Survival Advantage: Essential 99 Nights in The Forest Codes for October 2025

The chilling and captivating Roblox survival game, 99 Nights in The Forest, continues to engage its dedicated player base with frequent updates and, critically for any serious survivor, active promotional codes. As the game enters its intensified October 2025 season, marked by significant Halloween content updates and the new Potion Making mechanics, securing free in-game currency and items is more vital than ever. This guide provides the complete, verified list of active codes, offering a crucial edge to players looking to unlock the best classes and boost their chances of surviving the eerie 99 nights.

Code redemption is the fastest way for both new and veteran players to acquire free Diamonds (Gems) and Halloween Candy, high-value currency items used to purchase powerful Classes like the new Witch or the Trick or Treater, as well as essential supplies. Given the game’s focus on challenging resource management and wave-based defense against terrifying entities, these free rewards represent a high CPC (Cost Per Click) value for players seeking a major advantage.

All Verified and Working 99 Nights in The Forest Codes (October 2025)

The developers, Grandma’s Favourite Games, have rolled out new codes coinciding with the substantial Halloween event. Players must act fast, as these promotional codes are often temporary and tied to seasonal events, meaning they can expire without prior notice. Check the list below for all currently active and tested codes:

• happyhalloween: Redeem this code for 10 Candy. This new currency is essential for buying limited-time Halloween items and classes.
• afterparty: Use this code to instantly receive 15 Gems (Diamonds). Gems are the premium currency used to unlock permanent new Classes.
• yay fishing: This special, lesser-known code awards 2-3 Gems. (Note: This code has a unique, in-game redemption process detailed in the guide below and may be marked as expired on some platforms, but remains intermittently active via the chat system for minor rewards.)

Players are strongly advised to capitalize on these limited-time offers to enhance their game progression and secure premium items. The Candy, specifically, is a short-term, high-value asset for the ongoing spooky season.

Breaking News: October 2025 Updates – Potion Making and New Classes

The survival landscape in 99 Nights in The Forest has drastically shifted with the mid-October “Potion Making” update (Source: IGN, Beebom, VG247). This major content drop is the second part of the game’s Halloween event and introduces complex new mechanics and strategic elements:

• Potion Making System: Players can now forage for new, unique ingredients—such as Moonflower, Stareweed, Cave Vine, and Mandrake Plant—to concoct Trick Potions and Treat Potions at their base.
• New Classes: The Halloween Shop, accessible via the currency NPC, features new permanent and temporary classes. The permanent Witch class (costing 900 Candy) offers powerful new abilities, while the Trick or Treater class (30 Candy) provides unique event utility.
• Strategic Depth: The new mechanics add a crucial resource layer beyond simple crafting and defense. Successfully mixing potions yields more Halloween Candy, creating a cyclical system where resource gathering directly funds high-tier class acquisition. This requires significant team coordination and resource allocation during the day phase, increasing the game’s overall challenge and replayability.

Redemption Instructions: Claiming Your Free Gems and Candy

Redeeming the standard codes is a straightforward process, but the “yay fishing” code requires a specific sequence of in-game actions.

Standard Code Redemption Steps:

1. Launch the 99 Nights in The Forest experience on Roblox.
2. Ensure you are in the pre-game Lobby (matchmaking area), not an active round.
3. Locate and select the Diamond Icon (Gems button) typically found in the lower-left corner of the screen.
4. In the shop menu that appears, select the blue “Codes” button, usually in the bottom-right corner.
5. Enter the active code (e.g., happyhalloween) into the text box. Copying and pasting is recommended to avoid typos.
6. Click the “Submit” button to instantly receive your free rewards.

“yay fishing” Special Redemption Steps:

The “yay fishing” code is redeemed directly through the in-game chat, requiring a moment of downtime during a match:

1. Start a new solo or multiplayer round.
2. Upgrade your Campfire to Level 2 to unlock higher-tier crafting.
3. Locate the Fishing Shack and pick up an Old Rod.
4. Go to any fishing hole and begin fishing.
5. While the fishing animation is active, press the “/” key on your keyboard (or open the in-experience chat on mobile/console).
6. Type the exact phrase: yay fishing and hit Enter. You should receive a small reward of 2-3 Gems.

Warning: Always ensure the spelling and capitalization are exact for all codes, as they are typically case-sensitive. If a code fails, it is most likely expired or has been entered incorrectly.

Optimal Survival Strategy: Maximizing October’s New Features

The October updates have significantly altered the survival meta. To maximize your chances of reaching the legendary 99th night, players should integrate the new features and free code rewards into their strategy:

• Early Class Acquisition: Use the free Gems from the afterparty code to purchase a strong early-game class. Classes like the Lumberjack or Miner are excellent investments for their resource-gathering perks, which are crucial for the new potion-making mechanics.
• Candy-to-Power Pipeline: Prioritize using the happyhalloween code’s Candy and the Candy earned from potion-making to unlock the permanent Witch class. This class is designed to handle the new challenges and offers long-term competitive advantage over the game’s increasingly difficult entity waves (The Deer, Owl, and Cultist invasions).
• Focus on Potion Ingredients: Dedicate a portion of the day phase to finding the new Halloween potion ingredients. The most efficient strategy is to give 10 Flowers to the Fairy NPC to have her plant the required Cave Vine, Stareweed, and Moonflower Seeds across the map, securing a steady supply for high-value Candy production.
• Cooperative Play is Key: With more diverse resources and mechanics, multiplayer is highly recommended. Allocate roles: one player for defense/base upgrades, another for resource gathering/potion ingredients, and a third for map exploration/child rescues. Effective communication remains a critical key performance indicator (KPI) for survival.

In conclusion, the October 2025 updates to 99 Nights in The Forest have brought an exciting, complex layer of strategy to the survival horror experience. By quickly redeeming the active codes for free Diamonds and Candy, and mastering the new Potion Making system, players can ensure their base is fortified and their Classes are optimized to overcome the terrifying challenge of 99 nights in the dark, haunted woods.
