Seven Knights Idle Adventure: How to Redeem Codes (May 2026)

You opened this guide because you want working Seven Knights Idle Adventure codes and the exact steps to redeem them, not a wall of “maybe still active” guesses. Here is the clean version: which codes are live in May 2026, what each one actually gives, and where to type them in.

The short version

• Redeem PD2NDSPECIAL first. It is the heaviest current code: Goddess’ Gift x1, Free Rubies x100,000, and 77x Event Summon Ticket x100.
• Then SKIAASCEND2 (Legendary Hero Selection Ticket x2) and SKIA3NMARE (Elixir x3,000).
• Also live in May 2026: 2NDSKIABIRTHDAY1 and 2NDANNIVERSARY4.
• In-game path: Menu (four-square icon) → Settings (gear) → Account → Redeem Code. Rewards land in your in-game mailbox.
• On iOS or web, redeem at coupon.netmarble.com/skiagb using your Member Code (PID).

Active codes for May 2026

These five are confirmed active in the May 2026 code list. Codes are case-sensitive and one-time per account, so paste them exactly as written, in all caps, with no extra spaces.

• PD2NDSPECIAL – Goddess’ Gift x1, Free Rubies x100,000, 77x Event Summon Ticket x100. Enter this one first: it stacks premium currency with summon tickets, so it moves your account further than any other current code.
• SKIAASCEND2 – Legendary Hero Selection Ticket x2. Targeted progression instead of random pulls, which makes it unusually efficient for fixing a specific team gap.
• SKIA3NMARE – Elixir x3,000. A solid resource boost for pushing through progression walls.
• 2NDSKIABIRTHDAY1 – Anniversary/birthday campaign code. Redeem it early; event-tagged codes turn over fast.
• 2NDANNIVERSARY4 – The other anniversary-wave code in the May rotation. Same logic: claim it before the campaign window closes.

Rewards in this game swing hard between a small consumable stack and a genuine account jump, so the order above matters. Spend your first redemptions on rubies, summon tickets, and the legendary selection ticket before anything else.

Older codes still worth trying

These older codes still show up in current code roundups and may remain valid on some accounts. They cost nothing to test after the priority set, but treat them as bonus rather than guaranteed:

• SKIA5HIGHLORD
• SKIADDAY6
• SKIA2026LUNARNY
• SKIARUNCANDEL
• SKIAMONPEC6819
• SKIAMONHPK7601
• SKIAMONWEBTOON
• SKIAMONORV2
• SKIADEMONKING

The seasonal codes SKIA2026LUNARNY and SKIARUNCANDEL were in active rotation in the March 2026 roundup, which is why they belong in the “try it” tier rather than the dead pile. Four more documented codes round out the list: SKIAMONSHKY0785, 7TRICKORTREAT7, IAMGUILTY, and UZZUZZU. Test these last, since their reward text is less clearly documented than the active set above.

How to redeem Seven Knights Idle Adventure codes

There are two redemption routes. The in-game menu is fastest on Android; the web page is the reliable fallback on iOS and PC.

In-game:

• Tap the Menu button (the four-square icon).
• Open Settings (the gear icon), then go to Account.
• Select Redeem Code (also labeled Coupon), enter the code, and confirm.
• Open your in-game mailbox to claim the reward package.

Web (iOS / PC):

• Go to the official Netmarble coupon page at coupon.netmarble.com/skiagb.
• Enter your Member Code (PID) and the coupon code, then submit.
• Rewards are delivered to your in-game mailbox, so open the game and claim them there.

Redeem one code at a time and check the mailbox after each. That way you can tell immediately whether a code posted, was delayed, or had already been used on your account. If a reward does not appear right away, relog once before assuming the code failed.

Which rewards to prioritize

When several codes are about to expire and you can only chase a few, use the reward type as the tiebreaker:

• Free Rubies – The best general-purpose reward. They feed premium pulls and have the broadest account value.
• Event Summon Tickets – Strongest during active banners, since they convert straight into roster progress without spending rubies.
• Legendary Hero Selection Tickets – High value because they remove randomness and let you fill an exact team gap.
• Elixir and resource packs – Useful for progression walls, but a tier below premium currency and summon access.

That ranking is exactly why PD2NDSPECIAL is the standout code in the current wave: rubies plus 77 summon tickets in one redemption can reshape your short-term summoning plan. SKIAASCEND2 grades next because a targeted legendary selection is far rarer than generic consumables.

Common mistakes

• Typing codes in lowercase. Codes are case-sensitive. Paste them in all caps with no leading or trailing spaces.
• Blasting the whole list at once. Redeem one code, check the mailbox, then move on, so you always know what landed.
• “Invalid code.” Usually expiry, a typo, or a region/client mismatch. Re-paste in uppercase before giving up.
• “Already used.” These coupons are one-time per account. If you claimed it before, there is no second reward.
• No reward in mail. Wait, relog once, then recheck the mailbox before declaring the code dead.
• No coupon field in-game. Switch to the web page at coupon.netmarble.com/skiagb and redeem with your Member Code (PID).

Practical takeaway

Redeem PD2NDSPECIAL first for rubies and 77 summon tickets, then SKIAASCEND2 and SKIA3NMARE, then the two anniversary codes. Use the in-game Menu → Settings → Account → Redeem Code path, or coupon.netmarble.com/skiagb on iOS and PC, and claim everything from your mailbox. Code rewards in Seven Knights Idle Adventure are time-sensitive progression, so treat the high-value active codes as a priority, not background housekeeping.
