I wrote a puzzle game for the Commodore 64 computer in BASIC V2. It is
a combination of a sliding-tile and "Lights Out" -type puzzles.
It can be played online at the link given below. The link is long
because the source code is contained in the link. To make the link
shorted, I had to remove the instructional part of the code. Here are
the instructions:
'Ducks in a Row'
This is a puzzle game. The objective
is to get all of the ducks facing the
same way. The player selects a duck
by entering its letter. The selected
duck and the neighboring ducks will
turn around and face the opposite
direction. If there is an empty space
nearby, the selected duck will move
into that space. The puzzle size can
be set from 2x2 (easy) up to 5x5 (hard).
