Published in the book BBC Micro Programs In BASIC from Newnes Technical Books. The book contains the following description:

This program is a computer implementation of those little plastic puzzles that you can buy, in which the user slides the pieces one at a time into the only available space. The object of the exercise is to arrange them in their natural order:

 A   B   C   D 
 E   F   G   H 
 I   J   K   L 
 M   N   O   

The advantage of this implementation over the plastic type is that every start condition is totally random and it is amazingly fast. Also, as a special dispensation, but only once per game, the user may swap any two letters, which is useful of course if you get into a situation you cannot see your way out of. Finally, the computer counts your moves and gives you a grading when — or if — you complete the puzzle.
