99 Nights in the Forest is a Roblox survival game where you build a camp, search for missing children, and try to survive each night. If you want more Diamonds for classes, codes can give you a quick boost. As of September 2026, recent gaming guides report three standard 99 Nights in the Forest codes and one special fishing reward. The codes below have not been tested in-game for this article, so their availability may change.
99 Nights in the Forest Codes
| Code | Reported reward | Where to enter it |
|---|---|---|
awardwinner_yay | 15 Diamonds and 3 random Flames | Lobby Codes menu |
forestwakesup26 | 15 Diamonds and 3 random Flames | Lobby Codes menu |
afterparty | 15 Diamonds | Lobby Codes menu |
yay fishing | 2 Diamonds | In-game chat while fishing |
The first three codes are reported to give 45 Diamonds in total. yay fishing is different: it does not work in the Codes menu, and its reward can reportedly be claimed only once per account.
How to Redeem Codes
You can redeem the three standard codes before starting a survival run:
- Open 99 Nights in the Forest on Roblox.
- Select the Diamond icon in the lobby.
- Open the Codes menu.
- Enter one code from the table.
- Press Submit and check your reward.
Enter each code separately. If one fails, check that you copied it without an extra space.
How to Claim the yay fishing Reward
To try the fishing reward, start a run, get a fishing rod, and begin fishing. While your character is fishing, open the in-game chat and type yay fishing. Do not enter the phrase in the lobby’s code box.
The reported reward is two Diamonds. If you have already claimed it on your account, repeating the phrase should not give you another reward.
Expired Code
happyhalloween is reported as expired. It previously rewarded 10 Candy, but players should not expect it to work now.
Why Isn’t a Code Working?
Make sure you are playing the original 99 Nights in the Forest experience by Grandma’s Favourite Games, not a similarly named Roblox game. Then check that you are using the right redemption method: standard codes go in the lobby, while yay fishing goes in chat during fishing.
A code may also fail because you have used it before or because it expired after this article was updated. Since the listed codes have not been independently tested for this article, an in-game rejection should take priority over their reported status.
