DailyMetro is a free daily game about the metro, subway, tram and tube networks people ride every day. It is made by one person, Eliott Gandiolle, an independent developer based in Paris. There is no company behind it, no investors and no editorial team: when this page says “we”, it means one developer and a build script.
Every day at local midnight, each city gets one new puzzle, the same one for every player in that city, so results are actually comparable. 11 cities are playable today and 11 more are built and scheduled, together covering 2,091 guessable stations on 110 lines, with the interface in 8 languages.
There are three modes. Classic gives you clue columns after every guess: which lines serve the answer, the compass direction and distance to it, its ridership tier, the first and last letters of its name, its fare zone or district, the year it opened and where its name comes from. Map asks you to place the station on the network plan and scores how close the pin lands. Photo, available in 11 of the live cities, shows a photograph of a street entrance with the name blurred out.
No account, no sign-up, no download, no guess limit. It runs in any browser and installs as a progressive web app. Your progress is kept in your own browser and never sent to a server.
Eliott Gandiolle, an independent developer in Paris, France. I build a small family of free daily games in my own time. I write the code, assemble the datasets, draw the maps and write the articles in the blog. The formal publisher details, as French law requires them, are on the legal notice.
I am not a transit authority, a cartographer or a statistician, and this site is not an official source for anything. It is a game built carefully on other people's published open data, which is why the sourcing below matters more than my opinion does.
Station names, coordinates, opening years and line memberships are queried from Wikidata, which publishes its data under CC0. Ridership figures are read from the published tables that the operators and Wikipedia maintain for each network, and the year and the source travel with the number.
City outlines, administrative districts and neighbourhood boundaries come from OpenStreetMap, © OpenStreetMap contributors, used under the Open Database Licence (ODbL). The street basemaps drawn behind the network maps are CARTO tiles rendered from the same OpenStreetMap data, credited on every map that uses them.
The entrance photographs in Photo mode come from Wikimedia Commons, and only files under a Creative Commons or public-domain licence are used; the author, the licence and the source file are recorded for each one. Nothing on this site is scraped from an operator's own app or website.
Datasets are rebuilt by script, never edited by hand, so a page cannot quote a station the game no longer plays. Data can still be wrong or out of date: if you find an error, the fastest way to get it fixed is to tell me.
The puzzle is derived from the calendar date alone, in the city's own timezone, with no clock and no randomness at play time. The date is hashed and the hash seeds a permutation of that city's playable stations, so every player in a city gets the same station on the same day, and any past day can be replayed exactly as it was.
Since July 2026 the pick walks a no-repeat cycle rather than drawing freely, so a station cannot come back until the city's whole pool has been used. Days played before that changeover still resolve to the station they were played with: an already-played day is never rewritten.
DailyMetro is not affiliated with, endorsed by, sponsored by or connected to RATP, Île-de-France Mobilités, Transport for London, the MTA, BVG, Metro de Madrid, or any other transit operator or authority. Network names, line names and numbers, station names and their liveries belong to their respective operators and are used here only to describe the real networks the game is about.
The maps in the game are schematic drawings made for gameplay from open data. They are not official network maps, they are not navigation aids, and they should not be used to plan a journey.
Ridership tiers, opening years and district labels are the best figures the open sources publish, not the operators' own current numbers. Where a network has changed recently, the game will lag it.
DailyMetro is free and always has been. Running costs are covered by third-party advertising, served by Google through AdSense, and by entirely voluntary Ko-fi donations. Nothing is sold to players, there is no paid tier, and no feature is withheld from anyone. What is and is not collected, and what the advertising does with cookies, is set out in full on the privacy page.
Corrections, questions, press, or a note about a station that is plainly wrong: write to dailymetrolive@gmail.com and it reaches me directly. There is no support team and no ticket system, so replies are personal and occasionally slow.
