Yohoho.io

Yohoho.io may be a great pirates IO game to enjoy online and for free of charge, of course. Control your crazy little pirate on an island filled with enemies willing to be the last man standing, and collect as many coins as you'll to extend your size and, most vital, your weapon's size. Beat, stab or swing the crap out of your opponents and earn coins to unlock new, stronger characters. Once during a while, a deadly gas will start moving closer to the middle of the sector, leaving you no option but to confront your enemies, so hiding and running won't do match. Kill all of them and luxuriate on this game.
