Game for two teems YELLOW and RED As in ordinary blockbuster, the teams have to cross the field The teams in turn chose tiles by number, in any order they want. But eventually the tiles should join at the sides. By clicking on the number of the tile the teams have to answer the question. Each good answer allows that team to colour the tile to their colour.
