This game was written in Borland Delphi 3. It was the only game I wrote with it.
There's not much else that can be said about it apart from a rare bug that may not clear all the expected tiles.
The bug is not so bad as to ruin the game as any player can work out the next free space that should have been cleared.
I no longer have Delphi so I cannot fix it.
