Ludus Chessunculus
Keys "s"=save "l"=load "b"=back once
John Cleaveland, 1974. Single-hoppers (bishops) move to the nearest like-colored hex. Double-jumpers move through one adjacent vacant like-colored hex to another adjacent to that hex. No pawn promotion.
These are simple illustrations rather than strong opponents.
