Devsisters is not slowing down. The studio behind the wildly popular CookieRun franchise has opened global pre-registration for CookieRun: Crumble, a lighthearted deck-building idle RPG heading to mobile and PC in July 2026. Sign-ups went live on both the App Store and Google Play on June 29, and the game’s store listing points to a July 31 launch, though Devsisters has not locked in the exact date just yet.

First teased as “Project CC” back in February and formally unveiled at Devsisters’ DevNow 2026 showcase, Crumble trades the endless-runner roots of the series for an auto-battler built around collecting Cookies, assembling teams and leaning on strategy rather than reflexes. The hook is a charming one: you follow a band of underqualified, down-on-their-luck Cookies squaring off against alternate-universe versions of familiar CookieRun characters.
Idle progression with a deck-building twist
As an idle RPG, Crumble is designed to keep earning for you whether you are actively tapping or away from the app, while the deck-building layer rewards players who enjoy experimenting with team compositions and synergies across its various game modes. It is a comfortable fit for the pick-up-and-play rhythms of the platform, but with enough depth for theorycrafters who like to min-max their rosters.
Devsisters is sweetening the pre-launch period with a stack of activities. A Party Chemistry Lab lets you build a Cookie team and get matched to a suggested playstyle, then throws that squad into a short Crumble Boss Rush mini-game. A separate Treasure Map event has players solving clues and completing quests to piece together a map and unlock rewards ahead of release.
Pre-registration rewards
Registering pays off in two directions. Signing up on both the website and the app store grants a bundle for the existing CookieRun: Kingdom – including 1,000 Crystals, 1,000 Choco Chalk, 1,000 Rainbow Cubes and 100,000 Coins – while global milestone targets unlock Crystals, Coins and Premium Cookie Cutters for Crumble itself as more players join. There are also random-draw giveaways for CookieRun-themed merchandise.
CookieRun: Crumble is set to launch globally in July 2026 on Android, iOS and PC via Google Play Games. If you are already deep in the CookieRun universe – or just looking for a breezy new idle RPG to fold into your rotation – pre-registration is open now.
