A game consists of two or more players and a set of rules that generally define how the game is won or lost.
As a result, for a game to exist, it needs the following:
- A set of rules to define: 1) winning 2) losing and 3) how to play the game.
- People who are willing to play the game.
- Rules can be optional or mandatory.
- Punishment (perceived or real) for not following the rules.
