Fairness means reasonability and equity that is unbiased. Therefore, it is the main notion of justice supposing legitimacy that implies righteousness. In sport events, fairness matters because it is directly associated with a fair game. If a sport game is not fairly played, it should be the model of biasness in game environment and also artificial injustice. Accordingly, to play a fair game, the rules, norms, and systems should be fair, and equality should be maintained. In other words, in sport events, equality is a condition to play a fair game. The outer environment, for example, climate conditions, and also, artificial conditions like the stadium should be fairly given. Also, unfairness to impose inequality of opportunity on competitors should never be practiced. Accordingly, this thesis is going to suggest conditions for equality to play a fair sport game and also aggressively identify unequal treatments on competitors. In other words, this study will highly stress equality in sport games and also morality on games and players as voluntary participants. The orientation and purpose of this study is also on the point that in competitions, players should be treated as voluntary as well as ethical competitors.
