Where to enter codes
- Launch 99 Nights in the Forest and stay in the lobby. The Codes menu isn't available once a run has started.
- Tap the Diamond button in the bottom-left corner of the screen.
- Open Codes in the bottom-right corner of the window that appears.
- Paste the code into the Enter Code box exactly as written.
- Press Submit. The reward is added instantly.
Copy the code from our codes list instead of typing it. Most codes in this game are lowercase and use underscores, and one wrong character is enough for it to fail.
Why a code doesn't work
- You're in a run. Leave to the lobby and try again from the Diamond menu.
- A typo or a missing underscore. Paste the code without spaces before or after it.
- The code has expired. Codes usually run out after an update or when a limited event ends. We move them to the expired table as soon as sources confirm it.
- You already used it. Each code works once per account.
- The game didn't update yet. If a code was released minutes ago, join a new server so you get the latest version.
Chat codes during fishing
Some rewards don't use the Codes menu at all. A few codes are typed into the in-game chat while you fish, which is why they show up in our FAQ rather than the main list. If a code page says it's a chat code, follow those instructions instead.
Tips
- Redeem new codes quickly. Diamond codes tied to milestones and events don't last long.
- Diamonds are best saved for a class you'll actually play, so check our beginner guide before spending them.
- Ignore sites listing "codes" like NIGHTS2026. If a code isn't confirmed by two sources, we don't publish it.
