I just submitted an entry - 8puzzle. Just to clarify, I used ? for print and removed all spaces to squeeze things into the line length limit (I hope - *grin*). If you load the program and list it, it will obviously show longer lines due to the "de-tokenization". I assumed from the description that this was consistent with the rules. Let me know if otherwise. The puzzle isn't the most exciting, eye catching thing so far. But it was a bit of a computational challenge to put together so compactly, and the game play is actually pretty fun and not too time consuming or confusing. Looking forward to what folks think.
It's the first time I've done this, so I'm not quite sure what to expect *grin*.
PS I included a bit about the original game for folks that may not have encounter where this comes from.
