Daily challenge

Goal

One puzzle per calendar day, same for everyone. Finish it to see your place on the leaderboard.

Shared daily run

New puzzle at 00:00 UTC · Streaks follow your profile

Everyone gets the same flag and rules for that UTC day — scores compare on one shared run.

Streaks

Missing a day may reset a streak, depending on how the daily screen measures your run — the post-game summary is the source of truth.

How to play

Start from the home page, or use the direct link below.

The screen always shows that day’s rules and scoring for the run you’re on.

Tips

  • Midnight UTC: A new puzzle starts each day; your streak still lives on your profile.
  • Accuracy over speed when wrong answers are expensive — the scoring screen is the final word.
