Theme – Audio and Design Features – elegant art nouveau style visuals


There’s a rather unusual look to the Codex of Fortune slot. There aren’t too many games that take inspiration from French Art Nouveau. Rather lovely it all is too. The game is the sequel to the Turn Your Fortune slot released in January 2019. All in all, the design here is very easy on the eye.

On the deep blue reels, you’ll find stylised A to J royals alongside 5 more rewarding animal-inspired jewels that have been crafted in Art Nouveau style. The best paying symbol is the red lion which pays 5 x your total stake if you land 5 across a payline.

There’s also a jewel-encrusted key which is the wild symbol. This can appear anywhere on the reels and substitutes for all symbols bar the scatter, key and +10 symbols.

The peacock jewel is the game’s scatter symbols. Land 2 of these alongside a standard winner to trigger the re-spins or 3 of them for a free spins trigger. To the left of the reels is the Codex Meter which becomes active during the re-spins and free spins features to award extra prizes.

Codex of Fortune has been created using HTML5 technology and is fully optimised for play on all devices including mobiles and tablets as well as desktop computers.

Codex of Fortune Bonus Features

It’s not just the theme and design that’s are a little unusual in Codex of Fortune. The gameplay is too. With 4 bonus features, central to the action are the Fortune Wins where collecting special symbols awards cash prizes. Advance through the levels and the value of prizes rises too, up to a maximum of 10,000 x stake.

Fortune Wins feature

The Fortune Wins feature is a special bonus game that becomes active during the re-spins and free spins. Collect special symbols during these rounds to win bonus prizes. You can see the value of the potential awards in the meter to the side of the reels. Each of the 7 levels is made up of 5 steps.

Hope to see key symbols appear as this will take you up a level and the prizes for collecting symbols increase. There are 7 levels to work your way through in all. At Level 7, the prizes can reach a mammoth 10,000 x your total stake. Here are all the payouts available:


Fortune Re-Spins feature


The Fortune Re-Spins feature is triggered by landing 2 scatters alongside a standard winning combination on the same spin. The standard symbol from the triggering spin will be the collection symbol. A re-spin then follows on reels which are made up only of blanks, the collectable symbol and a key symbol.

If a collectable symbol lands, it’s added to the meter and another re-spin follows. Land a key and you’ll unlock the next level with potentially bigger rewards up for grabs. The re-spins continue until there’s one where no new collectable or key symbol lands. You’ll then have an opportunity to Save the Keys.

Save the Keys feature

You can use the keys won and collect your prize. Alternatively, you can reset the Meter to Level 1 but save the keys and use them when you trigger the Free Spins feature. Known as the Save the Keys feature, you can then use up to 3 keys to advance up the levels with a free spins trigger.

Free Spins feature


To trigger the Free Spins feature, you need to land 3 scatter symbols anywhere on the reels on the same spin. A 3-tier mini wheel then spins. This determines how many free spins you’ll receive (between 7 and 13), what will be the collectable symbols and how many extra keys and potential level ups are awarded.

All the collectable symbols that land during the free spins are collected in the meter. Look out for the +10 symbol which fills the meter with 10 symbols. Fill a meter with 20 symbols to advance to the next level. Look out for +1 symbols too. These add an extra free spin to your total when they land.

Codex of Fortune Review Summary – stylish design + unusual gameplay combine nicely

The Codex of Fortune slot offers something unusual both in the way it looks and plays. The Art Nouveau visuals are stylishly done. The gameplay delivers something fresh too courtesy of the symbol collect element that’s key to both the free spins and the re-spins.

Whether or not to carry over keys adds a level of interactivity too. If you save the keys, you could benefit from much bigger wins. Getting to the higher levels can deliver payouts of 10,000 x stake if you reach the top step in Level 7. The bigger payouts should come in the free spins but it will take approximately 368 spins to trigger them.

If you fancy trying something that’s a little unusual, try and unlock the Codex of Fortune. Personally, it’s an acquired taste (like the theme) so would rather play some of NetEnt’s other popular titles.

My favourite is Dead or Alive 2 which high a Wild West theme, has 3 free spins features and offers wins up to 111,111 x your total stake. Another option is Rome: The Golden Age which comes with multipliers up to 2,000x in the free spins and max wins of 100,000 x your total stake.
