Secret Code is a 5 reel, 20 payline slot from Net Entertainment that is only available to play on desktop devices (like laptops or PCs). Playable from 20p to £100 per spin, this game is based on hidden secrets and mysteries of the Illuminati as it portrays the symbolism of the elite.

This dark slot comes with a haunting soundtrack where you will hear chanting monks with the wind whistling through the corridors of an ancient stone castle – it may look a little dated but Secret Code holds plenty of value.

Look out for the wild symbol (a cloaked man holding a knife) as he substitutes for all symbols except the scatter and bonus symbols. Now, it appears on the 3 middle reels and expands to cover the whole reel when part of a winning combination – if you get 3 fully wild reels, prepare yourself for huge wins.

There is also a Bonus feature where you are brought into the fold of the secret society – it’s activated by getting the key and lock bonus symbol on reels 3, 4 and 5. You are taken deep into the gothic corridors of power where masked statues hide their truths – will they be angels or demons?

You are presented with 5 masked statues holding chests and a set of 5 keys – they key is to match the keys to the chests. If you do, you will reveal an angel with a cash prize awarded. If you unveil a demon, you won’t win anything. You can then choose the gamble your entire winnings, half or none of it.

The main attraction is the Free Spins feature which is played when 3 or more scatter symbols appear anywhere on the reels. You then choose a scatter to reveal the number of free spins and the multiplier you’ll play with. There’s up to 12 free spins to be won here by the way.

During the feature, you can benefit from an increasing multiplier – 2 or more scatter symbol will reveal the multiplier by the number of scatters shown. If you were to get 4 scatters, the multiplier would go up by 4. The maximum multiplier can reach 20x!

In terms of the variance, I found Secret Code to be medium to high variance – there’s a massive 28,265 times your stake to be won which will come in the Free Spins feature due to the potential 20x multiplier. There’s also big wins available in the base game due to the 3 expanding wild reels you can get. If you like Secret Code, I also recommend you try NetEnt’s other older slots with Piggy Riches and Victorious excellent choices.
