How to get gems

Gems are the quote currency for trades. You earn them by playing and by selling units you do not want. Codes are not a method in 2026.

Titan Tactic's verified video promises a large gem day. I treat the title as a creator challenge, not as a rate you should expect. The wiki describes these methods: clear modes that pay, then sell duplicate units into the market instead of hoarding every summon.

Story clears and the repeatable queues (Endless, Raid, Abysmal) are the legal farms. Raid tickets are a separate currency that buys the raid crate. Do not convert "tickets" into "gems" in your head. They spend in different shops. The raid page keeps that split.

Selling is the other half. A basic or rare duplicate is often worth more as a gem credit than as a fourth copy on your pad. Check the value list before you vendor a mythic by habit. Upgraded Titan Cameraman at 15,000 gems on all three lists is not a unit you delete because a loading screen called it old.

The 2023 coin codes are not gem codes, and they do not work. Anyone selling a "gem code" in 2026 is describing a product this game does not have. See the codes page.

I will not publish a gems-per-hour figure. No two sources I opened printed the same hourly rate, and a rate from a private server boost would be a different game than a public lobby.

Questions people ask

What is the fastest way to get gems?

Play a mode you can finish, sell duplicates, and do not chase reseller sites. I am not quoting an hourly number.

Do codes give gems?

The old codes paid coins and boosts in 2023. The box is gone, and those rewards were not a modern gem printer.
