Play MétrodokuA fresh puzzle is waiting for you.
Métrodoku presents a compact daily challenge built around Paris metro geography and deduction. Each day a new 3x3 grid must be completed by placing distinct metro stations so every row matches a specified line and every column matches a specified arrondissement. Once placed, a station cannot be changed or reused elsewhere in the grid.
The site tracks progress with counters such as Score and Stations found and enforces a strict error limit of three per game. Categories and clues can be clicked for explanations, and at the end of a round you may click cells to view possible answers. The project is developed solo and accepts optional support via Ko-fi; contact is provided on the site.
How to play Métrodoku
- Open the daily Métrodoku 3x3 grid and read the label for each row and column to see the required metro line and arrondissement.
- Click an empty cell to choose a station that serves the indicated line and lies in the indicated arrondissement.
- Place stations one at a time; once placed a station is locked and cannot be moved or reused elsewhere on the grid.
- You are allowed up to three errors in a single game; exceeding that ends the round and reveals the solutions if you choose to abandon.
- Use the category labels to view explanations when unclear, and after the round click cells to inspect the possible answers for each slot.
Tips for Métrodoku
- Start with cells that combine rare lines or arrondissements; eliminating common stations narrows options for remaining cells.
- Keep track mentally or on paper of stations you have already used because no station can be placed more than once in a grid.
- Use the category click-to-explain feature when a label is ambiguous before committing to a station to avoid consuming your three-error allowance.
- If you are unsure about a placement, prefer leaving the cell empty rather than risking one of the three mistakes available.
