What are the codes in 99 Nights in the Forest?

Two codes are currently active as of April 2026, both verified by multiple gaming outlets. The most generous is afterparty, which rewards 15 gems or diamonds depending on your game version (Pocket Tactics, thespike.gg). The second code, yay fishing, gives 2 gems or diamonds—but it requires you to be actively fishing when you type it into chat (Pocket Tactics).

Active codes

  • afterparty — 15 gems/diamonds (standard redemption via lobby menu)
  • yay fishing — 2 gems/diamonds (chat command while fishing)

Expired or unconfirmed codes

  • YouTube videos mention codes like “aft” and “ni” as active, but these are not verified by established gaming sites (YouTube)
  • thespike.gg lists “happyhalloween” for 10 Candy, but this is a seasonal code with unclear current status
Bottom line: The “afterparty” code delivers the most gems in a single redemption. The “yay fishing” chat code is useful if you’re already hunting fish, but it won’t work from the lobby menu.

Players who stack both active codes end up with 17 gems total—a modest but tangible start for new character builds.

How to get 100 free gems in 99 nights?

No single code currently gives 100 gems in 99 Nights in the Forest—the highest verified reward is the 15 gems from “afterparty” (Pocket Tactics). However, stacking both active codes gives you 17 gems total, and the game runs regular events that introduce new codes with potentially larger rewards.

Redeem active codes

  • Enter the lobby (codes don’t work during active gameplay)
  • Find the diamond icon in the bottom-left corner of the screen
  • Click it to open the code redemption window
  • Type a valid code exactly as listed (codes are not case-sensitive)
  • Press enter—if the code is active, your gems or diamonds appear instantly

Special redemption steps for chat codes

  • The “yay fishing” code requires you to be in a fishing activity first
  • Type the command exactly in the in-game chat while fishing is active
  • Rewards grant 2 extra gems or diamonds beyond normal fishing loot
The upshot

Codes redeem once per account and expire after a limited window, according to thespike.gg. Redeem them as soon as you spot them rather than waiting.

What this means: waiting for a bigger code release could cost you the 17 gems available right now.

How to find codes in 99 Nights in the Forest?

There is no official developer site for 99 Nights in the Forest codes. Grandma’s Favorite Games hasn’t set up a dedicated code page, so players rely on community resources and gaming publications to track active codes (PC Gamer).

Check official sources

  • The Fandom Wiki maintains a community-edited codes page
  • Roblox group announcements sometimes tease upcoming codes during events

Wiki and update pages

  • PC Gamer publishes periodic code roundups with game history context
  • Pocket Tactics checked for new codes on April 21, 2026
  • thespike.gg lists active codes with detailed usage explanations
  • G2A News offers pro tips on lobby restrictions and code strategies
Why this matters

Multiple YouTube creators updated their code lists in April 2026 following bug fixes and offerings updates, according to video changelogs. Cross-reference at least two sources before spending time redeeming.

What this means: relying on a single source risks wasting time on expired codes when verification takes under a minute.

How to get free diamonds in 99 Nights in the Forest?

The “afterparty” code rewards either gems or diamonds depending on your version’s terminology—both currencies work the same way in the Daily Class Shop, where players spend them to unlock new classes and reroll talents (PC Gamer).

Diamond codes

  • “afterparty” — 15 gems or diamonds (most consistent across sources)
  • No separate diamond-exclusive codes have been confirmed as active in April 2026

Gem vs diamond distinction

  • Both currencies appear to be interchangeable in the game’s economy
  • Gems/diamonds unlock new classes and reroll character talents
  • The Daily Class Shop rotates offerings requiring these currencies
The catch

Third-party sites claiming free diamond generators or top-up codes are not valid—codes only come from in-game redemption, developer announcements, or verified gaming outlets.

What this means: players who chase “diamond generators” from unverified sites risk account exposure with no reward.

What are 99 Nights in the Forest codes for gems?

Every active code listed in this article rewards gems or diamonds. The game introduced codes during the volcano event after its September 2025 launch, and the developer continues adding codes through updates (PC Gamer).

  • Seasonal codes like “happyhalloween” (10 Candy) appeared on thespike.gg
  • No codes for 700 gems in a single redemption have been confirmed

Taming and Christmas codes

  • Christmas update codes are not listed as currently active by any verified source

What to watch

Surviving longer in 99 Nights in the Forest is much easier when you take advantage of free rewards from codes, according to thespike.gg. Each code redeemable is a tangible boost to your character build.

The implication: players ignoring codes are leaving free class unlocks on the table compared to those who stay current.

How to redeem codes in 99 Nights in the Forest (steps)

The redemption process takes under a minute once you’re in the right screen. Codes are not case-sensitive and require no level minimum, making them accessible to new players (GamesRadar).

  1. Load into 99 Nights in the Forest and wait for the lobby screen to fully load
  2. Locate the diamond icon in the bottom-left corner of the screen
  3. Click the icon to open the code redemption panel
  4. Enter the code (type exactly—”afterparty” or “yay fishing”)
  5. Press the submit or enter button
  6. Check for an instant reward notification in the bottom-left UI
The trade-off

Codes only work in the lobby—you cannot redeem them during active survival gameplay. The exception is chat codes like “yay fishing,” which require you to be doing the specific activity first. For those interested in the team’s performance, you can find the Posiciones SC Freiburg clasificación on our site.

What this means: attempting to redeem during a match wastes time since the system simply won’t process it.

  • “yay fishing” requires fishing activity to trigger
  • Redemption via diamond icon in bottom-left lobby
  • Codes not case-sensitive
  • One-time use per account
