All Active 99 Nights in the Forest Codes (October 2026)

99 Nights in the Forest codes give free Diamonds and Flames, the two rewards that matter most outside of a run. Diamonds buy classes and talents in the lobby, and Flames force useful events like the Frog event or a free garden on your map.

In this article, we'll list every working code with its exact reward, explain what to spend the rewards on, and show how to redeem codes and fix the common errors.

99 Nights in the Forest Codes

99 Nights in the Forest is a co-op survival horror game made by Grandma's Favourite Games, a three-person studio from New Zealand. New codes usually arrive with a big update or milestone, like the June 2026 "The Forest Wakes Up" update or the September 2026 Roblox Innovation Award win.

Active 99 Nights in the Forest Codes

These are the codes that work right now. All three were checked on October 18, 2026.

The Flames from awardwinner_yay and forestwakesup26 are random, so two players can get different ones from the same code. Every code works once per account, so redeem all three before you start your next run.

Expired 99 Nights in the Forest Codes

These codes no longer work. They're listed so you don't waste time on them.

Some code sites still list happyhalloween as working because the 2026 Halloween event is live. The fan wiki marks it as expired, since the code was made for the 2025 event only.

What to Spend 99 Nights in the Forest Code Rewards On

The three active codes give 45 Diamonds in total. The table below shows what that buys in the Classes shop, using current prices.

New players get the most value from Scavenger, Camper, and Escape Artist together, since that uses exactly 45 Diamonds. Scavenger adds 2 sack slots, Camper slows hunger drain by 10%, and Escape Artist cuts the hunger penalty for sprinting.

The Classes shop also puts a few random classes on sale every 24 hours, at 10% to 20% off. Check the sale before you spend, since a 20% discount turns a 50-Diamond class into a 40-Diamond one.

Flames are used at the Campfire during a run, and you can light up to three per session. Use them early, since many Flames change the map and do nothing once you've explored it. These are the Flames most often reported from the two codes.

How to Redeem Codes in 99 Nights in the Forest

You redeem 99 Nights in the Forest codes in the lobby, not during a run. Follow these steps.

1. Launch 99 Nights in the Forest on Roblox and wait in the lobby.
2. Click the Diamond icon in the bottom-left corner, or walk up to the Currency Shop NPC.
3. Click the Codes button in the bottom-right corner of the Currency Shop.
4. Type or paste a code into the Enter Code box.
5. Press Submit, and the reward is added to your account right away.

Codes aren't case-sensitive, but paste them exactly as shown to avoid typos. The Currency Shop also has a separate Merch Codes section, which only accepts codes printed on official 99 Nights merchandise.

How to Use the yay fishing Chat Code

The yay fishing code doesn't go in the Codes box. It's a one-time chat trick that drops 2 Diamonds during a run. The fan wiki still lists it as working, but several guides now mark it as expired, so don't count on the Diamonds.

1. Start a game and upgrade the Campfire to level 2 to open the Fishing Shack area.
2. Take an Old Rod from the Fishing Shack.
3. Equip the rod and start fishing at a fishing hole.
4. Type yay fishing in the chat while you're fishing.
5. Pick up the 2 Diamonds, which can fall into the fishing hole.

This only works once per account, and it doesn't work for players with chat turned off.

99 Nights in the Forest Codes Not Working

Most failed codes come from one of five problems. Check this list before you assume a code is dead.

• Already used: Every code works once per account, so a second try shows an error.
• Wrong menu: Normal codes only work in the Codes section. They won't work in the Merch Codes box or in chat.
• In a run: Codes are redeemed in the lobby, so leave your current game first.
• Old server: Updates go live every other Saturday at 1 PM ET, so rejoin to load the newest version.
• Unverified code: The code SURVIVOR shows up on some sites, but no official source or wiki has confirmed it. Players report it fails most of the time.

Where to Find More 99 Nights in the Forest Codes

New codes are announced in the official 99 Nights in the Forest Discord server, which has more than 700,000 members. Update parties run every Saturday at 1 PM ET, and a new update goes live every other week.

• Discord: the official 99 Nights in the Forest server at discord.gg/nightsintheforest
• Roblox group: Grandma's Favourite Games, with more than 12.5 million members
• Developers on X: @Cracky4Roblox, @Foryxe, and @viridialRoblox, linked from the official 99-nights.com site
• Fan wiki: the 99 Nights in the Forest Wiki Codes page, which the community updates quickly

The developers rarely post codes on X, so Discord announcements are the most reliable place to see a new code first. Past codes dropped with major updates, an award win, and the 2025 Halloween event, which brought two codes.

Other Ways to Get Free Diamonds

Codes are a one-time boost, so most Diamonds come from regular play. These are the steady sources.

Update parties are another source, since the developers spawn free Diamonds during the 30-minute party before an update. Chests and the Cultist Stronghold don't give Diamonds in those matches, and the amount varies each week.
