I didn't contribute much to the solving of the puzzle but I did find the gun (a toy)! Mostly, I enjoyed just watching our kids interact with each other. There was Son #1 who was fiddling with the physical props in the room, Son #2 who went to work cracking codes with letters and numbers, and my daughter who was trying different combinations on a locked box. Along with their spouses, it was fun watching them work.
Doing something different was kinda fun! Good to get out of the norm every once in a while. But that room definitely would've been a challenge for me on my own. Grab some friends and try it!
