The Dark Game was played at Marcus' House at night-time. The object of the game was for the seeker to find the two hiders in Marcus' pitch black basement. The seeker waited upstairs in the light for the two hiders to find their hiding places and shut the light off. Then they could venture downstairs. A good strategy was to say funny things to make the hiders laugh, so you could find their places. Once both hiders were found, one of them became the seeker.
The game was played best when the hit movie "War Games" was playing in the room where the seeker is waiting.
