How to Get Free Diamonds in 99 Nights in the Forest (All Methods + Codes 2026)

If you play 99 Nights in the Forest, diamonds are the currency that decide how fast you unlock powerful classes and talents. They are the premium currency that you spend to buy new classes in the lobby and to roll or upgrade talents, so having a good free diamond strategy makes a huge difference to your progress.

This guide covers all the main free methods that still work in 2026. You will learn about current codes, stronghold farming, badges, survival milestones, daily quests and limited time events. You will also see which rewards are stable and which can change with updates, so you do not waste time on outdated tricks.

Quick overview of the best methods

If you want the fastest answer, start with these:

• Redeem all currently active codes such as afterparty, forestwakesup26 and the chat code yay fishing
• Farm the Cultist Stronghold, which gives around 5 diamonds each time you clear it
• Complete badges and survival milestones like Day 50 and Day 99 for a big one time boost
• Use daily quests and events like meteors and obsidian chest challenges as bonus income whenever they are active

Everything else in this guide adds detail around these core ideas.

What diamonds do in 99 Nights in the forest

Diamonds are the main premium currency in 99 Nights in the Forest. You use them to:

• Buy new classes in the lobby
• Buy or roll talents on those classes so you can create stronger builds

If you rely only on Robux purchases or one time codes, you will quickly run short on diamonds. A simple free farming plan lets you unlock useful classes earlier, reroll bad talents and survive longer runs.

Current codes for free diamonds

Codes are short strings that the developers share during updates. When you redeem them, you get diamonds or other rewards added to your account instantly.

How to redeem regular codes in the lobby:

1. Join 99 Nights in the Forest and stay in the main lobby
2. Click the diamond or currency icon to open the currency shop
3. Find and click the Codes button
4. Type the code exactly as shown and press Redeem

Codes can and do change when new updates arrive. Instead of trying to hold a full list inside this article, the best approach is to keep a few key examples here, then check fresh code lists or the official game page when you play.

How the yay fishing code works

Many players get confused with yay fishing because it does not work in the regular code menu. It is triggered in game while you are fishing.

To claim yay fishing:

1. Upgrade your campfire to Level 2
2. Buy a fishing rod at the fishing shop
3. Go to a lake or river and start fishing
4. While your line is in the water, open chat and type yay fishing

If done correctly, two diamonds appear near your character. You pick them up and the code is considered used. This is a nice early boost for any new campaign.

Cultist Stronghold farming

Once you can survive the early nights consistently, the Cultist Stronghold becomes your main repeatable way to earn diamonds.

Here is how it works:

• After around 20 minutes in a run, a large castle called the Cultist Stronghold opens
• You fight through several floors of cultists inside the stronghold
• At the top, there is a blue diamond chest that pays around 5 diamonds when you open it

You can clear the stronghold more than once in the same run as long as you live long enough. This turns it into a stable source of diamonds that you can farm over time.

Stronghold tips:

• Try to run strongholds with at least one friend so you can split enemies and revive each other
• Use the time between stronghold openings to work on other tasks like daily quests, badges and chest routes
• Once your run feels safe and your base is stable, prioritise stronghold cycles to increase diamonds per hour

Chests and random diamond drops

Chests are scattered around the world in structures such as houses, towers and dungeons. They can drop diamonds, but the chance is low. Think of chest diamonds as a bonus, not your main income.

The best way to use chests in your diamond plan is simple:

• Open every chest you see while you travel for other reasons
• Combine chest routes with flower collecting, quest paths and meteor locations

In other words, let chests add extra diamonds on top of everything else you are doing.

Badges and achievements

Badges reward you with diamonds the first time you earn them. The current system gives a certain number of diamonds based on the badge rating, which makes badges one of the best one time sources of free diamonds.

Common badge types include:

• Survival badges for reaching certain night counts or completing a full 99 days
• Progression badges for upgrading the campfire, building specific structures and successfully defending your base
• Exploration badges for collecting flowers, talking to the fairy, planting seeds and interacting with hidden objects
• Event badges tied to limited time events like meteor showers and special update challenges

Completed together, these badges can easily award more than a hundred diamonds in total. The exact total can change as new badges are added, but the principle stays the same. They are extremely valuable early on.

A fun example is the Humiliation badge. You earn it by dying to your own bear traps and it gives a small diamond reward. Easy tricks like this are worth mentioning because they are quick and memorable.

To get the most from badges:

• Check the badge wall or in game badge list and note which ones are still incomplete
• Focus on badges that fit naturally into normal gameplay, such as flowers and basic survival targets

Survival milestones at Day 50 and Day 99

On top of badge rewards, you also receive diamonds for hitting specific day milestones in a single run.

The key milestones are:

• Day 50 which rewards 2 diamonds
• Day 99 which rewards 3 diamonds when you complete the full 99 night cycle

These milestone diamonds stack with any badges you unlock at the same time, making long runs especially efficient. Aim for these once your classes and talents are strong enough to survive that long.

Daily quests and similar challenges

Depending on the current update, 99 Nights in the Forest may have a daily style quest board or mission system in the lobby. These quests usually:

• Ask you to complete simple tasks like collecting coins or clearing a stronghold
• Reward you with a small number of diamonds or useful items when you finish them

Daily quests are perfect if you log in most days. Even a few diamonds per day adds up quickly when added to strongholds and badges.

Meteor events and alien crabs

Meteor events are time limited events where meteors crash into the map and leave craters. Alien crabs often spawn around these craters.

During these events you can:

• Hunt alien crabs around meteor craters
• Complete related badges or hidden challenges that pay out diamonds or gem piles
• Gather meteor shards and special ores for later crafting steps

The exact numbers and rewards may change between updates. Treat meteor and crab content as high potential bonuses when they are active instead of something to rely on every week.

Obsidian chest and similar secret rewards

Some event chains use the meteor resources to unlock special items, one of the most talked about being an obsidian style chest.

In general, the pattern looks like this:

1. Break meteors and collect shards and ores
2. Convert or combine them through a crafting station
3. Use those resources to craft a special chest
4. Place the chest in your base and open it to trigger a hidden challenge and a large gem or diamond drop

Again, the exact design and rewards can change per event. When you see an event that involves meteor items and special chests, it is usually worth following the chain to the end, because the final drop is often generous.

Update parties and admin events

Sometimes the developers run update parties or admin events to celebrate big patches. During these, they may spawn diamonds and other rewards around the world.

These events:

• Can grant a lot of diamonds in a short time if you are online at the right moment
• Are not regular and are typically announced on the game page, social media or Discord

Because you cannot control when these happen, they should be viewed as bonus opportunities rather than a core farm. The smart approach is to follow the game’s official channels and try to be online around big update times.

Playing with friends for more diamonds

Almost every method in this guide becomes easier and more efficient with a small group:

• Stronghold runs are faster and safer with a coordinated team
• Long survival runs towards Day 50 and Day 99 are more realistic when people share roles like base building and damage
• Event tasks like meteor hunts and flower collecting can be split up so you cover more ground

If possible, play in a private lobby or with a consistent group of friends. This reduces random risk and lets you focus on efficient diamond farming.

How to keep your information fresh

Because 99 Nights in the Forest still receives updates, you should treat the details in this guide as a base. The best practice is:

• Always check fresh code lists before playing
• Assume event rewards like meteors and special chests may change from one patch to the next
• Revisit key numbers such as diamond rewards and badge counts after large updates

You can also check their official Discord.

Simple diamond farming plan

To make all of this practical, you can follow this simple routine:

1. At the start of a new campaign, redeem all current codes and use yay fishing during your first fishing trip
2. Work on easy badges and survival milestones while you learn the game
3. Once you can comfortably reach mid game, run the Cultist Stronghold whenever it is available
4. Pick up daily quests and take part in meteor or obsidian style events whenever you see them
5. Play with friends so you can safely reach long survival milestones and share event tasks

If you follow these steps consistently, your diamond balance will grow steadily without needing to spend Robux, and you will unlock classes and talents at a pace that keeps the game fun rather than frustrating.
