Do you enjoy Sudoku puzzles? Are you fascinated by the Washington Metro? Now, you can do both at the same time with this hybrid game which uses Metro station facts and the classic Sudoku. Adam Bressler wrote the game, and Nick Keenan coded up this interactive version. Enjoy!

Instructions: The following questions (A-T) are answered with a single digit number (1 through 9). Solve the questions and insert the solution into the corresponding position in the Sudoku grid. Using those answers, solve the remainder of the Sudoku puzzle in accordance with the standard rules of Sudoku. Some of the numbers in the grid are already provided to you.

Tips: If you are uncertain about an answer, it is best to skip that question and return when you have narrowed down the possible solutions. Each question in this puzzle is related to the full names of Metro stations (including subtitles and other elements), as shown on the current Metrorail map as of January 9, 2018.
