Tactics

Description

Play or entertainment

Participants could choose to play alone or join a mulit-player session to compete with others. There was also a leader board, which dynamically ranked participants’ achievements against peers.

Challenge

The question pool included 1,000 questions under five themes: ‘Food rumors’, ‘Internet famous food’, ‘Knowledge about tea’, ‘Staying away from junk food’, and ‘Healthy eating for families’. There was a good mix of common-sense questions and difficult ones. The questions were randomly selected at each round of participation. Participants could repeat the quiz-game as many times as they wanted.

Real-time feedback

Participants received feedback after answering each question: they saw a pop-up box briefly explaining the related food safety fact, and the percentage of other players who got the question correct. This allows participants to address their knowledge gaps or misperceptions immediately.

Reward

Each round of participation resulted in an opportunity to win a prize (e.g. points on Alipay, cash, or payment-in-kind, etc). As users accrued points or ‘leveled up’, their chances of winning a prize increased.
