- Knowledge of The Game is the only thing required to play it.
- Thinking of The Game causes a player to lose.
- A losing player must announce the loss.
Different versions of the game exist, in which details are specified, such as allowing a short grace period (10-30 minutes) after losing to forget about the game again, at which point, they resume playing. Template:Citeneeded The Game has no end; players may lose repeatedly.
According to the Belgian newspaper De Morgen, the Game is played mainly in the United States and the United Kingdom, but also in Australia, Brazil, Japan, and Belgium. Despite its reported prevalence this is the only mainstream report of The Game.
