Secret Symbol slots was released on the 15th March 2017, it celebrates the once mighty Aztec empire. As far as realistic audio goes its jungle-inspired soundtrack blew me away while the game comes with scatter (pyramid) symbols that initiates the free spins feature.

The theoretical return to player percentage (RTP) of Secret Symbol is 95%, come to think of it’s really not that bad for a progressive slots. If you play the same game at a land-casino you’re looking at a house edge (HE) of 9%, maybe more. The symbols that appear on the reels remain true to the theme of the game; you’ll see parrots, snakes, totem pole, necklace, a black panther (revered by the Aztec’s) and a pyramid. Since it’s a progressive jackpot slots players can snag some big wins here!


Game Play

The coin range is 0.01 up to 1.00, it’s a progressive make sure that you have a decent seized bankroll when you play it. Wins don’t come easy but if they do come along it’s a pretty penny.


Bonus Modes

There’s a couple of lucrative features that keeps the bankroll ticking over nicely. For one there’s a substituting wild, scatters and a decadent free spins mode.


The wild symbol is the Aztec chief, it completes a winning combination when it replaces all the other symbols except the scatter. Hit 4 or more wilds on an active line and you’ll be smiling from ear to ear.

Free Spins

The free spins feature is triggered by three or more Pyramid scatter symbols. Once the feature is triggered not only will you receive a bunch of free spins (10 free spins) but each free spin win comes with a multiplier win of up to 20x! Keep in mind that this is a progressive so triggering the free spins feature won’t be easy, if you do expect some decent wins.



RTG’s Secret Symbol progressive jackpot slots allows you to experience heart-pumping Vegas-style action that’s flushed with mesmerizing visuals and a lucrative free spins feature. It’s one of those games that doesn’t deserve a spin or two but a whole bunch, it’s not only about the big wins but the entertainment it offers is simply top notch.
