How to Get Diamonds in 99 Nights in the Forest — All Free Methods

Learn every free way to get diamonds in 99 Nights in the Forest: chest farming, code redemption, Cultist Stronghold speedruns, and team strategies.

What Are Diamonds For in 99 Nights in the Forest?

Diamonds are the premium currency in 99 Nights in the Forest. Unlike regular resources you gather from the environment, diamonds are used to unlock powerful classes that change your entire playstyle. The most important purchases include:

  • Archer — a ranged class that excels at keeping enemies at a distance
  • Mage — a magic-based class with powerful area-of-effect abilities
  • Other premium classes that provide unique advantages in both solo and team play

Since diamonds can only be obtained through a handful of specific methods, knowing the most efficient routes is essential. This guide covers every verified free method for earning diamonds, so you can unlock your preferred class as fast as possible.

Method 1: Farming Chests for Diamonds

The most consistent way to earn diamonds is by opening treasure chests scattered across the map. Each chest type has a chance to contain diamonds, and they refresh on a timer.

Which Chests Give Diamonds

The following chest types have been confirmed to drop diamonds:

Chest TypeDiamonds Per ChestRespawn Time
Common Chest1 diamond~30 minutes
Legendary Chest1 diamond~30 minutes
Cold Chest1 diamond~30 minutes
Ice Chest1 diamond~30 minutes
Iron Chest1 diamond~30 minutes
Good Chest1 diamond~30 minutes
Gold Chest1 diamond~30 minutes

Each chest type spawns independently and grants 1 diamond per opening. Because they each respawn on their own ~30-minute timer, you can create a farming route that hits multiple chest locations in sequence and loops back as they refresh.

Chest Farming Tips

  • Learn the map: Memorize chest spawn locations across all biomes so you can move efficiently between them
  • Track respawn timers: Note the time you open each chest and return after 30 minutes
  • Prioritize high-traffic areas: Some chest locations are contested by other players — visit less popular spawns first
  • Play during off-peak hours: Fewer players means less competition for chests

With a good route hitting 5-6 different chest types, you can reliably collect 5-6 diamonds every 30 minutes. That adds up quickly when you're dedicated to farming.

Method 2: Redeeming Codes for Free Diamonds

The fastest way to get diamonds without any grinding is through promo codes. The developers regularly release codes that reward free diamonds and other items.

How to Redeem Codes

  1. Open 99 Nights in the Forest in Roblox
  2. Look for the codes or settings menu in-game
  3. Enter the code exactly as written (codes are case-sensitive)
  4. Confirm to receive your rewards

Where to Find Active Codes

We maintain an up-to-date list of all working codes on our 99 Nights in the Forest codes page. Codes are typically released during updates, holidays, and special events. Check back regularly — codes expire without notice, so redeem them as soon as they appear.

Code Redemption Tips

  • Redeem immediately: Codes can expire at any time — don't wait
  • Follow the developers: New codes are often announced on the game's official social channels
  • Check our codes page: We verify and update the list daily so you don't have to search

Method 3: Cultist Stronghold Speedrun

For players willing to engage in combat, the Cultist Stronghold offers a repeatable source of diamonds through a speedrun strategy.

What Is the Cultist Stronghold?

The Cultist Stronghold is a combat-focused area in the game where you face waves of cultist enemies. Completing runs through this area can reward diamonds, making it a viable farming method for skilled players.

Speedrun Strategy

  1. Gear up properly — bring your best weapons and armor before entering the Stronghold
  2. Learn enemy patterns — cultist enemies have predictable attack cycles you can exploit
  3. Move efficiently — don't waste time on unnecessary fights; focus on clearing the path to the reward
  4. Repeat — once you complete a run, restart and do it again

The Stronghold approach works best once you've already unlocked a strong class. If you're still using the default class, consider grinding chests and codes first to unlock Archer or Mage before attempting repeated Stronghold runs.

Team Play Tips for Faster Diamond Farming

Playing with a team dramatically increases your diamond earning rate. Here's how to maximize efficiency through coordination.

Form a Farming Squad

The most effective approach is to join the game's community Discord and form a dedicated farming group. Benefits include:

  • Chest route splitting: Each team member takes a different section of the map, covering more ground in the same time
  • Stronghold carries: Experienced players can help newer ones clear the Cultist Stronghold
  • Code sharing: Team members can alert each other when new codes drop
  • Timing coordination: Synchronize chest farming to hit all respawn windows

Team Composition for Stronghold Runs

RoleClass SuggestionJob
TankDefault or unlocked tank classAbsorb damage, draw aggro
DPSArcher or MageHigh damage output on cultists
SupportAny class with healing itemsKeep the team alive

A 3-4 player team can clear the Cultist Stronghold significantly faster than solo players, resulting in more diamond rewards per hour.
