Codex of Fortune Review

Instead of coming up with something brand new, NetEnt has decided to build on a rather mediocre release from their back catalog, namely Turn Your Fortune. Codex of Fortune comes with a similar Art Nouveau visual style, and the features are also very similar. The biggest difference is found in the math model, as you can now look forward to possible payouts up to 10,000x your stake, instead of the forgettable 2,000x potential on offer in the original.

Another interesting difference is the ability to “save keys”, and thus sacrifice Hold & Respin payouts to get a head start in the bonus round (where much bigger prizes can be landed). How you play this will determine your RTP quite drastically - between 90.2 % and 98 % - but returns will hover around 96 % for average play. As in the original, it’s really all about collecting symbols to climb the 5-tier prize ladder, and collecting keys to upgrade the prize ranges.

Codex of Fortune slot Features

The butterfly wild steps in for all regular pay symbols, like wilds usually do, and this helps you form winning combos. The Fortune Wins feature is tied to the massive 5-tier device you see on the left-hand side. It contains 5 prize tiers across 7 upgradable levels, and it comes into play both during the Hold & Respins feature and the Bonus Round.

The Fortune Respins feature is triggered when you land 2 scatters anywhere, as well as a regular win, on the same spin. The symbol from the regular win becomes the ‘collectable symbol’. Only blanks, more collectable symbols and a special key symbol lands during the respins feature, and you can win up to 200x your stake at the most.

If you land at least one instance of the collectable symbol, and/or a key symbol, you will be granted another respin. All collectable symbols are sticky on the reels, and the feature ends if you land a respin with only blanks. The collectable symbol is collected in a small meter, and you move 1 tier up the Fortune Wins prize ladder per meter you fill.

The key symbol turns the 5 prize tier cylinders one position clockwise, and this upgrades all 5 Fortune Win prizes to a higher level. When the respins feature is over, you enter the Save the Keys feature. You can either use the keys you’ve collected to get your Fortune Prize Win, or you can save the keys for the Bonus Round. The highest RTP strategy is to always save your keys.

You need to land 3 scatters on reels 1, 3 and 5 to trigger said Bonus Round, and a bonus wheel will then award between 7 and 13 free spins. The wheel also selects a collectable symbol for you, and hands out a key symbol if you’re lucky. You can then use up to 3 saved keys to start higher on the Fortune Prize ladder.

All collectable symbols you land fill the Fortune Win meter, and you need to collect 20 symbols to level-up 1 tier. Special +10 symbols count as 10 collected symbols however, and there is also a +1 extra free spins symbol to look out for. Keys turn the 5 cylinders to reveal upgraded prizes as usual, and 10,000x your stake is the level 7 top prize.

This is definitely one of those games that sound way more complicated than it actually is when you read about them. In that regard, watching the brief and edited highlights video from our 200 spins test session might help make things a lot clearer for you.

Review Summary

If the above feature description had you scratching your head for a bit, please allow us to clarify in a brief summary. The game is quite simply about triggering respins or free spins, in which you’ll collect symbols and keys to climb and upgrade the Fortune Win prize ladder. The respins feature is mostly there to keep you afloat, while far more significant payouts can be landed from the bonus round.

The RTP varies a lot depending on your “strategy”, and theoretical returns can go as low as 90.2 %, or as high as 98 %. It’s always best to save your keys for the bonus round if you want the highest possible returns in the long run. However, giving up “smaller” respin wins means you’ll need a bigger bankroll to stay afloat. This can be a fine line to balance, and it certainly complicates things for players who just want to spin the reels and don’t think too much.


  • Hold & Respins w/ prize upgrades
  • Bonus round w/ bigger prize upgrades
  • Save the keys strategy affects RTP
  • Win up to 10,000x your stake


  • Might be too convoluted for some players

If you enjoy Codex of Fortune slot you should also try:

Turn Your Fortune - is the predecessor release from NetEnt, and it comes with a very similar cylinder prize upgrade feature. The big difference is that you cannot save keys to affect the RTP here, and the highest possible prize is “only” 2,000x your stake.

Coils of Cash - is a literal powerhouse of a game from Play’n Go, and it plays out on 6 reels, 1 top reel and 2,304 ways to win. The power coil horizontal reel builds multipliers up to 625x via cascading wins, and you can win up to 30,000x your stake in the bonus round.

Victorious MAX - is another release in NetEnt’s Max series, and it comes with a staggering 30,000x your stake potential. The bonus round boosts all wins with a 6x multiplier, and the RTP is a very decent 96.88 %. The base game might be a bit of a grind, but hardcore gamblers might wanna give this one a whirl.

How does the Fortune Win Respins feature work?
