Secret Symbol is another RealTime Gaming online slot that was released in 2017. This particular game was first available to play in mid-March 2017. The game has an Aztec theme, which will appeal to many players. People are fascinated with ancient civilizations, so we’re sure the theme will go down well. The game features 25 paylines and five reels, along with a progressive jackpot. Find out if we recommend this online slot by reading our full slot review below.

Secret Symbol

We hold no screen of Secret Symbol in our own files and we do not borrow one from elsewhere, so the plate above carries the title, not the game screen. What the reels do is described below.

Where to spin this title

Three rooms from the top of our own US list, with the welcome offer each one shows at its cashier rather than on a banner. We do not track lobby line-ups day to day, so check the game list once you are inside; the wagering and the catch of each offer sit on our review of that room. Partner links · 21+.

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.

Reading the paytable before you spin

Every screen a player needs for this game is inside the game itself. The paytable lists the symbol values, the number of paylines, the way the feature is triggered and the return range the studio publishes for the title; the same screen opens in demo mode without a deposit and on a phone as well as on a desktop. Reading it first answers the question a review cannot: whether the game pays small amounts often or rarely pays large ones.

Two settings sit next to it and are worth checking in the same minute: the coin value against the number of lines in play, which together make the real stake per spin, and the autoplay limit, which is where a session length is decided rather than guessed.

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.
