We often found in shopping malls that parents struggle to take care of their children. According to our survey, 85% of parents find it difficult to shop with their children in shopping malls. We think that the children’s lack of purpose makes them bored and do things that irritate their parents. We introduce a treasure hunting game to solve this problem. We conducted two field studies to design and test our game approach. Through the first study, we found that the game had success to give children a particular purpose, however, the game also can be an obstacle for shopping for parents. In response to this findings, we redesigned our game and conducted a second study to verify the new game design. The result of the second study revealed that the redesigned treasure hunting game allowed both parents and children to achieve their individual purposes.
