Codes checked: 18 September 2026 · Game last updated by the developer: 7 September 2026
99 Nights in the Forest is a co-op survival game on Roblox where a group tries to last the night against whatever is moving in the trees. Codes pay out Diamonds, the currency used to unlock new classes, and occasionally Flames on top.
New codes tend to arrive with major updates or after a bug that cost players progress, rather than on a weekly schedule. That means the working list stays short and stable for stretches at a time. Every code below was live when this page was last checked, and anything that has stopped working is listed underneath instead of quietly deleted. More lists are collected on our Roblox codes page.
All Working 99 Nights in the Forest Codes
- FORESTWAKESUP26: 15 Diamonds and 3 random Flames
- AFTERPARTY: 15 Diamonds
Type codes exactly as written. The redemption box is fussy about stray spaces, and pasting is safer than typing. There is also a separate chat reward covered further down, which is not entered in the codes box.

What Diamonds and Flames Get You
Codes here pay in two things. FORESTWAKESUP26 gives 15 Diamonds and three random Flames, and AFTERPARTY gives 15 Diamonds. Diamonds are the premium currency, so a code is a small top up rather than a shortcut past the grind.
The Flames are the part worth redeeming for. They arrive at random, which means the same code can be worth very different amounts to two players.
How to Redeem Codes in 99 Nights in the Forest
- Launch 99 Nights in the Forest on Roblox and load into a run.
- Select the Gems icon in the bottom left corner of the screen.
- Choose the Codes button along the bottom of the panel that opens.
- Enter one code and submit it.
- The Diamonds are added immediately. Repeat for each remaining code.
How the yay fishing Code Works
This one is not entered in the codes box at all. Type yay fishing into the in-game chat while you are actually fishing, holding the rod and inside the fishing minigame during a live run rather than sitting in the lobby. It pays out 2 Diamonds and works once per account, so there is no point repeating it.
Where New 99 Nights in the Forest Codes Come From
Codes come from Grandma’s Favourite Games, the group that publishes the game. Codes are announced by the developers themselves, usually in the game’s official Discord server and on the Roblox experience page during update notes. Following those directly is the fastest route. Every list online, including this one, is downstream of those same announcements, which is why the working codes match across sites.
Why Your 99 Nights in the Forest Codes Are Not Working
- The code has expired. Short campaign codes are often pulled within days.
- It was already claimed on that account. Each code works once per player.
- A character was mistyped, or a trailing space was copied in with it.
- You are in the lobby rather than an active run, which matters for the fishing chat reward.
Frequently Asked Questions
Do 99 Nights in the Forest codes expire?
Most do. The two above are current, and the ones in the expired line stopped working when their event ended. Redeem a new code the day you see it rather than saving it.
Are the codes case sensitive?
Yes. Type them exactly as written, including capitals, and avoid pasting a trailing space.
How often do new codes arrive?
They come with updates and milestones rather than on a schedule, which is why this page carries the date it was last checked.
