Yeah, you're right. I guess I missed that. It's nice to see a puzzle where we can understand the rules, though.
I like making puzzles where part of the puzzle is figuring out the rules. I consider them 'thinking outside the box' puzzles or creative-thinking puzzles. It's my style, if it's not your cup of tea, feel free to look elsewhere *shrugs*.
Bah, should be asleep...instead of volunteering to pick ppl up at the airport at ridiculous hours .
