Seven Knights Re:Birth just handed its player base a stack of free currency and summon vouchers, and the timing lines up with the game's first anniversary celebration. Four new codes dropped recently, each delivering a different type of reward, and a handful of summer event codes are still active alongside them. The window to claim these won't stay open forever, so the sooner you get to the redemption screen, the better.

Every active code and what it pays out
Here's the full breakdown of what's currently working in Seven Knights Re:Birth:
The key here is NEWKARLHERON, which delivers 10 Rate Up Hero Summon Vouchers targeted at the current banner. That's the most immediately valuable pull currency in the batch if you're chasing Clemyth or Dellons, the two newest characters added to the roster. SKRE300BIRTH is the other standout, offering a combined haul that includes 300 Hero Summon Vouchers alongside a Legendary Accessory Selection Box.
How the anniversary context changes things
The four codes tagged with anniversary branding (NEWKARLHERON, 1STANNIVERSARY, THXUSENA, SENA1STANNIV) all arrived together as part of the first-anniversary push. This kind of multi-code drop is more generous than the typical single-code event release, and it suggests Netmarble is leaning into retention for the milestone period.
What most players miss is that codes expire on different schedules, and some go dark without advance warning. The summer codes (SUMMERTIME7K, 7KSUMMERFEST, 7KSUMMERRUBY) have been live for a while now and could rotate out as the seasonal event wraps. SKRE300BIRTH has been active since a March maintenance window and has no listed end date, but that status can change with any major update.
One community note worth flagging: a user comment suggests the four anniversary codes may have already expired for some accounts. If any of the new codes return an error, it's worth trying the others before assuming the batch is fully dead. The summer codes appear to still be active independently.
Redeeming and collecting your rewards
The redemption flow is straightforward for Android and PC players. Open the settings gear icon, navigate to Account, and tap the Coupon button. Paste the code, confirm, then check your in-game Mailbox to collect. Rewards in the Mailbox have their own expiration timers, so don't let them sit.
For iOS, copy your UID from the same Account screen, then complete the full process on the Netmarble coupon website. Each code is single-use per account, so there's no benefit to entering the same code twice.
With the 6/25 update arriving this week and new characters like Orca joining the lineup, the free summon vouchers from these codes feed directly into the current pull economy.
