How to Pre Register Cookie Run: Crumble — All Platforms

This page is the record of how Cookie Run: Crumble pre-registration worked. The window opened June 29 and closed with the global launch on July 30, 2026 — you can no longer sign up. If you did, there is still one thing left to do; see the claim deadline below.

Step 1 — Register on the official website

Players went to the official CookieRun: Crumble pre-registration site (pre.cookieruncrumble.com) and signed up there. Website registration automatically enrolled you in the pre-launch event — no extra forms or steps beyond the sign-up itself.

Step 2 — Register on your app store

Then they pre-registered on the storefront they would actually play on:

• Google Play — Android, and also PC via Google Play Games (Devsisters has officially confirmed the game for mobile and PC)
• Apple App Store — iOS
• Galaxy Store — Samsung devices
• ONE store — Korea

Doing both steps mattered: players registered on the website and a store were entered into the merchandise raffle (Pure Vanilla Cookie figures, desk mats and stress balls — 75 prizes in total, one win per person).

Step 3 — Play the browser mini-games

The pre-registration site hosts three mini-games with their own rewards:

• Party Chemistry Lab — build a Cookie party and get a matched playstyle suggestion. The team you assemble carries into the next game.
• Crumble Boss Rush — a short browser boss fight. Tap bosses and collect Crumbs to climb ranks: Rank IV for any participation, Rank III at 10,000 Crumbs, Rank II at 30,000, and Rank I at 80,000. Rewards are granted by rank; the exact contents per rank are to be confirmed at launch.
• Treasure Map Event — solve clues and complete missions to collect map pieces, unlocking hidden rewards and secret codes. Keep any codes you find — Devsisters games typically redeem codes on a web coupon page tied to your DevPlay account, and our codes page will track Crumble’s once it’s live.

Why pre-registering is worth it

Every sign-up counts toward global milestone rewards — Crystals, Coins, Premium Cookie Cutters and Premium Pet Tickets delivered to everyone at launch. The full tier table, social-media milestones and the Kingdom/OvenBreak cross-game bonus are covered in our pre-registration rewards breakdown.

Those free Crystals fund your first summons, so skim the reroll guide and the beginner guide to hit the ground running.

Don’t forget the claim deadline

Launch rewards arrive in your in-game mailbox after release — but they must be claimed by August 29, 2026, 11:59 PM (GMT+9) or they’re forfeited. Log in, open your mail, and bank everything — this is the only step left over from pre-registration.
