The daily puzzle

Find the London Underground station 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.

Bank is on the Central line and in Zone 1: it matches both criteria of its cell. A station 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.

Frequently asked questions

Do Overground stations count?

Answers are Underground stations. An interchange with the Overground or with a mainline terminus is used as a criterion.

Are station names in English?

Yes. Stations keep their English name in both languages, only the criteria are translated.

Is Metrodoku London free?

Yes. Today's grid and free play are free to play in the browser, no account required. The Doku app is also available on iPhone and Android, with the same grids and the same progress.
