This was my first escape room experience. I went with some coworkers during a conference and we did the Heist and FBI rooms.
We had a great experience, my coworkers who had completed 6-8 rooms said that the rooms we did were some of the best rooms they had done. As a first timer I don't have quite as much to compare to but I really enjoyed it. I thought that both rooms were challenging but fair, and no gimmicks or puzzles were reused between the rooms. We managed to succeed in both rooms but we were firing on all cylinders the entire time and I could see how some groups could get stuck or could take a lot longer than we did on certain puzzles.
The guys who work there (Tolga and Cory) are super nice and are really into the escape room world. If you are a veteran, they are super knowledgeable and love to talk about the intricacies and design philosophy.
All in all I had a great experience with Riddle escape room. I'm definitely hooked now and will be trying some in my hometown!
