A fair game gives each player the same chance of winning, whereas an unfair game gives some players a greater chance, even if short-term results appear balanced. In simple games involving equally likely outcomes, such as coins, number cubes, or spinners, the chances can be compared by listing or counting the outcomes that favor each player; formal probability calculations, expected value, and conditional or dependent events are not included.
A game is fair when every player has the same number of equally likely chances to win. It is unfair when one player has more chances to win.
To check a game:
Example: A spinner has 6 equal sections:
There are possible sections altogether.
Because Maya has more winning sections, she has a greater chance of winning. Therefore, this game is unfair to Leo.
A game can still have a close score for a short time, but it is fair only when the players have the same number of chances to win.
