recommends I had a little trouble with the download, but we got it after a little effort. We had six kids on New Year's Eve ages 4 to 14 and it went pretty well. My husband made a "time machine" out of some lights, buttons, knobs, an old broken clock, and an old Halloween fog machine. We enjoyed making s'mores to celebrate the Inca's discovery of chocolate-making and drank "potion" made of water and flavor drops. The Escape Room took about 1-1/4 hours for those kids. I may have hidden some of the clues a little too well. In retrospect, all six kids said they would do it again sometime. It was the hit of our NYE party.
