Droidle is a five-letter word puzzle with an Android twist: the hidden answer is always a tech or device term like ROBOT, PIXEL or CACHE. Unlike a once-a-day puzzle, it deals a fresh word every round, so you can chase an endless win streak without waiting for tomorrow. Most rounds take a minute or two, a quick brain teaser for a coffee break on phone or desktop. Droidle is completely free, needs no app or sign-up, and works offline, with your streak and win rate stored privately on your own device.
Every guess is a small deduction puzzle: read the green, yellow and grey clues to narrow the field down to one answer. It stretches your vocabulary while training pattern recognition and the working memory you need to track which letters are already ruled in or out.

Built as a single HTML file, with no frameworks, no network calls, no tracking. Pure DOM + CSS, vanilla JavaScript, Web Audio for sound, and your streak and win rate saved in localStorage. Fully offline; drops into any page via <iframe>.
