 Tubes: The Game
   

         The&nb sp; object of Tubes is to keep the large beaker as free of
        atoms  as  is  possible.  This is accomplished by lining up 3 or
        more like coloured atoms in a row,  vertically, horizontally, or
        diagonally.  Use  the  test  tube you control to catch the atoms
        falling  from the dispenser tubes and place them into the beaker
        at  your  discretion.  The  game  is  over  when  you've dropped
        enough  atoms  to  exceed the drop limit,  or when you've filled
        up the beaker with atoms.
