Every way to earn gems in Command An Army ranked, and the smartest places to spend them once you have them.

Quick Answer: How Do You Get Gems in Command An Army?

Gems are the unlock currency, and the fastest 2,500 you will ever earn are already free: redeem the three working codes on our codes page (1MVISITS, RELEASE and credits) before anything else. After that the recurring sources are quests, playtime rewards and milestone drops — steady, not explosive. Spend them on unlocking units first and upgrades second, and always keep a small reserve for new-unit releases.

💡 Redeem the codes before your first attack — early Gems buy early roster slots, which compounds through every later wave.

Gem Sources, Ranked by Priority

Not all sources deserve equal effort. One-time sources pay instantly and should be emptied today; repeatable sources are where your long-term income lives. This is the priority order we follow:

Gem Sources, Ranked by Priority
Source	Type	Effort	Priority
Codes (1MVISITS, RELEASE, credits)	One-time	Under a minute	Do first — up to 2,500 Gems
Milestone codes (e.g. 1M visits)	One-time, event-based	Watch Discord/Group	Redeem the day they drop
Quests	Repeatable	Active play	Main steady income
Playtime rewards	Repeatable	Passive — just stay in game	Background income, always on

💡 Joining the official Roblox Group unlocks Auto Attack, which keeps your army fighting — and playtime rewards ticking — while you step away.

What to Spend Gems On (Priority Order)

Every Gem spent on a unit that covers a missing role returns value every single wave; Gems spent on marginal upgrades return value only in the fights you already win. That asymmetry sets the spending order:

First: unlock your core roles — a front-line tank, a healer, then a second damage dealer. The summon page covers which units to target.
Second: firepower upgrades on units you field every wave — your bread-and-butter army compounds fastest.
Third: new-unit summons after updates, so a fresh meta unit does not catch you Gem-broke.
Skip: cosmetic and convenience buys while your core formation still has gaps.

The Daily Gem Loop

Gems reward presence. A short daily session covers everything: log in, let playtime rewards accrue, clear the day's quests, launch your attacks — the army keeps attacking even while you are offline — and re-check the code channels before logging off. Players who run this loop for a week out-earn players who grind a single long session, because the passive sources never sleep.

💡 New codes cluster around milestones and updates — the update log page tracks both, so a thirty-second check tells you whether today has free Gems waiting.
