Video Guide
Why Linking Still Matters After Launch
Crumble launched July 30, 2026, but crossover and pre-registration mail still need to be claimed before August 29, 2026 (11:59 PM GMT+9). Missed mail is not reissued. If you linked CookieRun: Kingdom or CookieRun: OvenBreak on the pre-registration site, confirm those bundles landed in-game.
Separate from franchise linking: bind a Google account (mobile ↔ Google Play Games PC) and keep your DevPlay MID handy for coupon redemption.
Kingdom and OvenBreak Crossover Bundles
Players who linked Kingdom or OvenBreak player IDs on the pre-registration site were promised crossover packages. Kingdom link: 1,000 Crystals, 1,000 Choco Chalk, 1,000 Rainbow Cubes, and 100,000 Coins. OvenBreak link: 1,000 Crystals, 1,000 Rainbow Cubes, 3,000 Magic Powder, and 100,000 Coins.
Full milestone tables live on pre-registration rewards. If mail is missing, verify you used the same ID family that completed pre-registration, then check the in-game mailbox filters before contacting DevPlay support.
DevPlay MID and Coupons
Gift codes redeem through Settings → User info → Register Coupon (or the DevPlay coupon portal) with your MID. As of August 2, 2026, COOKIERUNCRUMBLENO1 is confirmed on our codes page—ignore third-party generators.
Never share your MID or password in Discord “claim bots.” Official flows stay inside the client or coupon.devplay.com.
Cross-Platform Progress
Google Play Games PC and Android share progress when signed into the same Google account. Apple ID players should follow in-client account bind prompts before switching devices. Do not create a second guest clear if you already started claiming the 7-day Cream Soda login on another install.
Platform install steps: download and platforms.
Claim Checklist Before August 29
Open Crumble daily through August 29 to empty pre-registration, crossover, and event mail. Keep the 7-day Cream Soda and 30-day attendance streaks alive—linking does not auto-claim login calendars.
Spend crossover crystals intentionally: fund core upgrades and documented banner plans from launch banner and gacha priority, not impulse Alternative cosmetics.
- Confirm Kingdom / OvenBreak crossover mail
- Claim pre-registration milestone packages
- Bind Google / Apple / DevPlay accounts
- Save MID for future coupons
- Continue Cream Soda + attendance logins
Frequently Asked Questions
Can I still link Kingdom after launch?
Pre-registration linking was campaign-gated. If you already linked, claim mail before August 29. New post-launch link windows will be announced officially if they open.
Do I get both Kingdom and OvenBreak packages?
Each linked title grants its listed bundle when the campaign rules allowed dual linking—check your mailbox for both entries.
What is a DevPlay MID?
Your DevPlay member ID used for coupon redemption and account support. Find it under User info in Settings.
Are guest accounts safe?
Bind a platform account ASAP. Guest wipes risk losing login streaks and unclaimed mail.
Where is the full reward table?
On the pre-registration rewards page, including Pick-up cutters from the 2M pre-reg track.
