“The Nancy Drew series has matured with each new release and we can see why it has come so far. In the 27th outing, you get to play the role of the famous female sleuth Nancy Drew once again, meet and interview colorful characters, switch between night and day in an innovative way, explore a cool looking high tech laboratory, read up on Tesla and electronics, play with interesting equipment, try out new mini-games in your cell phone, call the Hardy Boys and Deirdre for advice, recover yourself with Second Chances, and solve challenging puzzles.” -- GamesWarp

“Nancy Drew: The Deadly Device is the 27th game in the venerable Nancy Drew series from Her Interactive, and it is the best game in the series yet. With a great story, inspired puzzles, and equally good artwork and sound, it is difficult to find fault with this gem. While some critics unfamiliar with the series may regard the Nancy Drew games as mostly "games for girls", the developer's claim that they are for "mystery fans 10 to adult" is more accurate. I have not played an adventure game that has engrossed me this much for quite some time.” -- Adventure Classic Gaming

“Nancy Drew: The Deadly Device sees players investigating every nook and cranny of a high-tech research facility, with a small cast of interesting characters to play off of throughout... Immediately, you'll notice that the game's many conversations allow the story to progress evenly and organically. Meanwhile, with so many theories as to "whodunit," Nancy's collapsible task list will help you keep things straight. This task list is once again a great inclusion here, as it offers the ability to ask for hints on particular tasks. At the same time, these hints won't blatantly spoil the whole experience... The storyline is easily the best thing Nancy Drew: Deadly Device has going for it. With so many instalments under its proverbial belt, Her Interactive clearly knows how to develop an intriguing tale, and that's no exception here.” -- Gamezebo

“Nancy Drew The Deadly Device is the 27th edition of the Nancy Drew series on the PC/MAC from Her Interactive. They continue to churn out quality puzzle games that revolve around a mystery... I have said it before and I will say it again. I am very pleased Her Interactive continues to publish Nancy Drew games. They improve some aspect of the franchise in each and every game. The mysteries can keep family members engaged for weeks at a time.” -- Family Friendly Gaming

“Given that this is the 27th title in the Nancy Drew video game franchise, it was easy to see why these games keep getting made. While I believe that the next incarnations should take some hints from some of the new school, the old school feel of The Deadly Device was refreshing.” -- Dark Station

“I have had the chance to try quite a view of the most recent Nancy Drew games by Her Interactive, and to me it seems that each is getting better and better than the past versions that have been released. This game was no exception! The story was strong, the animation top-notch, and the overall gameplay was superb... This is the type of game that I like my daughter to play because it is not simply one where you sit and brainlessly play, but instead, you truly have to think to be able to move further in the game itself. All in all this is a great game that I would highly recommend to all, not just Nancy Drew fans, but all gamers young and old alike.” -- Dad of Divas

“And what an adventure it is. One that is both engaging and educational. Those who take the time to delve into the various books scattered around will learn a lot about Nikola Tesla, his inventions, and maybe a bit about patent injustice as well. The writing and production values are all top-notch, as you would expect from an experienced developer like Her Interactive.” -- True PC Gaming

“Nancy Drew: The Deadly Device is a recommended addition for anyone who enjoys a little exploring with their brainteasers and puzzles. There is no one set path through the environment, so you are often free to complete your objectives in any order.” --AllGame

“There are lots of puzzles in Nancy Drew and you can play the game on either Amateur Sleuth or Master Sleuth depending on how hard you want the game. To keep track of what you are doing you have a tasklist on screen and you can tick off anything you have done or ask for a hint if you are stuck... If you are after a more sedate game with nice voice work and story and some great puzzles Nancy Drew may be that game. ”-- InternetFreaks
