These codes have been personally tested and confirmed active as of August 10, 2026. Copy them exactly — case matters in some redeem menus, so paste rather than type.

afterparty	15 Diamonds	✅ Working	Jungle Biome Pt.2 launch celebration code

Expired 99 Nights in the Forest Codes — Don't Waste Your Time

These codes no longer work. Save yourself the frustration of entering them and getting the dreaded "Invalid Code" popup — which is the game's polite way of telling you you're living in the past.

Expired Code	Previous Reward	Why It Expired
happyhalloween	10 Candy	Seasonal Halloween event code
JUNGLESTART	15 Diamonds	Disabled after initial Jungle Biome patch
VOLCANOFIX	10 Diamonds	Volcano update bug-compensation code
JUNGLEPART2	15 Gems	Jungle Biome Pt.2 launch (now superseded)
FORESTGIFT	5 Diamonds	Early launch promotional code

How to Redeem Codes in 99 Nights in the Forest — Step by Step

The code menu only appears in the lobby — you can't access it mid-run. Get your codes in before you drop into the forest.

Launch 99 Nights in the Forest on Roblox. Head to the game page or use the direct Roblox link and hit Play.
Find the Currency Shop NPC in the lobby. Walk over to the Currency Shop — it's visible near the spawn area before you enter the forest.
Interact with the NPC to open the shop. Click or tap the NPC to bring up the Currency Shop interface.
Click the blue "Codes" button. It sits in the bottom-right corner of the shop window. Some older guides say to use the diamond icon — both routes lead to the same place.
Paste your code into the text box. Don't type it manually — paste directly from this page to avoid case or space errors.
Hit the Submit button. A "Code Redeemed!" confirmation pops up instantly when successful. Your diamonds appear in your account balance right away.

The Secret "Yay Fishing" Chat Code Nobody Tells You About

I love this one. While everyone is grinding the lobby code menu, there's a separate code hiding inside an active run — and it doesn't go in any code box. Type "yay fishing" directly into the Roblox in-game chat while you're holding a fishing rod and actively in the fishing minigame. Two diamonds will literally fall from the sky. It's small, sure. But when you're at night 47 and six diamonds short of unlocking the Hunter class, those two feel life-saving.

💡 Pro Tip: The "yay fishing" chat code requires Campfire level 2 and a crafted fishing rod. It won't trigger in the lobby — only during an active survival run while the fishing minigame is open. Plan for it as a mid-run bonus, not a starting reward.

Why Free Diamonds Actually Matter — The Class System Explained

Diamonds aren't cosmetic fluff. They're the only currency that unlocks classes — and the class you pick determines how every single run plays out. The two free codes above give you 30 diamonds combined. That's enough for the cheaper classes and a solid head start on the mid-tier ones. Here's the breakdown of the class cost tiers so you can plan your spending:

Cost (Diamonds)	Example Classes	Best For
10	Scout, Ranger	New players learning the loop
25–50	Hunter, Gatherer, Medic	Dedicated co-op roles and mid-game runs
100+	Lumberjack, Soldier	Experienced players pushing night 50+
500	Cyborg	Late-game combat dominance

"To find these behemoth playerbases you need to be on a platform like Roblox."

— Alec Kieft (Cracky4), developer of 99 Nights in the Forest, PC Gamer

The game won Best Adventure Experience and Best Horror Experience at the 2025 Roblox Innovation Awards, and a feature film adaptation was announced in April 2026. Those codes you're redeeming right now are for what is genuinely one of the biggest games in the world — act accordingly and spend those diamonds on something that'll last past night 10.

How to Get New 99 Nights Codes Before Anyone Else

New codes drop alongside major game updates, holiday events, and bug-compensation patches. Based on the pattern so far — Volcano hotfix, Jungle Biome Pt.1 and Pt.2, the Bee Biome update in late July 2026 — the developer releases codes roughly every 2–3 months around content milestones. Here's where to watch:

Official Discord server: Join via discord.com/invite/JyKTaU42ap — codes typically appear in announcements. There's no dedicated codes channel yet, so watch the general announcements section.
The Roblox game page itself: Developers occasionally drop codes in the game description during major update windows. Worth a quick check after any patch.
Developer X / Twitter: Follow Grandma's Favourite Games and the individual developers for milestone celebrations that often come with code drops.
Bookmark this page: This list updates whenever new codes drop — checking back after seasonal events (Halloween, Winter holidays) is your best bet for fresh ones.

⚠️ Important: Avoid any website or YouTube video promising "unlimited free diamonds" or "code generators." These are scams — no such tool exists for Roblox. The only legitimate source for free diamonds is official developer codes, the in-game Daily Class Shop grind, and chest drops during runs.

Why Isn't My 99 Nights in the Forest Code Working?

The redemption screen is brutally honest — "Invalid Code" means one of a short list of things went wrong. Run through these before assuming a code is dead:

You're in a match, not the lobby: Standard codes only work at the lobby Currency Shop. If you're already in night 34, you'll have to wait until the run ends.
Extra spaces from copy-pasting: A rogue space at the start or end of a pasted code triggers the invalid message. Paste, then check for trailing spaces.
The code has expired: Codes go dark after major patches with no warning. Cross-reference with the expired list above.
You've already redeemed it: Each code is one redemption per account. "Already Redeemed" means you got it on a previous session.
Server sync delay: Brand-new codes can take a few minutes to propagate across all servers. If the code just dropped in Discord, wait 5–10 minutes and try again.
Using chat method for a menu code (or vice versa): "Yay fishing" does not work in the Codes menu. Menu codes don't work in chat. Use the right method for each.
