Codex of Fortune: Slot Overview

Anyone with a soft spot for spinning cylinders will be pleased to hear that NetEnt has revisited an older title, Turn Your Fortune, and refreshed it. Calling it a huge revamp might be a stretch, because much of the time it’s difficult to spot meaningful differences between Codex of Fortune and the original. Still, some adjustments to the math model, the addition of one more feature, and a more generous max win have helped lift what was an average slot into something that could better suit more discerning players.

Codex of Fortune runs on a grid of 5 reels, 4 rows, and 40 fixed paylines. On the visual side, it’s only a modest step up from Turn Your Fortune; the artwork looks a touch sharper, but the most obvious change is simply the backdrop colour. Where Turn Your Fortune leaned into burgundy tones, Codex of Fortune opts for a midnight blue setting. Overall, the style remains largely unchanged, keeping the same French Art Nouveau vibe, visible in the typography and reflected in the symbol design.

Even if the presentation is largely familiar, the mechanics have seen more meaningful changes. NetEnt has swapped out the medium volatility for something punchier, and several key stats have been pushed upward as a result. The standout is the potential, though the RTP is also notable. Because one feature includes a small strategic element, the return can vary. Choosing the average strategy produces an RTP value of 96%, while adjusting your decisions can shift the return anywhere from 90.2% up to 98%.

With stakes ranging from 20 p/c to $/€100 per spin, standard wins arrive at about 1 in 4 spins (25.4%), paid when three or more matching symbols connect across a payline. The symbol set is unchanged: J-A royals make up the lower values, followed by shells, fish, turtles, owls, and lions for the higher-paying icons. Hit a five of a kind with premium symbols and you’ll trigger coins worth 3 to 10 times your stake. Any symbol can appear stacked on the reels, so full-grid wins are possible. The Faberge-style butterfly symbol acts as the wild, landing on any reel to replace regular pay symbols and help form winning combinations.

Codex of Fortune: Slot Features

At this point, Codex of Fortune begins to separate itself from the earlier game by introducing the new Save the Keys feature alongside Fortune Wins, Fortune Respins, and free spins. Fortune Wins refers to the mechanism positioned to the left of the reels. It has 5 horizontal levels, each split into 5 segments, with values increasing as you climb. During Respins, Fortune Wins prizes cap at 200x the bet, while in free spins they rise dramatically to 10,000x the bet.

Fortune Respins activate when 2 scatter symbols appear on the reels. When the respin starts, all non-winning symbols are removed from the grid, while one winning combination is locked in place and becomes the collectable symbol. Respins can land only blanks, symbols, or keys. If additional collectable symbols land, they’re gathered and another respin is granted. Every 5 collected symbols advances the cylinder up by one horizontal level. When keys land, they shift the cylinder one position horizontally. Respins finish when no new symbols appear or once 20 have been collected.

After respins end, the Save the Keys feature kicks in. You can either spend keys to claim a prize from Fortune Wins or hold onto them to enhance prize values during free spins. The maximum RTP comes from saving keys whenever you can.

To trigger free spins, scatters must land on reels 1, 3, and 5. Before the bonus begins, a bonus reel spins to award 7-13 free spins, select a special collectable symbol, and potentially add a key symbol too. Any keys you’ve saved can be used to begin higher on the Fortune Wins. In addition, during free spins, all collectable symbols that land are added to the Fortune Wins meter. Each time the meter is filled with 20 spaces, players move one level up. Keys continue to move the device horizontally as they do elsewhere. Fortune Wins prizes are totalled once the round ends.

Codex of Fortune: Slot Verdict

It may read a little complicated, but once you’re playing it’s quite easy to follow. In short, Codex of Fortune revolves around landing scatters to start respins or free spins, then building up keys and collectable symbols to boost the rewards from the Fortune Wins device. If you’ve tried Turn Your Fortune, the core loop will feel very familiar. The key change is the Save the Keys decision: do you take an immediate payout, or stash keys for a shot at bigger outcomes in free spins? The safer option is tempting, but free spins can deliver much larger prizes, and keeping keys also improves the theoretical return.

One major point of separation is the potential. Turn Your Fortune topped out at 2,000x the bet—respectable, but hardly a headline-maker. Codex of Fortune increases that ceiling to 10,000 times the stake, which is far more likely to grab attention.

Ultimately, Codex of Fortune is clearly a stronger lure for players who weren’t impressed by Turn Your Fortune. That said, beyond the significantly higher max win, much of the experience remains familiar. So if the visuals already felt underwhelming two years ago, or the low-count paylines format isn’t your thing, even 10,000x may not be enough to convince you to give it a go.
