Secret Symbol Graphics and Audio

Overall, we were very happy with the graphical presentation in Secret Symbol. Behind the reels is a gorgeous backdrop of the rainforest with a waterfall. Everything about the visuals is crisp and sharp, making this a very attractive slot game. The same thing can be said about the symbols on the reels themselves, with bright and attractive colours.

The audio was spot on as well. The background sounds of the jungle are very impressive, which always helps to make a slot more immersive. The symbols themselves include Aztec jewelry, pyramid, wildlife, and other things associated with the theme.

Secret Symbol Gameplay

With top-notch visuals and sounds, we were wondering if the gameplay would keep the high standards. Luckily, it does. The game has a ‘return to player’ of around 95%, which is really not bad for a slot with a progressive jackpot.

The betting range on coins is from 0.01 up to 1.00, but players should try to make sure they have a decently sized bankroll for this game. We found that wins don’t happen as often as many other slots, but they’re bigger when they do happen.

Players will also find a wild, and a scatter. The wild is represented by an Aztec Chief, and it will replace other symbols to form winning combos.

Then there is also a free spins bonus, triggered by the scatter symbol. The scatter is represented by the Pyramid symbol and landing three or more scatters will give players ten free spins. The free spins also come with a 20x multiplier, so the wins will be impressive.

Secret Symbol Conclusion

We were very impressed with what RealTime Gaming has created with Secret Symbol. The visuals are superb, and the gameplay is fun. The free spins are difficult to trigger, but very lucrative if players are able to get them. This is a very good slot that players should try if it appeals to them and it’s a worthy addition to RealTime’s library.
