       Five or More is the GNOME port of a once-popular computer game. Align five or
       more objects of the same color into a line to cause them to disappear and
       score points. Earn many more points by lining up as many objects as possible
       before clearing them.

       More objects appear after every turn. Play for as long as possible, until the
       board is completely full!
