Board and video games from films can sometimes be overcomplicated to play as they are rushed to the shelves. The Da Vinci code game has its fair share of rules that need to be read about 20 times in the booklet before playing. However, the inclusion of a practice mystery where the clues are easier helps to overcome this. Once you do learn, you get quite an enjoyable game where the focus isn't just on finding out the overall mystery phrase, but on what you have learned from the clues e.g. what did x picture show etc. Da Vinci code will appeal to people who like puzzle-solving and have an interest in history. If you have already read the book, it won't give you an unfair advantage as most of the mysteries do not directly relate to the plot.
However, this game has a limited life span as there are only 15 mysteries to solve - probably so an expansion pack can be brought out later. Although with 4 players, it takes about an hour to do each one. It's a board game that's more suited to playing with the same group of people over and over rather than trying to teach new sets of people each time you play. A big problem is that we had to alter some of the minor rules to make the game more playable. For example, to successfully use the cryptex tool, you needed more than the allotted 30 seconds. Another issue, is the questions at the end can sometimes be answered based on common general knowledge rather than paying attention to the game.
Overall, me and my uni friends have had a lot of fun with this game and would especially recommend it to people who enjoy puzzles.
