In Subwaydle, players aim to guess the SUBWAYDLE within six tries by selecting a valid subway trip involving three trains with available transfers. Each guess must adhere to the rules of the New York City Subway system, including no backtracking and utilizing transfers only when lines diverge.
Green indicates a correct train in the correct spot, yellow signifies a correct train in the wrong spot, and grey denotes trains not part of the trip. Players navigate through the puzzle, aiming to find the precise routing that matches the day's challenge.
