BreakLock

A hybrid of the game Mastermind and the Android pattern lock, BreakLock is a PWA puzzle game in which you are supposed to figure out the secret pattern lock combination. After each attempted combination, the game will tell you how many dots in your pattern were correct, and you should use that information to try to crack the lock in as few attempts as possible. With its full-screen display and smooth animations, it is hard to tell BreakLock apart from a native application. It also uses service workers to provide offline availability.
