After all, whoever has read these works of his knows far too well that all of them feature some sort of secret codes, as well as mystifying symbols. It is precisely those which seem to be the driving forces behind this NetEnt slot, suitably given the title “Secret Code”. If you happen to be a mystery lover yourself, and already feel somewhat intrigued by the sound of this slot, then you can read the complete review below.

Theme, Symbols, and Betting Options


This 5-reel online video slot features 20 paylines. As for the reels themselves, they spin in front of a backdrop, which seems to be a piece of parchment and contains various sketches. Dare we say, these drawings are quite reminiscent of the drawings of the great Leonardo da Vinci himself, and this fits in perfectly.

In fact, when it comes to the symbols, no just the background, all of them related one way or another to the overall theme: to archaic symbols and signs (nope, you won’t be looking at any boring Playing Card Symbols here). There are also these green, blue, and purple seals; then you get some yellow, red, and green rings, as well as a book & magnifying class, a sand timer, and even human characters including a red-jacketed gentleman and a blonde-haired lady.

Far be it for us to forget about the special symbols offered in this slot. This means a Scatter symbol that shows the mysterious letters X.O.R.N.S.T.O, and even a key placed in a lock representing the bonus symbol. Don’t worry, there’s a Wild Symbol here too, and it is represented by a mysterious-looking hooded character. We’ll discuss these further below.

Overall Rating

This is truly a fantastic-looking online video slot from NetEnt which has been clearly based on Dan Brown’s world-famous works. It even offers up a suitably religious, dramatic soundtrack, plus the bonus games will surely keep you well interested. Don’t take our word for it, try it out yourselves on one of our top-rated online casinos. We wish you the very best of luck!
