How to Get Free Diamonds in 99 Nights?

Are there free codes for 99 Nights in the Forest?

Yes — as of September 2026, three working codes give free diamonds. The code forestwakesup26 rewards 15 diamonds plus 3 random flames, while afterparty gives 15 diamonds. A third option, yay fishing, is a chat phrase that grants 2 diamonds during the fishing minigame. All three are one-time use per account, as confirmed by Shane the Gamer.

No currently active code gives exactly 700 gems or diamonds. The highest reward is 15 diamonds from two codes. The rewards are small but consistent. Total free diamonds from all three active codes is 32 — still a nice pickup for a few minutes of work.

Bottom line: Three codes exist: forestwakesup26 (15 diamonds + flames), afterparty (15 diamonds), yay fishing (2 diamonds). For new players, use them immediately before they expire.

The catch: The diamond rewards are small — you won’t unlock everything with codes alone.

What Are the Cheat Codes for 99 Nights in the Forest?

The cheat codes are forestwakesup26, afterparty, and yay fishing. These are the only active codes as of September 2026. Each one rewards diamonds, with forestwakesup26 also granting three random flames.

forestwakesup26 is the top pick because it gives the most diamonds (15) plus three random flames, useful for enhancing equipment. afterparty comes a close second with 15 diamonds. yay fishing is a secondary phrase for extra diamonds during fishing.

  • forestwakesup26 — 15 diamonds + 3 random flames (GamesRadar)
  • afterparty — 15 diamonds (IGN)
  • yay fishing — 2 diamonds (Pocket Tactics)

The trade-off: Calling them “cheat codes” is a misnomer — these are official reward codes.

How Do I Activate Cheat Codes?

  1. Open 99 Nights in the Forest on Roblox.
  2. Find the Codes or Redeem section in the lobby.
  3. Enter the code exactly as shown.
  4. Submit and claim your reward.

For yay fishing, you need to be in the fishing minigame: type “yay fishing” in chat while the rod is cast (Pocket Tactics).

Where do I enter codes in 99 Nights in the Forest?

Codes are entered in the Codes or Redeem section, which is located in the main lobby of the game. Open the game, look for the Codes button on the screen, click it, and paste your code into the text field.

What to watch

If a code returns “invalid,” double-check your spelling and capitalization. The code forestwakesup26 is all lowercase — capital letters will break it.

Why this matters: A single mistyped character means losing a free reward.

The implication: Roblox’s policy on game exploits is strict, but redeeming legitimate codes is not an exploit.
