All 99 Nights in the Forest codes (January 2026)

The following codes are known to give rewards in January 2026.

Both working options are one-time use per account. Once you have claimed them, they cannot be redeemed again.

How to redeem 99 Nights in the Forest codes

Standard codes such as afterparty are redeemed through the in-game Diamonds menu.

Step 1: Launch 99 Nights in the Forest on Roblox and wait until you are fully loaded into the lobby or your camp.

Step 2: Look at the bottom-left of the screen and click the button with the Diamonds (or Gems) icon next to the green plus symbol to open the currency shop.

Step 3: In the currency shop window, find the blue Codes button on the right-hand side or along the bottom and select it.

Step 4: Click inside the text box, carefully type or paste a working code exactly as shown (for example, afterparty), then press Submit.

Step 5: If the code is valid and unused, the Diamonds are added to your account immediately; if it fails, the game shows a short message explaining whether it is invalid, expired, or already redeemed.

Tip: Codes are case-sensitive, and extra spaces at the start or end will cause them to fail. Copying the code directly and pasting it into the box helps avoid typos.

How the “yay fishing” code works

The phrase yay fishing does not use the normal Codes menu. It is a hidden trigger tied to the fishing minigame.

Step 1: Start a run and progress your camp until you can access fishing. This requires upgrading the campfire to at least Level 2 so that the fishing shack and Old Rod become available.

Step 2: Obtain any Fishing Rod and move to a fishing spot so that you are actively in the fishing minigame.

Step 3: While holding the Fishing Rod and standing at the fishing location, open the in-game chat.

Step 4: Type yay fishing in chat and send the message. If all conditions are met, two Diamonds drop from the sky for you to pick up.

Note: This interaction only works once per account. If nothing happens, check that you are in an active game (not the lobby), are actually fishing with a rod in hand, and that you have not already triggered it before.

What 99 Nights in the Forest codes give you

Redeeming codes currently focuses on Diamonds, the premium currency used to buy classes and certain upgrades. Between afterparty and the yay fishing trigger, you can secure a total of 17 free Diamonds if you have not used them before.

Diamonds are particularly valuable early on because stronger classes often come with improved stats and more practical starting items, giving you a better chance of surviving the later nights and tougher enemies.

Why a code might not work

Several common issues can stop a 99 Nights in the Forest code from redeeming correctly.

• Typos or wrong casing: Codes must match exactly. Extra spaces or incorrect letters will return an error.
• Already redeemed: Each code can be used only once per account. If you have claimed it before, it cannot be used again.
• Expired event codes: Seasonal codes such as happyhalloween only work during their event window. After that, they stay listed historically but no longer grant rewards.
• Wrong activation method: yay fishing must be typed in chat during the fishing minigame, not in the Codes menu.

If a code fails and you are sure it is typed correctly and has not been used before, waiting a short time and restarting the experience can help in case of temporary server issues.

How to get more Diamonds beyond codes

Once you have claimed the available codes, Diamonds mainly come from regular gameplay and progression.

• Opening chests around the forest, including Common, Good, Iron, Gold, Ice, Cold, and Legendary variants, which can drop Diamonds alongside items.
• Reaching certain milestone days, such as Day 50 and Day 99, which award extra Diamonds.
• Completing in-game badges, which can include Diamond rewards.

There are no legitimate admin-command style “cheat codes” for extra Diamonds. Any claim that ordinary players can receive admin privileges to spawn Diamonds is misleading; only staff have internal tools, and these are not shared with the general player base.

New 99 Nights in the Forest codes are shared through the game’s official community channels, especially the Discord server. Checking those announcements periodically is the best way to catch any future codes as they appear.
