How to play

Doku is a nine-cell grid, once a day. Each cell crosses two criteria: find an answer that satisfies both.

1. 1Pick your universeMetro stations, countries, capitals, champions, Pokémon: each universe has its daily grid, the same for everyone.
2. 2Fill 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.
3. 3Three livesA wrong answer costs a life. Out of lives, the game ends, but the cells you found still count.
4. 4Come 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 small bonus.
