When we went our group was from 8 to 77 years old. You can just imagine the fun we had trying to combine our solving skills!!
There are rooms suited for 12 yr olds. Call and ask the reps
I took my son for his 13th B-day with his friends and they had a blast. 12 years old is a good age to take him there.
I'm not certain on the minimum age, but there is nothing present that would be considered violent or inappropriate for a young child.
