This is a great game if you like puzzles, codes etc. What I like the most is that hints are included and the time is specified on each hint when to use it. So the game progressed nicely as we never got too frustrated if we couldn't get it. We did use a few but not all hints. Without the hints the game would be very frustrated and sometimes even impossible if you are on the wrong track. Another nice feature is that it comes with four rooms (i.e. Four scenerios) each one is supposed to be one hour. We only played the first one, the prison break. The game was played with two adults and three kids ages 13, 15 and 10. The ten year old got bored quickly, but the rest of us enjoyed it.
