How this daily challenge works

A hard puzzle with a fixed seed is generated every UTC day. All players compete for the fastest time.

  • Everyone gets the same UTC-day puzzle, so times are directly comparable.
  • Clear the board cleanly and submit your run to compete on the leaderboard.
  • Open today's board or revisit the last 14 challenge dates from the archive.
