He can call his own puzzles marzipan kangaroos if he wants and I won't complain. However, he publicly calls other pubication's puzzles INVALID. He uses language like
"sudoku-lookalikes" implying they are not actually Sudokus. This is all about marketing. This has caused great confusion. There are many threads in this (and other) forum in which one person had trouble with a puzzle from another source, posted it here for help, and was told that the puzzle was INVALID by someone who had tried to dub it into Pappocom's software. Though he explains what he means by INVALID and ARGUABLY UNFAIR, most people don't see those explanations and/or don't understand what he means. The user must make a big effort to find these definitions. I didn't see them myself when I first got the software -- I assumed it was a glitch.
If you were to download a chess program that explained that castling was an invalid move, could you defend this? If the program wouldn't allow you to examine games from that included castling or allow you to make that move in the game -- well, they can do what they want with their own software, right? If this seems far fetched ...
Currently, the most popular board game in Japan is Go, followed by Shogi. Shogi is a chess-type game that is far superior to chess but still relatively unknown outside of Japan and the abstract strategy game playing world. A big difference between the FIDE chess you are familiar with and Shogi is that a captured piece is not eliminated, but instead, becomes part of the capturer's army, who can later "drop" a piece back onto the board instead of making a move. Because of this, draws are very rare, less than 1% of championship level games. If Wayne travels back to Japan, "discovers" Shogi, successfully popularizes it in the UK and elsewhere with his software called "Shogi" -- software that calls "drops" INVALID and does not allow them, what are we to do? The word "Shogi" is in the public domain, just as "Chess" is. He can do what he wants with his own software. If he doesn't like drops, why should he have to put up with them?
Because he should. And if he wanted to change the rules to Sudoku, he should have changed the name and made it very clear which of his specifications are NOT part of the traditional puzzle. I don't get it -- virtually all other Sudoku software will allow the user to import or dub in puzzles that are more difficult than the software will generate and/or solve without needing to explain this. (Simple Sudoku, SadMan, etc.)
(And yes, at least one person made a "Shogi" program some time ago that didn't include or even mention the possiblities of "drops". I don't know if he didn't understand the game or just didn't like the drop rule. Fortunately, his software was not wildly successful and had little impact.)
