Big Bang is one of several games playable with the Katarenga board and pieces. This game is invented by the author of Katarenga. In this game the pawns move from the centre of the board to the edge squares. Each player tries to be the first to occupy all edge squares of one colour, each player chosing a different colour. Play ceases as soon as one player wins and the winner scores 1 point for each opposing pawn still wandering elsewhere in the universe.
