Review by Dorothy Millard (PC Inform Version, part of Disk 1289)

At the start you read "Yet another darn treasure hunt game."
After a few moves you will meet Charlie who will readily give you
his Fifteen Puzzle as he is stuck in it anyway.  It is one of
those puzzles where you move a sliding piece in an attempt to get
all the pieces in the correct order.  Instructions on how to play
the Fifteen Puzzle can be obtained by typing INFO PUZZLE. If you
can't be bothered working out the puzzle typing PLAY CHEAT
completes it, but you miss out on one point and will only get 4/5
at the end.

Fifteen is a comparatively simple game with the most difficult
puzzle being how to have the remote working when you arrive at the
security boxes containing the diamond (green) and ruby (red).
This took me quite some time to work out.  Your movement turns the
light on and off so it was obvious that you must move around until
it is in the right state, but it isn't quite as easy as it first
appears.

There are only four treasures to collect so it isn't a long game.
Quite enjoyable but nothing special.
