How to play Codex of Fortune mobile slot

Turn the codex and see if you can win as much as 10,000x your bet thanks to some handy keys and plenty of respins in this Codex of Fortune slot.

Codex of Fortune is a 5 reel 40 payline slot machine steeped in luxury, where 2 scatters and a win will trigger a re-spin where you collect symbols to get instant cash wins.

3 scatter will trigger the free spins, giving you a higher chance to turn the key on the codex and win that top win. But you have to collect keys to turn that codex.

Sounds complicated? It is a little bit. Especially if you don’t use the right slot strategies, the RTP of this Codex of Fortune slot can go as low as 90%. But if you use the right strategy, it can go up all the way to 98%, better than most mobile slots out there.

How the Codex works:

On 2 scatters and a win, you’ll get a respin of the reels to collect more of that symbol. The more you collect, the bigger your win, but also the bigger your instant win on the left. So far, so much like the original Turn Your Fortune slot.

But you only have 1 respin to try and collect as many symbols as you can and go up that Codex. At most you are looking at winning 150x your bet.

Unless you get a key, and turn the Codex to the next level, giving you a higher instant cash win amount. But here’s the thing – you absolutely should NOT do that.

What’s the best Key strategy for the Codex of Fortune slot?

The optimal Codex of Fortune mobile slot strategy is to save the keys won in fortune re-spins and to use them in free spins when you have 3 or more keys saved.

Obviously, if you are about to run out of budget use them on the single re-spin if you need to. But if you can wait for those 3 scatters, you’ll get 7 to 15 free spins to try and collect super symbols and super wins.

Because at the start of the Codex of Fortune free spins you can choose to use your saved keys to automatically increase the win by up to 3 levels – a top win of 400x your bet.

If you manage to get all the way to level 7 that’s where you’ll win 10,000x your bet plus any wins from the free spins. The most we’ve won is 1,000x our bet, but we can promise you we didn’t care. We loved it.

This Codex of Fortune NetEnt slot isn’t for everyone, but if you enjoy a challenge and having to think a little more than just spin and win this game is for you. If not, maybe go read the CashOMatic slot review instead.

In-game bonus features

Wild: This butterfly symbol can appear anywhere and substitutes for all symbols except for scatter symbols, key symbols, and +10 symbols. The wild symbols are not collected to full the fortune wins.

Fortune Re-spins: 2 scatters on the reel in combination with a bet line win triggers this respin. Collectible symbols are then sticky on the screen, and more could be collected to fill the fortune wins meter. Each time the meter is full it moves the codex upwards for instant wins.

There are 7 levels, but the level you are likely to play on the most in the base game:

  • Step 1: 5x your bet
  • Step 2: 10x your bet
  • Step 3: 20x your bet
  • Step 4: 50x your bet
  • Step 5: 150x your bet

To move up the levels you need to collect keys, which you can then use to turn the codex and go up higher levels during the respins. How much you win per level depends on:

  • Level 1: 150x your bet
  • Level 2: 200x your bet
  • Level 3: 400x your bet
  • Level 5: 2,000x your bet
  • Level 6: 5,000x your bet
  • Level 7: 10,000x your bet

The respins end when no more of the collectible symbols show up.

Free Spins: 3 scatter symbols with or without a bet line win triggers the free spins. If you have any save keys you can use them now to increase your

Save the Key Feature: At the of a Fortune Re-spin, if you've won any keys, you'll be offered a choice to save the keys. If you choose not the save the keys, you switch levels and win an instant win there and then. If you choose to save the keys, the fortune wins level is reset to level 1. You can use up to 3 saved keys to level up the fortune win.

You'll then spin a fortune wheel to determine how many free spins your win, 7 to 13. One collectible symbol will now be chosen in the free spins and it's always a medium or low win symbol.

The special +10 collectible symbol landing anywhere on reel 2 fills the meter by 10, but each time the meter is filled by 10 spaces, you move one step up the Fortune win. A key on reel 5 will instantly level up the Fortune Wins.

At the end of the free spins, the total win of the bonus round and the Fortune win are added together to give you your total win.

Codex of Fortune Review Conclusion

There's something remarkably fun about this Codex of Fortune slot on mobile though we suspect this game won't be for everyone.

Mostly because it's incredibly frustrating to have to find those scatters, wins, and keys, and you feel like you are trying to actually break a code.

Some people will enjoy that challenge, others will want to play on something a little easier like the Free Reelin Joker slot instead.

But if you are up for a challenge and love a high-limit slots with big wins, this addition to the NetEnt mobile slots selection is just what you need.
