Every word you guess goes into your collection (the daily challenge and custom words don't count). The game picks words you haven't collected yet first, so every win brings you closer to completing a category. Words guessed with a ๐ก hint are marked - guess them again without one to clear the mark. Your collection is saved on this device only: clearing your browser's data for this site resets it, and some browsers (Safari on iPhone, for one) clear it after a while without a visit.
