Fastest Way to Get Gems in Defend Your Base From 67
Gems are one of the most important resources in Defend Your Base From 67. Players use them to unlock items, upgrades, and other useful features that help make progression much easier. Because of that, many players are always looking for the quickest method to farm gems without spending hours grinding normal matches.
One of the fastest farming strategies currently used by players focuses on defeating the 67 boss as quickly as possible. With the right setup and map choice, you can earn gems in just a few minutes per run. If you repeat the method several times, you can collect a large amount of gems in a short period.
Best Setup for Fast Gem Farming

To use this strategy effectively, you only need two main items:
- Black Hole Generator
- Lava Launcher
These two items work well together because the generator produces money quickly while the launcher deals strong area damage. If you don’t have these items yet, there are some alternatives you can try, such as:
- Cactus Farm
- Crossbow or other weapons
However, these alternatives are slower. The Lava Launcher setup is still the most reliable option for farming gems quickly. Some experienced players also recommend using the Elephant Turret, which can perform even better than the Lava Launcher. The problem is that it is harder to obtain, especially for free-to-play players.
Step-by-Step Fast Gem Method

Follow these steps to farm gems efficiently.
1. Start a Solo Game
First, enter the Lava Map on Hard Mode and make sure you are the only player in the lobby. Playing solo makes the boss easier to control and keeps the strategy consistent.
2. Choose the Closest Base
When the game starts, select the base that is closest to the 67 boss spawn. This reduces travel distance and helps your weapons hit the boss earlier.
3. Fill Your Base With Black Hole Generators
At the start of the match, do not place weapons yet. Instead, spend all your starting money on Black Hole Generators. Fill your entire base with them so you can build cash quickly during the first waves. The boss usually won’t destroy your door immediately during the early waves, so you have time to generate money.
4. Save Around 20,000 Cash
Wait until you reach around 20,000 money from the generators. Once you reach this amount, you can start building your main damage setup.
5. Place Lava Launchers
Place about 6 Lava Launchers around your base. Sometimes six is enough to defeat the boss, but if the damage feels too low you can:
- Sell some generators
- Upgrade your launchers
- Place additional launchers if needed
Upgrading even one or two launchers can greatly increase your damage and range.
6. Defeat the Boss Quickly
Once everything is upgraded, the boss’s health should drop very quickly. In most runs, the boss will retreat or be defeated in about 2 minutes and 30 seconds. Each successful run gives around 12 gems. With practice, some players have managed to finish runs in around 90 seconds, making the farming method even faster.
Alternative Method Using Elephant Turret

If you have access to the Elephant Turret, it can sometimes perform even better than the Lava Launcher. Advantages include:
- Cheaper upgrades
- Larger attack range
- Stronger damage
In some tests, using several Elephant Turrets allowed the boss to be defeated just as fast or slightly faster than the Lava Launcher strategy.
Extra Way to Get More Gems
Besides farming the boss, you should also check the Season Pass missions regularly. Completing missions allows you to:
- Level up the pass
- Claim additional gem rewards
This is a great way to gain extra gems while playing normally.
Farming gems in Defend Your Base From 67 becomes much easier once you know the right strategy. By combining Black Hole Generators with strong weapons like the Lava Launcher, you can defeat the 67 boss in just a few minutes and earn gems very quickly. After repeating this method several times, you can build up a large gem supply without spending real money. As you unlock stronger weapons like the Elephant Turret, the runs can become even faster, allowing you to farm gems more efficiently with every attempt.
