Chips Ahoy! is challenging cookie lovers to solve a mystery flavor and win big — one lucky winner takes home $25,000, and 50 runners-up score cookies and branded swag. The sweepstakes runs through Halloween with multiple entry methods (guess the flavor daily, opt into emails once, or mail in), and no purchase required. With 51 total prizes and daily entry options, this is one worth adding to your late-summer rotation.
What Is The 2026 Chips Ahoy! Halloween Mystery Flavor Sweepstakes?
This sweepstakes is built around Chips Ahoy!’s launch of a mystery-flavored cookie for Halloween 2026 — the puzzle angle makes it more engaging than a standard brand giveaway. Entrants can taste the mystery cookie (optional purchase, not required), guess the flavor online, and rack up daily entries for a shot at the grand prize. It’s best suited for snack lovers, Chips Ahoy! fans, and anyone who enjoys the fun of a flavor-guessing game alongside legitimate cash and prize chances.
Mondelēz (the parent company behind Chips Ahoy!) runs polished, legitimate sweepstakes, and with 51 total winners, the odds here are solid compared to single-prize giveaways.

- Full official rules: https://mondelez.promo.eprize.com/camystery26/public/fulfillment/rules.pdf
Entry Method 1 – Email Marketing Opt-In: Register at chipsahoymystery.com and opt into sponsor emails to receive one entry. Limit of one per person for the entire Promotion Period.
Entry Method 2 – Guess the Mystery Flavor Online: Visit chipsahoymystery.com, submit your guess of what the mystery flavor is (your guess does not need to be correct), and earn one entry. Limit of one entry per day per person for the entire Promotion Period.
Entry Method 3 – Mail-In Entry: Hand-write your name, address, phone number, email, and birthdate on paper and mail to the address provided in the official rules. Mail-in entries must be received by November 9, 2026. Limit of one per person for the entire Promotion Period.
Optional Purchase: You may purchase a specially marked Limited Edition box to taste the mystery flavor before guessing, but no purchase or tasting is required to enter, and a purchase will not increase your chances of winning.

Is This Sweepstakes Worth Entering? (Quick Take)
Yes — this is worth entering, especially if you enjoy the game element of guessing a mystery flavor. The $25,000 grand prize is substantial, and the 50 secondary prizes add real value to your odds. Since daily online entry is allowed through Halloween, consistent daily submissions cost you nothing and meaningfully increase your total chances. The mail-in and email opt-in methods give you bonus one-time entries if you want to maximize your entry count. Even if the mystery flavor guessing game isn’t your thing, the prize potential alone makes it worth at least a couple of online entries.
Pro Tips to Increase Your Chances
- Enter daily by guessing the mystery flavor at chipsahoymystery.com — you get one free entry per person per day through October 31, so submit a guess every day to accumulate as many entries as possible
- Use the email opt-in method to add one more entry to your total (limit one for the entire promotion)
- Mail in a paper entry for an additional one-time entry — must be received by November 9, so send it early if you choose this route
- No purchase is required, but if you’re curious about the flavor, a specially marked box is available at retailers (though purchasing won’t boost your odds)
- Confirm you meet the age requirements for your state (18+ for most, 19+ for Alabama/Nebraska, 21+ for Puerto Rico) before entering
- Register with a valid email you check regularly, since winners are notified via email
