Passage: Losses must be announced. This can be verbally, with a phrase such as "I just lost The Game", or in any other way: for example, via Facebook. Some people may have ways to remind others of The Game.The definition of "thinking about The Game" is not always clear. If one discusses The Game without realizing that they have lost, this may or may not constitute a loss. If someone says "What is The Game?" before understanding the rules, whether they have lost is up for interpretation. According to some interpretations, one does not lose when someone else announces their loss, although the second rule implies that one loses regardless of what made them think about The Game. After a player has announced a loss, or after one thinks of The Game, some variants allow for a grace period between three seconds to thirty minutes to forget about the game, during which the player cannot lose the game again.The common rules do not define a point at which The Game ends. However, some players state that The Game ends when the Prime Minister of the United Kingdom announces on television that "The Game is up."
