Shops and houses board up their windows to prevent damage, and the game can go up alleyways, into yards and up streets.
Traditionally, the first ever game was played with an Englishman's head. The ribbons on it symbolise his hair.
There are two games, one for young men, which starts at 12pm, and the second is the adult game, starting at 2pm, which can last for several hours.
The game is always played on the Thursday after shrove Tuesday, or the week after, depending on when the first new moon falls after Candlemas.
