June 18, 2026: I've added the latest 99 Nights in the Forest code to our list, celebrating the most recent update and granting some exciting rewards.
99 Nights in the Forest codes are helpful things to have in this spooky adventure, as they can boost your chances of survival in the eerie woods while searching for lost children. Whether you go in solo or team up with other players, you'll need to craft items and build a camp for protection against the strange creatures, cultists, and other threats that lurk in the darkness.
The promos available give you some free Diamonds, and this Gem currency lets you unlock new 99 Nights in the Forest classes with different perks to help you live through the night in this Roblox experience. For all of the details, here are the current codes for 99 Nights in the Forest, along with an explanation of how to redeem them within the game.
If you're looking for more rewards, then we've got the lowdown on how to earn free diamonds in 99 Nights in the Forest via our separate guide.
All 99 Nights in the Forest codes
Here are the latest 99 Nights in the Forest codes to redeem for free Diamonds:
- FORESTWAKESUP26 – 15 Diamonds, 3 random Flames new!
- AFTERPARTY – 15 Diamonds
- yay fishing – 2 Diamonds (see separate instructions below)
Now that codes for 99 Nights in the Forest have been around for a while, we've got a better idea of how often fresh promos will be released and how long they will remain valid for. New codes drop very infrequently, with only one so far relating to the Halloween event that has now expired, while the original codes still remain valid. These promos are not case-sensitive and there are no account prerequisites you need to reach first, so you can use them as soon as you start playing. Below you'll find instructions for redeeming 99 Nights in the Forest codes, to get you on your way.
How to redeem 99 Nights in the Forest codes
To redeem 99 Nights in the Forest codes, all you need to do is join the experience via Roblox and arrive in the main lobby. Once there, hit the Diamond icon in the bottom left corner of the screen, then the Codes button that appears next to the Diamond purchase options. This will bring up an ENTER CODE text box, then type a code from our list and hit SUBMIT to claim it. Codes for 99 Nights in the Forest are not case-sensitive, and there is no minimum level or other requirements so you can use them right away.
How to redeem the yay fishing code
Redeeming the yay fishing 99 Nights in the Forest code requires a different approach, as you can't claim it through the usual process laid out above. Instead, start a solo or multiplayer game and then upgrade your campfire to Level 2 – this means levelling it up twice. Doing that will expand the area you can explore, so look around until you find the Fishing Shack pictured above.
Go inside the shack and take an Old Rod, then stand next to a fishing hole and equip the rod. While you're fishing, open the game chat and type yay fishing then hit enter to post it. If this code has worked, then two Diamonds will appear next to you ready to be collected – they may have fallen into the fishing hole, so look there if you can't see them. This process can only be done once, so don't expect more Gems every time you go fishing.
Expired 99 Nights in the Forest codes
HAPPYHALLOWEEN– 10 Candy
We now have the first of the 99 Nights in the Forest codes to expire, as this promo is no longer valid since the Halloween event concluded. We don't expect to see many more codes here for a while, but as always you should make sure you claim any that are available as soon as you can.
