On April 18, 2026, users of the CashWalk rewards app participated in the daily “Money-Making Quiz” event, which offered small incentives for correctly answering brand-related questions. Among the featured quizzes was one centered on Soylab’s Black Soybean Milk product, prompting users to identify a descriptive phrase based on a Hangul initial clue: ㅈㅎㄷㅇ. According to multiple Korean media reports published that morning, the correct answer to the quiz was “진한두유,” translating to “rich soy milk” in English.
The quiz appeared as part of a promotional campaign highlighting Soylab’s low-sugar black soybean milk, which was advertised as having 96% raw soy milk content and being made by finely grinding whole soybeans. The promotion emphasized reduced sugar and calorie content whereas maintaining a satisfying texture, with a special discount price of 464 won per pack available until April 19, 2026. These details were consistently reported across regional Korean news outlets covering the CashWalk quiz event.
In addition to the Soylab quiz, the same day’s CashWalk event included a separate question related to Baedal Minjok (Baemin), Korea’s popular food delivery platform. That quiz asked users to complete the phrase “Baedal Minjok OOOO에서는 처갓집양념치킨, 네네치킨, 멕시카나 등 10개 이상의 브랜드 할인 쿠폰을 드려요,” with a hint of the initial consonants ㅂㅉㅎㅇ. The verified answer was “배짱할인,” while an alternate acceptable response listed in some reports was “네네, 처갓집,” referencing two of the chicken brands featured in the promotion.
Another quiz in the rotation concerned the National Health Insurance Service’s primary care chronic disease management program. Users were asked to identify the type of management provided at local clinics for hypertension and diabetes, with a hint of ㅊㄱㅈㅇ. The confirmed answer was “체계적인,” meaning “systematic,” with additional accepted answers including references to the public corporation, condition names, and program structure.
These quizzes exemplify the growing trend of reward-based engagement in South Korea’s mobile app economy, where users receive small monetary or point-based rewards for interacting with advertisements and promotional content. Platforms like CashWalk partner with brands to increase visibility and consumer interaction through gamified experiences, particularly around time-limited offers and product launches.
While the financial value of individual quiz rewards is typically modest, the cumulative effect contributes to user retention and brand awareness for participating companies. The Soylab promotion, in particular, aligned with broader consumer interest in healthier beverage alternatives, combining nutritional messaging with time-sensitive pricing to drive engagement.
As of the publication date, no official statements from Soylab, Baedal Minjok, or the National Health Insurance Service were publicly available regarding their specific involvement in the CashWalk quiz campaigns. The information presented is based solely on the quiz content and answers as reported by Korean news outlets monitoring the event on April 18, 2026.
