It is very important to understand the difference between sports and games as some might misunderstand the two terms as same. The first thing one must do is to find the terms as two different words as people might be misled by the terms as synonyms. Games test skills of person as an individual while on the other hand sports tests skills and performance.
Sports is considered activity which needs physical ability and some mental skill as it is played with the sense of competition. Several skills of sportsperson are tested in sports and not in games.
Games are considered usually team activities as individual talent does not decide the achievement of goal. We can not deny the fact that sports and games are played for gratification and enjoyment as both need spirit among the players. In a game an individual participant as considered as player while in sports he or she is referred as sportsperson or athlete. In sports, mental strength is put to test in game while in sports physical energy is put to test.
Therefore, we are left with dissimilarity so acceptable that few of us can observe it!
