DokuThe daily puzzle
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.
Metrodoku is a daily game that crosses the idea of sudoku with the metro map. The grid has nine cells. Every row and every column carries a criterion, and the cell where they meet wants a station that satisfies both. Northern line crossed with Zone 1: Angel works, Morden doesn't.
A new grid comes out every day, the same one for every player. You get three lives and a score that rewards rare answers: everyone answers King's Cross, answer something else. Free play generates as many grids as you like, from easy to expert, so you can practise without waiting for tomorrow.

No. Each station can only be placed once in the grid, even if it fits the criteria of several cells.
