I had a great time at De Code. I went with 5 friends, and each of us had never tried a room escape before. We did the Child's Play room as the other rooms were booked and Ancient Mystery was unavailable.
Since it was our first time we had a little bit of trouble getting started but eventually started to figure things out. One of the clues was missing in the room so one of the staff members had to go and grab a replacement for us, but other than that it was set up really nicely and was lots of fun.
Everyone was really nice and they offer for you to stay after your 45 minutes is up to play board games, have photos taken and grab something to eat. A great experience all around and I will be back to try out the other rooms!
