Secret Symbol Slots

To this day, people around the world remain fascinated by ancient and lost cultures and civilizations. Archeologists and treasure hunters alike get excited each and every time they visit an ancient ruin or a forgotten city, hoping to dig up amazing and valuable treasures – whether that’s just to learn more about these people of the past, or to find an instant fortune.

That’s the atmosphere you’ll find throughout Secret Symbol, a brand new slot machine created by Realtime Gaming (or RTG). In this game, players will explore the lost world of the Aztecs, hoping to worth their way through the mysterious symbols these people left behind. Success means not only exciting discoveries, but also the potential to win some huge prizes at the end of any given spin.

Uncovering Secrets

Secret Symbol is a 25-payline, five-reel slot machine that can be played at sites carrying the RTG software package. The object of the game, as usual, is for players to match identical symbols from left to right across their active lines. The game is available in all of the RTG platforms, including their mobile, instant play, and downloadable clients.

Players earn prizes by matching thematic symbols across the reels, with longer matching earning bigger rewards. Prize amounts can get rather large in this game, with prizes as large as 50,000 times the bet per line available. In addition, there are some special icons that players can look for in order to enjoy some additional benefits.

For instance, there is an Aztec Chief that can appear on the reels, acting as a wild substitute. This can take the place of any normal prize-winning icon in order to help make winning combinations.

There is also a pyramid that acts as a scatter. This pyramid can also trigger a bonus round in which players can enjoy 10 free games. Known as the Secret Symbol feature, this game comes with a great number of additional perks for players. For instance, each spin comes with a secret multiplier that can range from 2x to 20x, and applies to all wins. However, players won’t know until after each spin what their multiplier will be. In addition, the Aztec Chief can expand to cover all of the second and fourth reels, and players also have the potential to retrigger the free spins.

Random Bonuses Add More Excitement

This is also one of the many machines from RTG that offers up random progressive jackpots that players can potentially win on every spin. These jackpots are awarded independent of the result of each round of play: players can be awarded the Major or Minor jackpot after any game, making for a nice added surprise after the initial prizes have been awarded. At most casinos, the Major jackpot begins at $1,000, and the minor at $250, and increases as players play for real money on the machine.

Deciphering the Symbols

If you’ve ever wished you could uncover the secrets of an ancient civilization, then Secret Symbol is the game for you. With a free spins round that offers up plenty of surprises, progressive jackpots, and a theme that’s both interesting and fun, this is a new machine that we think many slots fans – especially those who already enjoy RTG casinos – will definitely want to give a try.
