T-game

T-game can be played on a rectangular grid of any size. Even the small 6x6 grid used in these rule illustrations leads to interesting play. Each player in turn draws a horizontal or vertical line that connects two previously drawn parallel lines. The new line must be drawn along the board's grid lines and must be perpendicular to both of the lines it connects. At the start of the game, the board edges are considered to be previously drawn lines. A player may not draw a line that crosses a previously drawn line, nor may a line connect with the end of a previously drawn line. In other words, lines may only come together at T intersections; there may never be a four-way crossing. The winner is the last player able to move.
