Subwaydle

Subwaydle swaps Wordle's letters for subway lines. The day's puzzle names two stations, such as Mt Eden Av to 20 Av, and says how many transfers to use. Your guess is a sequence of three trains that really can make that trip with transfers between them, and there is one routing that matches the puzzle of the day, which may or may not be the fastest.

After each guess the tiles are coloured. Green means that train is in the right spot of the trip; a train shown in blue means another train sharing the same routing belongs in that spot; yellow means the train is part of the trip but in the wrong spot; grey means it is not used at all. You have six tries. Once you solve it, a map traces the day's journey line by line and names the station where each train is boarded.

The rules follow the real system closely: routings are based on the midday schedule, weekend puzzles use regular weekend routings, transfers are only allowed where lines split, no station can be passed through twice, and the Staten Island Railway and the ferry link at South Ferry count. Several stations share a name, which adds to the challenge.

Subwaydle was made by Sunny Ng, and its source code is public on GitHub. The subway route symbols are used with the MTA's permission. Puzzles are numbered from 29 January 2022, and the result you share says whether it was a weekday or a Weekend Edition. The previous day's answer and stats are posted on the game's social account. It suits New Yorkers, transit fans and anyone who knows the A from the C.
