About Codex
Spieldev’s Codex slot machine is slow to start up, and that is a bad sign. This usually means that you are going to be greeted with a high-intensity graphics slot, and whilst that is greats for players on newer hardware, those with older phones, tablets or laptops may struggle to play this game without choppiness. As for the slot’s theme, Spieldev have chosen to go down a very basic route with this slot. There really isn’t one, save for the odd big of mechanical mysticism. Codex is played over a total of 5 reels and 20 paylines, none of which can be altered by the player. Players can, however, alter their total bets. These range from a base minimum of 0.20 per spin, up to a capped maximum wager of 100.00 per spin. Codex will see players able to win prizes which are worth up to 1,000 coins in total.
Special Features
The wild symbol is represented by a green emblem in this game, and as a wild it can substitute for all other symbols in the slot, barring three. Wilds cannot replace Vault Bonus and free spin symbols. They cannot replace Invention Combos either. Wilds have no cash values of their own to offer players.
Invention Combo symbols appear as star, triangle or whirl-shaped symbols. These can randomly boost your winnings by 4x, 5x or 6x your total bet when all 3 symbols are used in conjunction with one another.
As for the free spin bonus round, players need to land 3, 4 or 5 of the free spin symbols in order to trigger a total of 7, 10 or 12 free spins, respectively. Free spin symbols can appear on any reel and be retriggered indefinitely. Vault symbols do not appear during this bonus round. During the free games bonus, any symbol can also be randomly turned into sticky wilds. The greater the number of spins you get, the more likely you are to bag plenty of sticky wilds.
Bonus Feature
Players who land 2 vault bonus icons on the reels of the game will trigger a Vault Trail bonus. These symbols can only appear on the second and fourth reels of the game. Once the bonus begins, a 5-reel Cryptex starts. You will need to guess the right combination. Players can unlock the reels in order, one at a time and can pocket spins for every successfully unlocked reel in this bizarre feature. Players can also buy re-spins, which will change the prize expectancy, but prizes could range as high as 195x the total bet with this nutty and overly complex feature.
