Anthropologists Jean Lave and Etienne Wenger (1991) use the term “practice” to discuss how actions are situated in their socio-cultural contexts. Essentially, a practice is an activity that involves skills, resources, and tools, and is mediated by personal and cultural purposes.  One way to produce more meaningful educational games would be to design games in which players are engaged in richer, more meaningful practices.  A social game that different people interact with each other can help to inform a better understanding of cultural practice and social practice.  People can learn other cultures from playing game together. Besides, a social-practice game can help to cultivate problem-solving skills. In other words, people benefit from social game – being influenced by cultural practice and fostered a better team-oriented problem solving skills.
