A long-term operation game launched on the Meiyijia convenience store WeChat mini-program, designed to enhance user engagement and retention, as well as to assist in issuing and redeeming coupons during marketing campaigns. The game also helps understand user preferences for convenience store food items based on their behavior. The gameplay primarily follows the popular match-three style similar to "Sheep a Sheep," where players earn "Star Shells" as rewards by completing levels. These "Star Shells" can then be used to draw various prizes. The game not only offers fun and challenging gameplay but also integrates business goals like coupon issuance.
