Codex Slot from Red Tiger Gaming takes you into a world full of hidden secrets and treasures which could all be yours if you’re able to break the code. This slot allows you to test your code-breaking skills on a 5-reel, 3-row setup with 20 Paylines for landing wins.

Overlapping cog wheels serve as the game’s background with symbols of invention icons and playing cards gracing the reels. The design isn’t the most stunning out there but it does fit the theme perfectly. If you’re up for a challenge, Codex offers three of them with exciting rewards up for grab. At its best, this slot pays 1,000x the stake per spin


How to play

Bet levels start from 0.20 up to 7 coins per spin. To trigger a win, you would require a 3 of a kind combo of the same symbol type.

Occupying the reels are symbols of different coloured invention icons and playing cards.

The red inventions symbol is the most rewarding offering 1,000x the stake for 5 on the reels.

Codex Slot Special Features

Special symbols

The wild symbol substitutes for the regular game symbols except the vault bonus, free spins, or invention combo symbols.

Bonus features

Vault Trail Bonus

The vault trial bonus will unlock the cryptex reels where you can spin to win up to 195x the stake. This feature is triggered when vault symbols land on reels 2 and 4. It will activate the 5-reel cryptex which holds a prize.

Players would need to get the correct combination by spinning each reel one at a time. If you’re unable to unlock the first reel, the feature ends and you will be offered 5x your stake. If you’re unable to unlock reels 2, 3, or 4, you can buy a re-spin with your bonus wins.

Invention Combo Feature

On the reels, you will find three invention symbols which will add multipliers of 4x, 5x or 6x to any win when you land a combo of three on the reels. This feature is also active in the free spins bonus round.

Free Spins

You will have to collect at least three bonus symbols on the reels to trigger the free spins feature. This will award 7, 10, and 12 free spins for 3, 4 and 5 scatter symbols. During the free spin feature, any wild symbols landed will randomly turn into sticky wilds.

More sticky wilds can be added at random, covering the entire grid. The free spins feature can be triggered indefinitely by landing more scatters during the bonus round.

Codex Slot Jackpot

At its best, this slot would pay out 1,000x the stake per spin. However, it doesn’t offer a jackpot prize.

Return to Player (RTP)

Codex Slot has an RTP of 95.01%.


With high volatility, hitting wins on this slot would be tricky to nail. Still, it offers just the right incentive to attract any punters to its reels. You can land wins of up to 1,000x the stake on the reels with a little bit of help from the invention combo multipliers and the free spins feature.
