A friend of mine just showed me Puzzle Pirates today. It’s a persistent online game where thousands of players converge to duke it out in various puzzle games. It’s totally free to play, too! Here’s a snippet from their “About” page.

Battle scallywags, find sunken treasure and get yer sea legs aboard a stalwart pirate ship… all from your web browser! Before you install Puzzle Pirates, take a Pirate Adventure and lead yer mates on bold pirate quests! Master the art of swordplay and sea-dog brawling on the high seas, explore uncharted islands and claim yer pirate booty! Yer adventure awaits!

If you’re looking for a way to kill some time and you’re a fan of puzzle games, then check out the website. It looks like it might be fun.
