I've become a big fan of word games over the past few           ║▐
║     years. First starting with mini crosswords, then upgrading      ║▐
║     to full-sized crosswords, eventually I discovered NYT           ║▐
║     Spelling Bee, and most recently joining in on Wordle craze.     ║▐
║     Word games consume large portions of my downtime as I find      ║▐
║     that as relaxing and I do mentally challenging.                 ║▐
║                                                                     ║▐
║     Earlier in the year, I was out for a run, and I had an idea     ║▐
║     for a word game. The concept was a play would start with a      ║▐
║     short-ish word and the challenge would be making a series       ║▐
║     of single-letter changes to modify that word to eventually      ║▐
║     match a completely new word, all while ensuring each            ║▐
║     single-letter change resulted in a dictionary-verified          ║▐
║     word.                                                           ║▐
║                                                                     ║▐
║     Over the next few days and runs (I do a lot of my best          ║▐
║     thinking while running), I was able to refine the interface     ║▐
║     and mechanics. The starting and ending word would be given      ║▐
║     up front, the list of word modifications would be shown and     ║▐
║     change count would be tracked, and there needed to be a         ║▐
║     defined number of steps to get from starting word to ending     ║▐
║     word. I still needed a theme, and again during a run, I had     ║▐
║     my eureka moment, giving the game a golf theme!                 ║▐
║                                                                     ║▐
║     I'm not a golfer, so I had to do a little research, but I       ║▐
║     was immediately struck by the idea that the recommended         ║▐
║     number of modifications to the starting word could be par.      ║▐
║     That would set up an opportunity for players seeking a          ║▐
║     challenge to try and find ways to get to the ending word in     ║▐
║     less than par, an important part of golf. As I continued        ║▐
║     down this theme, everything seemed to easily fall in place      ║▐
║     each modification could be called a stroke, if the player       ║▐
║     needed to backtrack it could be called a mulligan, the          ║▐
║     player's rank would be a matter of strokes relative to par.     ║▐
║                                                                     ║▐

║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ I created a few proof-of-concept games and had my friends ║▐ ║ and family play for feedback. Eventually, I landed on five ║▐ ║ strokes/modifications feeling like the right amount. It ║▐ ║ also helped to limit word size words with less than four ║▐ ║ characters made games too easy, and words with more than ║▐ ║ seven became too restricting. ║▐ ║ ║▐ ║ Finally, I had a game concept and name (I liked ParFive ║▐ ║ since it alluded to the game's most consistent feature), ║▐ ║ but I needed an algorithm for generating the puzzles. The ║▐ ║ hardest part of this entire process was refining a ║▐ ║ dictionary file to choose words from. I ended up basing my ║▐ ║ dictionary word list on SCOWL's word lists, while filtering ║▐ ║ the list through Luis von Ahn's offensive/profane word list. ║▐ ║ In the end, I had two different dictionaries, a list of ║▐ ║ more common words I could generate puzzles from, and a more ║▐ ║ expansive list that users could verify words against, ║▐ ║ giving more opportunity to complete puzzles under par. ║▐ ║ ║▐ ║
║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ ║▐ ║ The puzzle generation algorithm is still a work in ║▐ ║ progress, but in its simplest form, it begins by picking a ║▐ ║ starting word from my common words list at random. Then, it ║▐ ║ creates a list of words it can branch to next my making a ║▐ ║ single-character modification. A word is chosen from that ║▐ ║ list and random, and the process repeats four more times to ║▐ ║ get the ending word. The algorithm works similarly to a ║▐ ║ one-way function, as it's easy to generate the puzzles, but ║▐ ║ harder to retrace the path once given the output. ║▐ ║ ║▐ ║ ParFive is live, and it is updated daily. Putt your word ║▐ ║ skills to the test and give it a try! ║▐ ║ ║▐ ║ Play ParFive! ║▐
