You don’t have to be a genius to decode this Codex mobile slot, just a little bit brave.
We have to admit that this Codex slot looks far more impressive as an online casino game than a mobile phone one.
The graphics feel sharper, the animations flow faster, and it’s just a little bit prettier.
But, that said, the Codex slot on mobile still looks nice enough, with mystical diagrams and Ace to 9 symbols that, if not pop, create an atmospheric feel.
There are two bonus games that you’ll eagerly anticipate.
The first is the free spins, which is a lot of fun, but so hard to find at times, you might wonder if they exist.
The good news is that when you do find them, they tend to be rewarding, thanks to the sticky wilds that stay on screen, like in the Vikings Go Berzerk slot game.
The second is the Vault Trail click me bonus, where you gamble your winnings for more prizes, as you click to decipher what’s behind the Da Vinci Gizmo.
The thing about both these bonuses is that they can be tough nuts to crack. Just because they can pay big, doesn’t mean they will.
With the Vault Trail bonus, the only advice we can really give you is to be a little brave – try and get further along the trail and gamble a little – it’s where you’ll get some decent 100+ wins.
All in all, this SpielDev slot game isn’t exactly revolutionary, but it’s interesting enough to keep you try to figure out if this puzzle box will open up to reveal the best kind of wins.
After all, isn’t completing a puzzle one of the top 10 ways to fight boredom?

Wild Symbol: The green wild symbol is wild and can sometimes come stacked during the main game. It also replaces all other symbols on screen except scatter, vault bonus, or invention symbols for an invention combo.
Invention Combo Feature: When the top three highest paying symbols show up anywhere on screen, you get a multiplier of 4x, 5x or 6x your total bet.This isn't huge, but it certainly helps top up your wallet every now and then when those 5 of a kind wins are few and far between.
Scatters and Free Spins: 3, 4 or 5 free spins trigger 7, 10 or 12 free spins respectively.
You can re-trigger these spins indefinitely, but to be honest, you'll be lucky to get those coveted 7.
We say coveted because during any spin wilds can be added on screen, and stay there, till the end of the free spin round – like in the Cazino Zeppelin mobile slot for example.
Vault Trail Bonus: 2 Vault Bonus symbols anywhere on screen trigger the Vault trail bonus.
Each reel contains progressively bigger prizes, but if at any point a symbol turns red, don't worry: you can re-buy a spin on that reel, if you have enough prize money banked.
You'll then be shown to a second screen where you'll see a gizmo, with reels, called a cryptex (not a Codex, funnily enough).
Your mission is to spin each reel, and get the right symbols. You'll know because those symbols turn green, you'll get cash, and move on to the next reel.
Of course, you might not want to gamble away your winnings, so thats a choice you'll have to make. Personally, we think it's worth trying to get to at least reel 4 for any decent prizes, but we like to take risky bets.
We were pleasantly surprised by this Codex online slot. We weren't expecting much from SpielDev, but found ourselves enjoying a fun 20 payline game with several bonus feature.
Could the free spins have come a little more often? Sure. But when have we not said that?
Ultimately, this is a medium variance game, with decent returns, and graphics that pop online, even if not shine on mobile.
Or you can play Codex at one of these mobile casinos:
