1. In the Games at Twilight, the kids are playing two games. First in the afternoon they play hide and seek and when twilight came they were playing the funeral game. The main character Ravi wanted to win the game of hide and seek and he hid in a shed for a long time. He thought he won the game when dashed to the den only to find that the other kids have forgotten about him and have started playing the funeral game.
2. Twilight is a symbolic time of the day here. A potent symbol at that. Twilight symbolizes the transitional period, the end of the day and the beginning of the night. Twilight here relates to Ravi specifically. During twilight the day is ending as is Ravi's childhood as he learns that the world does not revolve around him.
