About Métrodoku

Métrodoku moves the grid format of Immaculate Grid and GeoGrid underground, to the 321 stations of the Paris metro. Each day's board has three clues across the top and three down the side, and every cell needs a station that answers both: on line 14, in an even-numbered arrondissement, named after a historical figure, with an RER connection, within 3 km of the Eiffel Tower and so on. The whole game is in French. Its maker, who builds it alone, wrote in May 2026 that it had passed a month online and was drawing 40,000 to 50,000 players a day.

You type a station name and pick it from the suggestions. A station placed in the grid stays there and cannot be used twice, and three wrong answers end the game. Each correct answer is scored by how few other players chose it for that cell, so a well-known hub earns little and an obscure stop on the edge of the network earns more. The FAQ explains that the rarity figures are tied to a fixed reference published with the grid, so early players are not at an advantage. After the game you can click any cell to see every accepted answer.

The archive lets you replay earlier grids as bonus puzzles that do not count towards your statistics. Métrodoku suits Parisians, regular metro riders and transport fans; a casual visitor will find the clues about lines and transfers hard without a map open. Players of the country grids and sports grids will know the rules at once.

How to play Métrodoku

1. Open metrodoku.fr and read the three clues above the grid and the three down its side.
2. Click a cell and type a Paris metro station that fits both its row and its column clue, then choose it from the list.
3. Click a clue you do not understand to see its explanation.
4. Fill all nine cells before you make three mistakes; a placed station cannot be moved or used again.
5. At the end, check your rarity score out of 900 and click the cells to see the other answers, then share your result.

Tips

• Go for less used stations when you are sure of them: the rarer the answer for that cell, the more it scores.
• Watch transfers: the game only counts lines that actually stop at the station itself, not ones reached through a corridor to a neighbouring station.
• Keep a metro map open the first few times, especially for clues about arrondissements and line ends.
• Fill the cell with the fewest possible answers first, so you do not spend a station it needed elsewhere.
