How Codex of Fortune works

NetEnt's famous slot machine, Turn your Fortune, is back with an improved version called Codex of Fortune! So sit back and hold on to your keys as you try to reach the top of the closed codex and win the jackpot!

Codex of Fortune is a slot machine developed by online game provider NetEnt. It has been available at most online casinos since 30 June 2021. Its payout ratio (RTP) varies depending on the strategy adopted by the player between 90% and 98% with an average of 96%. The volatility of this slot is very high and its winning potential is much more impressive than the previous version, with the possibility of winning up to 10,000 times the starting stake. The starting grid is rather classic with 5 reels consisting of 4 symbols each. The main tool of this slot is on the left. It is a large wheel, called a codex, with multipliers placed on it, which will influence the respin as well as the bonus. In addition to the wild that substitutes for all other symbols to make connections easier and the free spins bonus, a Hold & Respin feature is available in Codex of Fortune. To trigger this feature, you will need to get 2 Scatters on a game round where a valid connection is made.

The symbol used in this paid connection will then be the sticky symbol of the respin: all other symbols disappear from the grid and a respin is awarded each time this sticky symbol appears at least once. It is collected each time in a counter on the left and when this counter is full (5 symbols), you climb one floor on the codex on the left side of the grid. Getting a key from a respin keeps the feature alive and spins the codex to reach the next level of the wheel. There are, in total, 7 levels and each level has higher multipliers than the previous one. When no sticky symbols or keys appear, the respins stop. Your floor on the codex then defines your bet multiplier and therefore your winnings. If one or more keys have been collected during the respin, you have the option to keep them aside by dropping back to level 1 of the codex. We will see later why this technique gives the highest RTP.

Codex of Fortune Symbols

In addition to the Wild, Keys and Scatter, there are 9 symbols in Codex of Fortune. They are divided into two categories:

• The medium value symbols are represented by various golden animals and a shell. These are the symbols that pay the most, but cannot be called premium;

• Low value symbols, otherwise known as common symbols, are represented by the high values of a deck. They appear more often, but pay much less.

Above are the potential payouts for a €1 bet.

The different connections in Codex of Fortune

There are many different connections available in Codex of Fortune. Whether it's keys, lines or diagonals, there are many ways to make paying connections. In fact, there are 40 predefined paylines. In order to get a valid connection, at least 3 identical symbols must be present on a line and connections are made from left to right. The infographic below shows you the 40 connection lines in Codex of Fortune.

How the Codex of Fortune bonus works

Getting 3 Scatter symbols on a single pay spin triggers the Codex of Fortune bonus. These bonus symbols can only appear on reels 1, 3 and 5. A wheel is then spun to decide your fate: between 7 and 13 free spins can be awarded and it will be possible to retrigger by getting Scatter symbols again during the free spins. This wheel also decides which symbol will be collected during the bonus round and you may also be awarded one or more keys. You will then have the choice of whether or not to use the keys that you have collected in the various hold & spin games beforehand. By using the keys, you increase the level of the codex to obtain a higher maximum winning potential. Simple connections can pay off in the bonus round, but the main objective to really get close to the potential of this slot is to climb as high as possible on the codex. You need to collect the selected symbol 20 times to fill the meter and climb the codex one floor. Reach the last floor of the 7th level of the codex to get the jackpot of 10,000 times the starting bet! In the image below you will find all the multipliers for each different level of the codex wheel.
