Net Entertainment presents a slot machine with a mysterious theme. The hidden secrets of the Illuminati are represented in the Secret Code game and the elite is shown through various symbols. Gothic corridors can be seen alongside the five reels and every spin will show three rows of symbols players can use to win prizes. A maximum of 20 lines can be activated in this slot and they will allow winning combinations to be formed as long as they start from the leftmost reel. The wild symbol is shown as a man with a knife and it can substitute for regular symbols. Wild icons appearing on reels 2, 3 or 4 will expand to take up the entire roller for three positions if there is a winning bet line present. The scatter is a mysterious lock and three of them or more are needed on the screen at the same time to activate free spins. The wins obtained here will be multiplied by an amount between 1 and 20 and the multiplier can be increased by getting two or more scatter symbols during the free spins. Bonus symbols represented by a keyhole and a key will start the bonus game when they appear on reels 3, 4 and 5 at the same time. A mini-game will appear as a bonus and the player must select which chests to open in order to get the prizes and see if the masked statues are angles or demons. Once the bonus game is over, players can choose to enter the entire winning amount or half of it in a game of chance for more wins. The other symbols show an old man looking to unravel the secret code, a young woman, an old book, an hourglass, three rings and three stones with different symbols and colors.
