The game is played on a board like the diagram shown above. The players alternately connect two orthogonally adjacent dots of their own color with a bridge -- either a length of plastic or (if playing on paper) simply a line of their color. A line may not cross another line already played. The object is to connect the opposite edges of the board that are your color.Bridg-It thus bears a superficial resemblance to TwixT. (Does anyone know whether one game inspired the other? They seem to have originated about the same time.) But Bridg-It is not nearly so deep a game: it was solved completely by Oliver Gross in the 1960s. His solution appears at the bottom of the page.Although Bridg-It in the original form is solved, it might be salvaged by making some variations on the rules. One possibility is Double-Move Bridg-It, in which the first player plays one bridge on his first move, and all later moves consist of playing two bridges. Since the board is then filling up twice as fast, I would propose playing Double-Move Bridg-It on a larger board, say 7x8 for each color as shown below.
