What Are Gems in Defend Your Base From 67?

Gems are the main premium currency in the game. You use them to open crates (including the Galaxy Crate) and unlock upgrades, so having a steady supply keeps your roster growing. You earn them through gameplay rather than just waiting around, which means your farming strategy actually matters.

Fastest Gem Farming Method

The setup most players gravitate toward is built around income-first, then damage:

1. Drop Black Hole Generators early to build up your income in the first waves before you start spending on weapons.
2. Once your economy is running, add a strong damage tower, Lava Launcher is the go-to pick, though Elephant Turret is reportedly a cheaper alternative that may perform similarly.
3. Run the Lava Map on Hard Mode.

Hard Mode runs on Lava Map seem to be the sweet spot for gem output, players report getting somewhere around 10, 12 gems per run, with Lava Map edging out other Hard maps slightly. Those figures aren’t locked in, so your actual rewards may vary, but the ballpark seems consistent with what players are seeing.

If you’re new to the game and want to understand the maps and placement options better, the map guide is worth a look before you commit to a route.

Best Towers for the Gem Run

You don’t need a massive collection to run this efficiently. Here’s the rough setup:

Role	Tower	Notes
Income	Black Hole Generator	Place first, before any weapons
Damage (main)	Lava Launcher	Strong damage output
Damage (budget)	Elephant Turret	Cheaper option, likely comparable value

If you don’t have the Lava Launcher yet, the budget route uses Cactus Farm for income and Crossbow for damage. It’s a lighter setup and probably earns a bit less per run, but it’s a solid starting point while you build up your collection. Check the units page for unlock requirements once you know which towers you’re targeting.

Other Ways to Get Gems

Hard Mode farming isn’t the only source. A couple of other methods players mention:

• Season Pass missions, completing missions in the season pass can reward gems. The exact mission list changes with each season, so check the in-game season UI to see what’s currently available.
• Crates and one-time rewards, some progression milestones likely give a gem payout, though these aren’t repeatable farming routes.

There’s no active codes page at the moment, check the codes page in case any gem codes have been added since this was written.

Tips to Farm Gems Faster

• Prioritise income towers in the early waves. Rushing damage before your economy is set up costs you efficiency across the whole run.
• Hard Mode is worth it. The gem reward jump over lower difficulties seems meaningful enough to justify the difficulty.
• Run Lava Map specifically if you can. Other Hard maps appear to give slightly fewer gems per run based on what players have reported.
• Don’t skip the season pass. If missions are awarding gems, they’re essentially free currency for things you’d be doing anyway.
• Stack runs efficiently. Short Hard Mode runs back-to-back will out-earn longer casual sessions on easier difficulties.
