Space Communication
Space Communication is a feature that is accessible from the game settings.
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, Bacteria, and Gene Strands.
The amount of Diamonds received depend only on the secret code, but the amount of Gene Strands depends on how many are currently owned, whereas the Bacteria reward depends on the current BPS.
On average, the Space Communication rewards are about three times more valuable than the Red Bacteria rewards of the same type.
