Release and platforms
- Global launch: 30 July 2026.
- Pre-registration window: 29 June to 29 July 2026.
- Platforms: iOS (App Store), Android (Google Play), PC (Google Play Games), plus Galaxy Store and ONE store.
- Free to play with optional purchases.
How to pre-register
- Sign up on the official site at pre.cookieruncrumble.com to join the pre-launch event.
- Also register on your store of choice (Google Play, App Store, Galaxy Store or ONE store).
- Doing both enters you into the merchandise raffle (figures, desk mats, stress balls).
Rewards and mini-games
Every sign-up counts toward global milestone rewards paid out at launch: Crystals, Coins, Premium Cookie Cutters and Premium Pet Tickets. Three browser mini-games feed the campaign:
- Party Chemistry Lab: a quick team-building quiz that matches your party to a playstyle and carries into Boss Rush.
- Crumble Boss Rush: battle bosses and collect Crumbs for ranks (Rank IV any, III at 10,000, II at 30,000, I at 80,000).
- Treasure Map: solve steps to unlock map pieces, hidden rewards and secret codes. See the Treasure Hunt Answers guide for the clues people have already worked out.
What lands in your mailbox
Devsisters has named the reward types without committing to quantities, so treat the amounts as unconfirmed until the mail actually arrives. Expect a mix of the following:
- Cookie summon tickets and Premium Cookie Cutters, which are what you pull new Cookies with.
- Pet summon tickets for the companion units.
- Crystals and Coins, the premium and everyday currencies.
- Extra pulls on the launch pickup banner, on top of the general summon pool.
The practical takeaway is that you will start with a real handful of summons rather than one or two, which is why a light reroll is viable and why it is worth deciding your targets before you tap anything.
