Space Communication is a feature that is accessible from the game settings. It becomes available from Planet 5.

By sending a secret code from the Space Communication menu, it is possible to get some free resources, such as Diamonds, Bacteria, and Gene Strands.

Each code can only be used once and, after sending a correct code, there's a 12 hour cooldown before another code can be entered. Correct letter capitalization does not affect whether it will be accepted.

Sometimes codes have an expiration date, after which they are no longer usable. Exceptionally rewarding and difficult codes can also have a limit of uses. This means that each player can still enter the code only once, but the total number of players that can receive the reward is limited.

Finding Secret Codes

The codes are published on different webpages and social media profiles of the game. Some codes are hidden or unrevealed.

The sites with secret codes include:

Rewards

There are three reward types:

Diamonds - the amount received depend only on the secret code
Bacteria - reward depends on currently owned Bacteria amount
Gene Strands- reward depends on currently owned Gene Strand amount. This is not affected by more Gene Strands bonus from Evolved Bacteria.
