CookieRun: Crumble Release Date

Official Launch Date

Devsisters has confirmed that CookieRun: Crumble will launch globally on July 31, 2026. The game is an idle deck-building auto-battler set in the CookieRun universe, bringing together roster collection, team synergies, and hands-off combat progression. Launch day will be available on mobile platforms and PC, allowing players to sync progress across devices where supported.

The July 31 date marks the end of the pre-registration campaign, which runs for exactly one month beforehand. Players who pre-register before July 29 will retain access to milestone rewards earned during the signup period, including currencies, exclusive cosmetics, and potential early-access cookies tied to community goals.

Pre-Registration Window

Pre-registration for CookieRun: Crumble begins on June 29, 2026 and ends on July 29, 2026. During this window, players can register through the official website, App Store pre-order links, Google Play pre-registration, and PC launcher pages. Signing up is free and does not require spending money, though optional store pre-orders may offer additional platform-specific bonuses.

The pre-registration period also hosts three browser mini-games: Party Chemistry Lab, Crumble Boss Rush, and the Treasure Map Event. These mini-games contribute to global milestone counters and personal reward tracks. Completing mini-game objectives before July 29 ensures you claim everything before servers go live on July 31.

What Happens on Launch Day

When servers open on July 31, pre-registered accounts will receive bundled rewards directly into their in-game mail or inventory. New players who missed pre-registration can still download and play, but they will not receive retroactive milestone gifts tied to the signup campaign. Launch day typically includes a starter banner, tutorial chapters, and introductory events designed to onboard new Mercenary Guild members.

Expect possible maintenance windows and staggered regional rollouts even with a global date announcement. Devsisters historically soft-opens certain regions first during CookieRun titles. Monitor official social channels for exact server open times in your time zone, and prepare your team builds using our starter team guides before pulling on day-one gacha banners.
