The success of a puzzle game relies on having a good understanding of the average puzzle solving skill level of your user base and tailoring the puzzles to be doable in that context. I have played all games in "The Room" series and have found them all the be quite enjoyable. The logic puzzles are complicated but not drudgery. House of DaVinci is similar in many ways but the differences are numerous and mostly unwelcome. As mentioned by other reviewers, the game often requires you to click on literally every crack and crevice you see on the screen to find the "one way forward." And then when that fails you have to try to DRAG every crack and crevice every which way... This is not how I enjoy spending my "gaming time". Some of the puzzles in the game are most enjoyable and the art is superb. It feels like a focus group was really needed here to keep the puzzle design on a fair and reasonable footing. Also the puzzles are not just logic. Some rely on knowing details and history of Mathematics or rather obscure constructs (like the "Fibonacci Sequence") in order to proceed. If you're comfortable with all of the above requirements then you may find this game to be a satisfying way to pass the time.
