Codex is a unique online Slot inspired by the cryptex device invented for Dan Brown's novel, later a film starring Tom Hanks, The Da Vinci code. The hollow device is constructed of spinning reels, which will unlock and reveal its contents if the right combination is entered – an apt device on which to base an online Slot.

This theme gives Codex a unique functionality that makes it different to a standard online Slots reel setup. Instead of spinning reels simulating the reels of a Slot machine, Codex boasts a dismantling and reassembling reel functionality. This means that each cell on the 5x3 reel grid spins independently of other cells, giving each spin a new wealth of possibilities.

The symbols on Codex's unique reels are somewhat unique themselves. While traditional Slots symbols of card ranks can be found as you play, they are joined by other mysterious symbols such as keyholes, as well as three Invention symbols. These complex, geometric diagrams act as normal symbols but can also trigger the Invention Combo feature. Land three different Invention symbols on any winning payline to receive a reward of 4x, 5x or 6x your win.

The Vault Trail Bonus is the ultimate cryptex Slots feature, giving you the chance to open up the five-reel cryptex by hitting the right combination of symbols. For each cryptex reel you unlock, your prize will increase – and you get one free spin per reel, to boot. For the second through fourth reels, you can even buy additional spins. It's a purchase worth considering, because opening the cryptex will reveal what's inside: a prize worth up to 195x your bet.

Finally, landing Free Spins symbols on the reels will unlock the Free Spins bonus feature. This gives you a set of free spins at your current stake, which can re-trigger indefinitely, and during the free spins all wild symbols will be sticky and held in place on the reels.
