Brückenbauen

In this two-player game the task is to build a bridge from one end of the
playfield to the other before the other player does the same faster. The
playfield consists of 17×17 cells, already filled with blue and red cells. The
players have to click in the white (empty) cells and the color will change
accordingly to the color of the player and a small bridge is created. A player
can hinder his opponent by using the empty cell himself, creating different
routes.
