If you’ve been wandering through the haunted woods of 99 Nights in the Forest on Roblox, you already know that diamonds (also called gems) are absolutely essential for unlocking powerful classes that’ll dramatically improve your survival odds. I’ve spent countless nights navigating this terrifying survival horror experience, and I’m here to share every single method I’ve discovered for farming diamonds efficiently.
Diamonds serve as the premium currency in this game, letting you purchase classes from the Daily Class Shop and roll for talents that give your character special perks. Whether you’re a free-to-play grinder or looking for the fastest farming methods, this comprehensive guide covers all eight proven ways to get diamonds in 99 Nights in the Forest.
| Method | Diamond Yield | Difficulty | Renewable |
|---|---|---|---|
| Cultist Stronghold | 5 diamonds | Hard | Yes (20-min cooldown) |
| Badges | 100+ total | Varies | No (one-time) |
| Surviving Days | 2-5 per run | Medium | Yes |
| Chests | 1 diamond | Easy | Yes |
| Codes | 15+ gems | Very Easy | Limited |
| Yay Fishing Easter Egg | 2 diamonds | Easy | No (one-time) |
| Update Party Events | Variable | Easy | Event-only |
| Currency Shop | 20-700 | N/A | Yes (Robux) |
Before we jump into the farming methods, let me explain what makes diamonds so valuable. In 99 Nights in the Forest, diamonds are your ticket to unlocking the game’s 28+ classes. Each class offers unique starting equipment, abilities, and playstyles that can completely transform your survival strategy.
For example, the Medic class spawns with healing items perfect for supporting your team, while the Ranger provides a revolver and flashlight ideal for dealing with the terrifying bipedal deer monster. Without diamonds, you’re stuck with the basic survivor class, which puts you at a significant disadvantage as you progress through the increasingly difficult nights.
Beyond class unlocks, diamonds let you roll for talents special perks that enhance your character’s capabilities. With talent costs ranging from a few gems to dozens depending on rarity, you’ll need a steady diamond income to optimize your builds.
The Cultist Stronghold is hands-down the most efficient renewable method for diamond farming. I discovered early on that this three-story fortress filled with hostile cultists contains a secret chamber on the top floor with both a Ruby Chest and a Diamond Chest that rewards 5 diamonds per successful run.
The stronghold appears on your map as a three-diamond symbol inside a grey circle. It spawns in different locations each match, so you’ll need to explore during daylight hours to locate it. Once you’ve found it, I recommend marking its position and preparing properly before attempting a raid.
After dozens of runs, I’ve perfected a solo raiding strategy that minimizes risk:
The stronghold resets every 20 minutes, making it the most reliable repeatable farming method. During weekend events with 2x gem multipliers, you can potentially earn 10 diamonds per run, translating to 30 diamonds per hour if you’re efficient.
When playing with friends, coordinate roles for maximum efficiency:
Team raids are significantly faster and safer, allowing you to complete multiple runs per hour during the 20-minute cooldown periods.
Badge completion is my top recommendation for newer players because it frontloads a massive diamond reward. There are approximately 35-42 badges available in 99 Nights in the Forest, and collectively they reward over 100 diamonds as one-time bonuses.
Each badge’s diamond reward equals its star rating. A 3-star badge grants 3 diamonds, a 5-star badge gives 5 diamonds, and so on. The beauty of this system is that many badges require activities you’ll naturally complete while learning the game.
Here are the badges I prioritize when starting a fresh account:
Survival Milestones:
Campfire Upgrades: Upgrading your campfire to levels 2, 3, 4, and 5 each grants badge diamonds. Since campfire upgrades expand your exploration radius and improve crafting options, you’re earning diamonds while strengthening your base.
Exploration Badges: Discovering specific locations like the Fishing Shack, Pelt Trader, and various forest landmarks rewards badges. Use a crafted map to expedite exploration and mark important locations.
Some badges require significant skill but offer proportionally higher diamond rewards:
I recommend focusing on the easier badges first to accumulate diamonds quickly, then tackling the challenging ones as you improve. The key insight is that badges provide a guaranteed diamond source that doesn’t rely on RNG or combat difficulty.
Simply surviving earns you diamonds at specific thresholds. The game rewards persistence with:
This method synergizes beautifully with badge farming since you’ll naturally hit these milestones while completing survival badges. Every successful 99-day run effectively gives you 5 diamonds plus whatever badges you earn along the way.
After experimenting with different strategies, here’s my proven approach for consistently reaching Day 99:
Days 1-20 (Foundation Phase):
Days 21-50 (Preparation Phase):
Days 51-80 (Consolidation Phase):
Days 81-99 (Survival Mode):
The difference between surviving to Day 99 and dying on Day 80 often comes down to preparation. Stock resources during the early days when threats are manageable, then rely on those reserves during the final brutal nights.
Chests scattered throughout the forest occasionally contain single diamonds as rare loot drops. While this isn’t the most efficient primary farming method, it’s excellent passive diamond income while exploring or gathering resources.
Not all chests are created equal. Diamonds can appear in:
The drop rate is fairly low I’d estimate roughly 1 in 20 chests contains a diamond based on my experience. However, since you’ll naturally open hundreds of chests during a typical playthrough, the diamonds add up over time.
To maximize chest discoveries:
Craft a Map: Maps reveal nearby points of interest including chest locations. This single item dramatically increases your farming efficiency.
Explore Systematically: Clear the map in a grid pattern rather than wandering randomly. Mark locations you’ve already searched to avoid backtracking.
Check High-Value Locations:
Bring Inventory Expansion: Visit the Pelt Trader early with a bunny pelt and choose the Good Sack upgrade. This increases your carrying capacity, letting you collect more loot per exploration trip without returning to base.
I typically find 2-4 diamonds from random chests during a full 99-day run, which isn’t massive but contributes to your overall diamond total.
Codes are absolutely the fastest way to get free diamonds without grinding. Developers release promotional codes during updates, events, and milestone celebrations that instantly grant diamonds when redeemed.
As of October 2025, here are the verified working codes:
HAPPYHALLOWEEN – Rewards 10 Candy (Halloween 2025 event currency) afterparty – Rewards 15 Gems/Diamonds (First-ever code, released September 2025)
These codes are case-insensitive, so don’t worry about capitalization when entering them.
The redemption process is straightforward:
If you receive an error message, double-check that you’ve typed the code correctly. Codes cannot be redeemed twice on the same account, and expired codes will return a “Code Invalid” message.
Since the code system only launched in September 2025 with the Volcano Part 2 update, we’re still establishing release patterns. Based on developer behavior, expect new codes during:
The best sources for codes are:
I recommend bookmarking reliable code websites that update frequently and checking back after every game update. Missing a limited-time code means potentially losing 15+ free diamonds.
This hidden method is incredibly easy but only works once per account. I stumbled upon it accidentally and was thrilled when 2 free diamonds appeared.
Follow these exact steps:
This is a one-time reward, but it’s essentially free diamonds for spending 5 minutes. I always grab this early in my playthroughs since it helps fund my first class unlock.
Update parties are special admin-hosted events that occur approximately one hour before major game updates, typically on Saturdays. During these events, administrators spawn diamonds and other rewards directly for players to collect.
When an update party is active:
The diamond rewards vary dramatically depending on admin generosity and your collection speed. I’ve seen players report earning anywhere from 10 to 50 diamonds during particularly generous update parties.
To get the most diamonds during update parties:
Monitor Announcements: Join the Discord server and enable notifications for the announcements channel. Developers typically give 1-2 hours notice before update parties begin.
Join Early: The game mode fills up quickly. Join the moment it becomes available to secure your spot.
Move Quickly: Diamonds spawned by admins disappear if not collected within a time limit. Stay mobile and grab everything you see.
Follow Admin Instructions: Sometimes admins will announce locations where they’re spawning diamonds. Pay attention to chat.
While update parties aren’t reliable farming since they happen infrequently, they’re excellent opportunities for bonus diamonds. Mark your calendar for update days (usually Saturday evenings) and participate whenever possible.
The final option is the most straightforward but requires real money. The Currency Shop in the lobby lets you purchase diamond packages using Robux.
The shop offers four tiers:
The 250 and 700 diamond packages offer slightly better value, but honestly, none of these purchases are particularly cost-efficient compared to the free farming methods.
My personal recommendation: Only purchase diamonds if you have spare Robux and value convenience over time investment. Everything in 99 Nights in the Forest can be earned through free-to-play grinding, and the diamond costs for classes aren’t unreasonably high.
If you do decide to buy, I suggest the 100-diamond package as a one-time purchase. This gives you enough to unlock 1-2 mid-tier classes immediately, jumpstarting your progression without breaking the bank.
For most players, combining badges, stronghold farming, and codes provides more than enough diamonds to unlock your desired classes over time.
After mastering all the diamond sources, I’ve developed an optimal farming routine that maximizes diamond income per hour:

Session 1 (New Account):
Session 2-10 (Early Grinding):
Session 11+ (Optimized Farming):
Using this method, a dedicated player can earn 100+ diamonds within the first week, enough to unlock multiple classes and experiment with different playstyles.
Now that you know how to farm diamonds, let’s discuss optimal spending:
Your absolute first purchase should be a class that matches your playstyle:
Once you have one reliable class, diversify:
After securing your core classes, invest in talents. The best talents dramatically improve class effectiveness, but be prepared for RNG. It might take multiple rolls to get desirable perks.
Avoid these diamond traps:
Through trial and error, I’ve identified several mistakes that slow down diamond accumulation:
Mistake 1: Ignoring Badges New players often focus solely on survival while neglecting badge objectives. Since badges provide the largest one-time diamond infusion, this is extremely inefficient. Check the badge menu regularly and actively work toward achievable goals.
Mistake 2: Dying Before Day 50 Many players play too aggressively early and die on Days 30-40. Conservative play ensuring you reach at least Day 50 guarantees 2 diamonds plus accumulated badges. Survival trumps risky diamond hunting.
Mistake 3: Solo Stronghold Attempts Without Preparation Raiding the Cultist Stronghold unprepared leads to death and wasted time. Always bring appropriate equipment, heal between floors, and retreat if necessary. Five diamonds aren’t worth losing 40 days of progress.
Mistake 4: Not Redeeming Codes Immediately Codes expire without warning. I’ve seen players miss 15-diamond codes because they waited “until later.” Redeem codes the moment you discover them.
Mistake 5: Buying Random Classes Impulse purchasing classes without researching their abilities wastes diamonds. Read class descriptions, watch gameplay videos, and choose classes that synergize with your preferred strategy.
Mistake 6: Farming Chests as Primary Method Chests should be supplemental income, not your main farming focus. The drop rates are too low to justify dedicated chest hunting. Farm chests while completing other objectives, never as the sole activity.
Take advantage of precise controls for stronghold combat. Keybind healing items and weapons to accessible keys for quick swapping during intense fights.
Diamond farming on mobile is more challenging due to touch controls. Focus on badges and codes rather than stronghold combat. When you do attempt strongholds, use the lock-on targeting feature aggressively.
Controller support makes combat more manageable than mobile but less precise than PC. Use controller vibration feedback to detect nearby enemies during stronghold raids.
I recommend keeping a simple spreadsheet or note tracking:
This helps identify which methods work best for your playstyle and ensures you’re making consistent progress toward diamond goals.
Recent game updates have adjusted diamond availability:
Halloween Update (October 20, 2025):
Taming Update (October 4, 2025):
Volcano Part 2 Update (September 2025):
Stay updated with patch notes as developers frequently adjust diamond sources and add new farming opportunities.
The exact total varies since class costs range from 30 to 200+ diamonds. Expect to need 2,000-3,000 diamonds to unlock every class in the game. However, most players only need 3-5 classes to cover all situations effectively.
No, diamonds are account-bound and cannot be traded, dropped, or transferred. Any player claiming to trade diamonds is scamming.
Yes! Diamonds are permanent currency tied to your account. Once earned, they persist across all game sessions until spent on classes or talents.
Using the methods in this guide, expect 100 diamonds within 5-10 hours of gameplay. Badge completion and codes provide the fastest initial diamonds, while stronghold farming maintains steady long-term income.
The developers actively patch exploits, and using them risks account bans. Stick to legitimate farming methods outlined in this guide.
No, the Pelt Trader only accepts wolf pelts and offers equipment/inventory upgrades. She doesn’t provide diamonds.
Chests respawn their contents each new game session, giving you repeated chances to find diamonds from chest RNG.
Redeem all active codes (15 diamonds), complete 15-20 easy badges (15-20 diamonds), use the yay fishing method (2 diamonds), and farm the Cultist Stronghold 2-3 times (10-15 diamonds). Total time: 2-3 hours.
The Survival Kit pass (299 Robux) provides starting equipment advantages but doesn’t give diamonds. If you’re spending Robux, diamonds are more universally useful since they unlock classes permanently.
No, diamonds never expire or disappear. Your diamond balance remains intact even if you take breaks from the game.
Diamond farming in 99 Nights in the Forest requires a balanced approach combining multiple methods. Badge completion and codes provide explosive initial diamonds, while Cultist Stronghold farming sustains long-term income. Survival milestones and random chest drops supplement your diamond income passively.
My biggest advice: Start with badges and codes for quick diamonds, invest in one solid class, then establish a stronghold farming routine. Within a few sessions, you’ll have enough diamonds to unlock your dream class setup and compete at the highest levels.
The key is consistency. Farm strongholds during every play session, work toward badge requirements naturally, and immediately redeem new codes when they drop. Diamonds accumulate faster than you’d expect with disciplined farming.
Now get out there, survive those 99 terrifying nights, and build your diamond fortune. The forest is waiting, and with the strategies in this guide, you’ll never lack the diamonds needed to survive its horrors.
Stay safe out there, and remember: that bipedal deer is always watching. But with the right classes unlocked using your hard-earned diamonds, you’ll finally have the tools to fight back.
