Seven Knights Idle Adventure Codes: Active and Expired (June 2026)
Last checked June 21, 2026 (UTC)
Netmarble drops Seven Knights Idle Adventure codes around updates and milestone events, and I keep the working coupons gathered here. We refresh the list whenever new ones land.
Seven Knights Idle Adventure codes are the alphanumeric strings Netmarble posts on the official Seven Knights Idle Adventure channels and during update livestreams for free Rubies, Summon Tickets, Gold, Hero EXP, and equipment materials. Rubies are the premium currency for the gacha that recruits new Heroes. Summon Tickets pull straight away without touching your Rubies. Gold and Hero EXP feed the idle progression that levels your roster while you're offline, so the code freebies stack on top of what you're already banking by doing nothing.
Quick tip. save your code Rubies and Summon Tickets for the limited and rate-up Hero banners rather than the standard pool. Because the game is idle, you pile up base resources over time anyway, so the gacha currency is best spent when a meta-defining Hero gets boosted odds.
Seven Knights Idle Adventure codes show up during major updates, anniversary events, and Netmarble milestone campaigns. They run on the usual gacha redemption timeline. You redeem in-game through the settings menu, or on the Netmarble coupon page with your account, and they're case sensitive.

Seven Knights Idle Adventure codes FAQ
What are Rubies used for?
Rubies are the premium currency for the gacha that recruits new Heroes. They're the gate on expanding your roster, so any code drop with Rubies is the most valuable one for collection-focused players like me.
Should I save for rate-up Hero banners?
Yes. Since the game is idle, you stockpile base resources over time while you're offline. The gacha currency (Rubies and Summon Tickets) is the real bottleneck, so spend it when a meta-defining Hero gets boosted odds on a rate-up banner.
Is this the same as the original Seven Knights?
No. Seven Knights Idle Adventure is an idle RPG spinoff of the original Seven Knights franchise. It shares characters and lore but runs as its own game with a separate account, progression, and code system.
Why does my code keep failing?
Three usual causes: it expired, you already used it on this account, or you slipped on the capitalization. Seven Knights Idle Adventure codes are case sensitive, so use the Copy button to keep the exact form.
Do codes work on the coupon page and in-game?
Most codes work through both paths on the same account. If the in-game option is missing in your build, use the Netmarble coupon page with your Member Code. The rewards land in the same in-game mailbox either way.
How long do mailbox rewards stay claimable?
Fourteen days for most code rewards. Open your in-game mailbox and claim everything before the timer runs out, especially the Rubies, since you'll want those for the current banner.
