How the daily challenge works
A new challenge is selected every day at 00:00 UTC. The page reads a server-side schedule generated from the verified challenge library, so refreshing the page or clearing localStorage does not change today's puzzle. localStorage is used only for progress, completion, time, best move count, and unfinished state on this device.
