Cookie Run: Crumble Codes (August 2026)

Cookie Run: Crumble is Devsisters’ idle RPG spin on the Cookie Run franchise, where your squad of Cookies battles waves of Crumbles for Coins, XP, and gear. Coupon codes hand out extra Crystals, Rune Crystals, and other login-boosting items without any grinding required.

Two codes are currently redeemable. Enter them exactly as shown, since coupon codes are case-sensitive and each one can only be claimed once per account.

Codes for Cookie Run: Crumble are claimed through a web coupon page rather than an in-game text box, so you’ll need your account’s MID handy before you start.

Open Cookie Run: Crumble on your device and play until the menu button becomes available on screen.

Tap the menu button, then select the cogwheel (settings) icon.

Open the Account tab, log in with your DevPlay ID if you haven’t already, and copy the MID listed there. This is your account identifier and it’s required to claim rewards.

Go to the Cookie Run: Crumble coupon page on a browser.

Paste your MID into the first textbox, then type the code into the Coupon Code textbox.

Tap Claim Reward. Rewards are delivered straight to your in-game mailbox, so open the mail icon in Cookie Run: Crumble to confirm the items landed.

Where to find new codes

Devsisters tends to drop fresh coupons around launch milestones and events rather than on a fixed schedule. The Cookie Run: Crumble Discord server is the most reliable place to catch new codes as soon as they go live, and the game’s YouTube channel and X account also post announcements when rewards are added.

Bookmark this page and check back regularly. As soon as a new coupon is confirmed working, it gets added to the list above.
