The Latest Admin Abuse Update (running through July 2026) added the two currently working redeem codes: admin abuse today and roll. admin abuse today grants 3,000,000 Coins and 35,000 Brains; roll grants 100,000 Coins, 250 Brains, plus a 1x Luck Boost and 1x Roll Boost.
Both codes have been confirmed active and verified for the July 2026 window. Redeem them in-game from the Codes button in the lobby before the event ends.
During the event itself, drop rates for higher-tier units have been reported as temporarily boosted. Treat this as an unofficial report; verify any specific drop-rate claim inside the lobby before committing a long rolling session.
