Only one word

Receive a Wikipedia article and find a word that occurs only one time in the entire text.

Are you fast? Can you find a word with 4 or less characters? How many attempts do you need? Post your results in the comments below!

Plays best in Firefox (because the timer doesn't have decimals). There are 15 different articles of which you will be assigned one at random.

Note: The game does not take into account text in info boxes.

Known bugs

After managing to set up the Wikipedia connection, things went... a little quick...

• User input not escaped before becoming regex :)
• Non-Firefox browsers show the time in unreadable format (like 0-10 decimals , changing each frame. Firefox which I used just shows whole numbers.)
• (Not sure if I can trust the javascript regex for word boundaries)
• The part with "This article is about..." pretty much always includes something unrelated to the article and should be ignored.

Other thoughts and personal

With more time, I would have made the game flow better. Simple online high scores for different categories: shortest word, fastest time, fewest attempts needed. More carefully chosen articles as well perhaps (the current ones have roughly 15% words that only occur once), and maybe you would have to do 5 articles in a row so you get into the flow. Perhaps a scoring system that takes into account all the details that I think of as categories.

For personal reasons, I could only work on this game for 10 hours on the Sunday, most of which went to figuring out how to get the data from Wikipedia without getting stuck in cross-domain security stuff.
