Eight Links -Commodore 64-

 A C64 variant of 8 Links by KWAYNE

Eight Links is a Commodore 64 variant of 8 Links by Anton,
a seemingly simple puzzle game where you have to put down tiles with
links to their neighbors and create the longest possible chain of
connected tiles for a greater score. In this game, however, the object
is somewhat simpler: just find as many connections as possible for each
tile on the same 4×4 grid.
