A puzzle-solving game where you have to hit the streets to play. “The Underground Mysteries” is a puzzle trail where you ride the trains around Tokyo using a 24-hour train ticket, solve puzzles at your own pace, and discover new places! Be part of the story and embark on a puzzle adventure that lets you see Tokyo and the metro train lines in a different light!
STEP 1) Go to a designated station to buy a game kit or purchase it online (pick-up necessary)
STEP 2) Follow the instructions on your game kit, solve the first puzzle, and head for that station
STEP 3) Pick up clues at the next station, solve the next puzzle, and go to the next location
STEP 4) Reach the final answer and submit it online on the official website to clear the game!
*Note: Although some puzzles may differ between the different language game kits, all locations visited are the same. Therefore, players holding a Japanese, English, and Chinese game kit can play together.
