Granny’s forty-something year old grandson is living in her basement. He is a quiet man that goes to work and keeps to himself. Sometimes granny hears odd noises from the basement. He explains it is the furnace in the old house and insists that she does not check it out. Granny doesn’t suspect a thing, but she should. Her grandson has a secret. You are about to find out what that is when you find yourself locked up in the basement. You have one hour while he is out running errands for granny to escape before you become another secret lost in the basement......

    Must do!

    It was so much fun! I was a little nervous beforehand that I might not make it out on my first time. But we did and even set the new record for the zombie escape which was a bonus! So don't let that hold you back, it is fun regardless. We will definitely be back sometime to try the other rooms!

    Fun date night

    Myself, husband and some great friends went to 307 Mysteries as a date night and did the Alien Spaceship, we then booked for another night to do the Russian Spy and Mad Scientist rooms! We love it and have had a blast so far, can’t wait to see this business grow and continue to try/escape the rooms. We will be taking our kids to see if they can help us escape faster!

Why Us

The escape rooms at 307 Mysteries are designed and ran by me - Lezlie Kinsinger. I grew up in Gillette and returned after going to college. I wanted to create something fun and entertaining for adults, kids, families, and businesses that is affordable.

Escape rooms are a fun way to spend some time away from your cellphone and make you think outside the box. They promote team building and communication between individuals. If you need a special escape room for an event, I can create one for you.
