The daily puzzle

Find the capital city that ticks both criteria

Every cell crosses its row criterion with its column criterion: find an answer that matches both. The rarer your answer among players, the more points it scores.

London is in Europe and has more than 5 million people: it matches both criteria of its cell. A capital can only be used once.

How it works

  1. 1Fill the nine cellsTap a cell and search for your answer. It must match both its row and its column criteria, and each answer can only be used once.
  2. 2Three livesA wrong answer costs a life. Out of lives, the game ends, but the cells you found still count.
  3. 3Come back tomorrowOne game per universe per day. Playing every day grows your streak.
How points work

The rarer your answer among players, the more it scores. An answer nobody thinks of is worth far more than the obvious one. Mistakes cost a few points, and finishing fast earns a bonus.

By the city in its administrative sense, not the whole metropolitan area.
