Tubedoku is a 3x3 grid that you have to fill with six different tube stations that satisfy the descriptions both the row and column. Similar to the New York Times' Wordle, a new puzzle is released every day. Unlike regular sudoko, there are normally multiple possible answers for each square. For example, a station that's on the Central line and has no repeating letters could be Bank or Fairlop, and a station ending in Green and in Zone 2 could be Bethnal Green, Parsons Green or Kensal Green.
