'Tis the season to be jolly and test your wits for a good puzzle

Two of my favorite things (Christmas and puzzles) combined together in one game! The game involves discovering riddles underneath the busy city, and did I mention the game is on Christmas? Yes, I did. I love Christmas! The game may have a bit of a challenge, so it's handy to play some ads to get a hint. Just don't overdo it or you'll miss the fun of it.
