It is common to draw the short lines as vertically connected to each other, so that the board appears to consist of just one row of very long lines, but the game is still played as if these were three separate rows of short lines. Such boards often also have three horizontal lines intersecting the vertical lines in order to illustrate that the lines are still in practice divided into three parallel rows. Some boards feature only a central horizontal line crossing the connected vertical lines, but the game is still played as if there were three rows of short lines.
