The object of the game is to describe how long it takes to do something. The way it works is that the 1st person says it takes 1 second to __________. The 2nd person says that it takes 2 seconds to __________, and so on.
Once 59 seconds is reached, the next person starts with 1 minute, progressing from there. It would look like this:
1 second 2 seconds 3 seconds ... 59 seconds 1 minute 2 minutes ... 59 minutes 1 hour ... 23 hours 1 day ... 6 days 1 week
Next person can start the game. Let me know what you think.
