FrameGuessr

A daily guessing game: each day there's one movie or TV show to identify, revealed through progressive hints, the still image first, then a tagline, then the year and genre, and you get three guesses.

Most of the interesting work is in the parts that keep it honest and resilient:

• Server-side answer checking. Guesses are validated on the server against the day's answer, so the correct title never sits in the browser waiting to be read out of the page source.
• Resilient data fetching. Calls to the external movie database sit behind a two-tier cache with retries and backoff, so an upstream rate limit doesn't take down the day's puzzle.
• Timezone-safe daily reset. The puzzle is keyed by date string and rolled over client-side, which avoids the server and the browser disagreeing about what day it is.
• No lost progress. Play logged out and your history lives in local storage; sign in later and it merges into your account instead of being thrown away.
