99 Nights in the Forest Codes (September 2026)

99 Nights in the Forest is a Roblox co-op survival horror game where players build up a camp, keep a campfire burning, and try to make it through 99 in-game nights while a deer-like creature, cultists, and other threats close in. Rescuing four missing children scattered across the map lowers the number of nights needed to win, giving players a shortcut through the standard grind.

The game comes from developer Grandma's Favourite Games and has been live on Roblox since March 2025, picking up more than 29B visits since launch. Diamonds are the main currency, spent on character classes and other unlocks, and codes are one of the quickest ways to pick up a few extra without grinding for them.

In this article, we'll explore all the active and expired 99 Nights in the Forest codes, how to redeem each one, and where new codes tend to show up first.

How 99 Nights in the Forest Codes Work

99 Nights in the Forest codes are short phrases released by the developers that hand out free Diamonds and other small bonuses when redeemed through the in-game Currency Shop.

Below you'll find every code that's currently active, along with the ones that have already expired.

Active 99 Nights in the Forest Codes

These are the codes still working right now. Type or paste them exactly as shown, since a typo is usually why a code won't go through.

Both codes redeem the same way through the Currency Shop, and neither is tied to a specific event or time window, so there's no rush to use them before they expire.

Expired 99 Nights in the Forest Codes

These codes no longer give out anything, but they're listed here so you're not wasting time trying to redeem one that's already dead.

Happyhalloween was tied directly to the Halloween event and stopped working once it wrapped up, so it's unlikely to return unless the event itself comes back around.

How to Redeem Codes in 99 Nights in the Forest

Redeeming forestwakesup26 and afterparty only takes a few taps through the Currency Shop. Here's how.

1. Open the main lobby and click the Diamond icon in the bottom-left corner, or talk to the currency NPC instead.

2. This opens the Currency Shop. Click the Codes button in the bottom-right corner of that menu.

3. Type or paste the code into the text box exactly as shown.

4. Hit Submit to claim the reward.

Neither code is case-sensitive, and neither uses numbers in place of letters, so typing them in as plain lowercase works fine.

Where to Find More 99 Nights in the Forest Codes

The official Discord server is the best place to catch new codes early, since they tend to show up there alongside general updates before spreading anywhere else. The game's X account, run by one of the developers, studioGrandma's Favourite Studio, also shares codes from time to time.

Unlike some other Roblox games, there's no official Trello board here, so the Discord server and in-game loading screens are the two spots worth checking regularly when a new code drops.

Final Words

99 Nights in the Forest doesn't hand out a huge number of codes, but the ones that exist are worth grabbing while they last, especially since Diamonds go straight toward character classes and other unlocks. Check the Discord server every so often, since new codes tend to show up there before anywhere else.
