Grow Crystals is a slow-burn idle game about doing exactly what the title says. You plant crystals, watch them grow and multiply in value, then sell them on to afford rarer, faster-growing varieties. The best part is that your garden keeps working while you are away — offline progress means you come back to a small fortune waiting to be harvested.
Progress runs on Coins, and Coins are what the codes give you. There is only one live code at the moment, but 150 Coins is a meaningful jump early on, when the good crystals still feel out of reach.
All New Grow Crystals Codes
- 100k: 150 Coins
One code is not much of a list, we know — but it is the only one currently confirmed working by multiple trackers, and we would rather give you one code that definitely redeems than pad this section with guesses.
Expired Grow Crystals Codes
This one used to work but has been switched off:
- B1gUpd8
How to Redeem Grow Crystals Codes
- Launch Grow Crystals on Roblox.
- Click the Twitter bird icon in the top-right corner of the screen.
- Type a code into the Enter Code Here box.
- Press Redeem and the Coins are yours.
How to Get More Grow Crystals Codes
New codes for this game are rare and usually celebrate milestones — the live code marks the 100k milestone, which tells you how the developers think. They announce codes in the game’s Discord server and through the Fun Growing Games Roblox community, so those are the two places worth an occasional look.
Because codes arrive so rarely here, it genuinely pays to keep this page saved: we check it regularly and will post the next milestone code as soon as it is confirmed working.
Why Are My Grow Crystals Codes Not Working?
Double-Check for Typos: The active code is 100k, all lower case after the numbers. Typing 100K with a capital K will not work — these codes are case-sensitive, so copy the exact spelling.
The Code Has Expired: Grow Crystals codes do get retired. B1gUpd8 worked for a long time before it was switched off, so if a code you found on an older page fails, that is almost certainly what happened to it.
The Bird Icon Is Easy to Miss: Code entry in this game hides behind the little Twitter bird icon in the top-right corner. There is no code box inside the shop or the settings menu, so if you have been hunting through those, open the bird icon instead and the Enter Code Here field will be waiting.

Conclusion
Short and sweet: redeem 100k for 150 Coins, skip the expired B1gUpd8, and let your crystals do the rest of the work while you are offline. We will update this page the moment the next milestone code shows up.
