Codex - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction

Code-breaking has fascinated some of the greatest minds in history. Codex plays into our fascination with hidden secrets and treasures with some exciting and compelling features in this stunning 5x3, 20-payline history themed online slots.

Played out against a background of steampunk-inspired cog wheels, Codex offers players three challenges and rewards that offer some dramatic potential for big wins.

First there’s the invention combo activated by three special symbols that adds random multiplier prizes.

Land the free spins with sticky wilds, and you might just retrigger them indefinitely.

Unlock the vault trail bonus to play across multiple levels and crack the secret combination. Get it right to win a massive multiplier prize.

This slot also comes in a version with a randomly generated progressive jackpot and is available in portrait and landscape mode on your mobile and tablet. You can assess the gameplay risk-free by playing Vibra Gaming online slots at Slots Temple.

Theme, Graphics & Soundtrack

Probably the most famous codex in the world, there really is a Da Vinci Code and Bill Gates paid over $30m to own it. Codex actually means book, and the code wheel familiar from the movie is properly known as a cryptex - that’s the basis for the design of this exceptional slot.

Each segment of each reel spins independently on its axis, creating a startling visual effect if you’re only used to standard reels. The pictograms are perhaps the only letdown as there are plenty of fairly standard royals alongside the special symbols and invention icons in this 12-symbol game.

But it’s the background, animations and effects that really catch the eye. The screen is filled with whirring gears and whenever a feature triggers, the reels are replaced mechanically by another set. The detailing is fabulous.

The ethereal soundtrack adds another mysterious and atmospheric layer to this hugely compelling game.

RTP & Volatility

High-volatility gameplay and 96.14% RTP combine with a 24.47% hit rate to create a game that most players will be keen to play.

How to play Codex

Vibra Games have iterations of this game for desktop, mobile and land-based play. We played the desktop version and found the player interface a little complex compared to other games. Our step-by-step guide will help you get ready to play.

- i opens up the paytable with game information

Bet Sizes & Paytable Wins

There’s quite a tight range of bets available in Codex of between 0.40 and 20.00 coins per spin. While that should suit most players, risk-takers might like more action.

Land five matching symbols across one of the 20 paylines to earn the biggest payouts in this slot. These wins are calculated as multipliers of your stake as follows:

- Red invention symbol pays 1000x
- Blue invention symbol pays 750x
- Green invention symbol pays 500x
- A pays 100x
- K & Q pay 80x
- J & 10 pay 60x

This slot has high potential for wins of 1000x your stake and more, but beware of the high volatility that makes them tricky to nail.

Max-win 3,000x

Bonus Features

It’s fair to say that Codex is packed with some intriguing and innovative features that you may not have come across before. There’s an excellent balance between the different triggering symbols, with the bonus and free spins vying to be the most powerful feature.

Invention Combo Feature

The three invention symbols can add a multiplier prize of 4x, 5x or 6x to any payline win when all three symbols land on the reels. This feature is also active in the free spins round.

Free Spins Feature

Look out for the Free Spins symbol that can land on any reel:

- 3 symbols triggers 7 free spins
- 4 symbols triggers 10 free spins
- 5 symbols triggers 12 free spins

Free games feature sticky wilds and indefinite retriggers with the potential to cover the reels in wilds during your spins for huge potential.

Vault Trail Bonus feature

Players have one spin to unlock the first reel and then one free spin for every successful unlocked reel. Match the entire five-symbol combination to win 195x your stake.

Overall Review: Our Verdict

There are some high-quality code-cracking games around, like the Da Vinci Codex online slot from GameArt. But Codex is such a well-realised combination of gameplay, maths, audio-visuals and features that you’ll want to play again and again.
