“Insomnia: The Game of Absurd Sleep Patterns”
The board itself would be fairly normal, with cards, squares, a path and so on. Each player could only take their turn, however, when everyone is is asleep. If two players are ever in the same room with the board, they both forfeit their turn. Thus, the object is to figure out everyone else’s sleep patterns and make your own as unpredictable and irregular as possible.
Also, no players are allowed to consume caffeine for the duration of the game (which would last for weeks), unless they draw a Caffeine Card, which allows them one or more caffeinated beverage of a certain kind.
