I recently discovered Phil, an HTML5 crossword puzzle maker (here it is on GitHub). I’ve always wanted to make a crossword puzzle, but it seemed overwhelming. But with Phil, I found it fun and addicting!
So, here is my first creation. It has a mathematical theme. I’ve enjoyed solving crossword puzzles off and on over the years, but I would by no means call myself an aficionado. Thus, I tried my best to write typical crossword-like clues. If anyone would like to offer feedback, post it in the comments below or send me comments by email.
