I am an Escape Room buff. I love Escape Rooms and I love trying to solve puzzles (though admittedly, I am not that good at it). When I saw the advertisements for this particular challenge on the walls of the Metro when I went to Japan with my friends, I knew that I had to give it a shot. On my second to my last day in Japan on October 16, 2019, I made the decision to give this particular challenge a try. Unfortunately though, I was going to have to play this game solo. I went by myself to the Shinjuku station on the Maranouchi line, and bought a game kit for 2,400 yen (~$24 in U.S.). There's game kits for both Japanese and English Speakers. I got the one for the English Speakers. Once you get the game kit, you can go ahead and get started. Each individual person does not need to get a Game Kit. As long as one person in your team has it, you are fine. As an additional note: If you buy at least 2 game kits, you have the chance to get a limited edition Tokyo Metro The Underground Mysteries hand towel. After I finished my challenge, I ended up buying another game kit, just because I wanted the hand towel. Without giving too much away, the premise of this activity is simple. You're given a Game Kit. The Game Kit includes a 24 hour metro ticket, varying series of items (such as envelopes, pamphlets, and brochures, etc.) that you can only open at certain times, a pen, a puzzle book, and a folder case that holds everything. To begin your adventure, you need to take a look at the puzzle book. In the puzzle book are a series of puzzles that you need to solve in order to figure out where you need to go next. Once you figure out where you need to go, use your metro ticket to get there, and once you arrive at your destination, you are able to see if you're correct by using the next pages in your book and solving the puzzle or puzzles at your destination. Rinse and repeat, until you're able to complete the entire book. If you ever need help during the course of your challenge with any of the puzzles, you can use the Tokyo Metro The Underground Mysteries website to help you. (As a solo player, I can't tell you how valuable this website was for me. It helped me get the puzzles done in a timely manner, so that I was able to finish my adventure before I left the next day.) Though I wasn't able to thoroughly explore the places I ended up going to due to the limited time frame I had, the puzzle book itself has a lot of really good tourist information that detail good places to eat, landmarks to check out, and places to go. As someone that doesn't know any Japanese, this book was invaluable. I thought some of these areas were really cool, and they're definitely places I want to visit when I come back to Japan. Lastly, when it comes to my review of playing through this adventure, I honestly loved it. I thought the puzzles were very smart and thought-provoking. I had plenty of A-HA! moments, and I thought it was so cool that this adventure forced me to explore places of Tokyo that I would've never otherwise thought. Furthermore, playing this game also made me more comfortable with riding the metro. Once I finished this game, I was able to recant to my other friends, in detail exactly how I got to certain places. I felt super comfortable riding the metro and figuring out alternate ways to get to where I needed to go. But I think the best part of my experience was getting to interact with other players. As I said, I played this entire game by myself, so there were times when I would get stumped, even with the hints. There was this super sweet couple I played with, Alwyn, Justine, and their child, Oscar. They told me they love this game. Since we were all playing the same game, there were times that we would end up seeing each other at the same places and it was nice to catch up with them. In addition, because Alwyn and Justine were seasoned veterans of Tokyo Metro Underground Mysteries, when I got stuck, they gave me help with the puzzles, especially when I was unable to see the connection. As a solo player, I really appreciated the helpfulness and friendliness of my fellow players. The final part of the game to me, when I was able to meet up with Alwyn, Justine, and Oscar, as I solved the final puzzle is a scene that I will always remember. I know that I wouldn't have been able to thoroughly enjoy the game without their help and their hints. I definitely want to go back and play again sometime. TL; DR: If you want to explore different places in Tokyo, like escape rooms, and don't mind putting in the work to solve puzzles on your journey, I highly recommend this game.

I joined this event. It was very interesting because, through the problem-solving game, we can do sightseeing in Tokyo. I could find new wonderful places. Also, in the book of the event, there are some historical information and some explanation about the building and places. So, we can get some bits of knowledge by this event. I recommend this event because it is fun for us.

This is a very interesting game! We can go to different places with solving the puzzles, and like a small tourist. The puzzle is also very interesting, and the final answer will surprise you.
