Secret Code

We're going to open this description with an element of slot machines that normally we don't love. And it's the sound. So stay with us here, or scroll down to see the inner workings of Secret Code, the slot game from NetEnt.

Some slots have really great ambient sound – from jungle noises to fun tunes – but then when the gameplay sound starts, it's jarring and makes us mute the whole thing. But with Secret Code, the ambient sound gives way to on-theme gameplay sounds, and even when the reels stop spinning, the ensuing sounds all go together really well. Thank you, NetEnt! OK, we're done. On with the description.

This game has five reels and three rows set in medieval style window frames. There are 20 pay lines, which you can see along the sides of the reels. The minimum bet is .20 credits. The maximum bet is 100 credits per spin. You can adjust the bet lines, the coin value and whether you want to autoplay and bet the maximum in the player dashboard, on the fly.

Icons include various decoder rings, runes, a codebook with a magnifying glass, a witch, and a professor reading from a document.

A cloaked man holding a knife is the wild. Use it to substitute whatever you need for a win. If it helps you get a win on the three middle reels it will expand to cover that entire reel.

Get at least three scatter icons and you'll get free spins. First off, though, you'll have to pick a scatter icon. It will then tell you how many free spins you get and what the multiplier will be.

The lock and key bonus icon on reels three, four and five unlock the bonus game. You'll be taken to a screen with five chests. You'll have five keys. Open the chests to reveal a cash prize or a demon that will take you back to the main game.
