Search for clues and investigate real declassified UFO cases to find the truth!

Project Blue Book The Game: Hidden Mysteries is the official, free-to-play, hidden object adventure game based on HISTORY’s hit drama series PROJECT BLUE BOOK, created by David O'Leary, and executive produced by Academy Award and Golden Globe® winner Robert Zemeckis. The series explores the historical, Top Secret investigations into UFOs conducted by the U.S. Air Force between 1952 and 1969. 

In Project Blue Book The Game: Hidden Mysteries, you will start off as a newly recruited agent in Project Blue Book during the 1950s, under the guidance of the show's lead investigators, Dr. J. Allen Hynek (played by Aidan Gillen from “Game Of Thrones”), and Captain Michael Quinn (played by Michael Malarkey from “The Vampire Diaries”), and begin to investigate real declassified UFO investigations to find the truth! 

Hundreds of puzzles, witness interviews and hidden object scenes will challenge your observation and deduction tactics as you investigate alongside your favorite characters into many of the cases you loved from the series, uncover exclusive new content, and explore new cases that can only be found in the game! The game's story is written by bestselling science-fiction writer and award-winning game writer Steven-Elliot Altman, best known for similar social games like PEARL’S PERIL and ANCIENT ALIENS.

We're here to find the truth! So, come help us investigate flying saucers along with Dr. Hynek in the world's first Unidentified Flying (Hidden) Object Game!

High quality game with lots of story polish

Project Blue Book is, at its core, a hidden object game, but it is very successful at connecting the items in each level to the story elements and weaving in a lot of dialog, clues and other mini games.
The visuals are beautiful and it’s all cohesive so you feel like you are in that late 1940s to early 1950s era, and it’s reinforced all over the game. I haven’t gotten that far in yet, but I can already see based on the main screen that there are tons of locations and perhaps more game types.
There aren’t many games with Robert Zeneckis’ name on it and the quality seems much higher than other hidden object games I played.

Addictive fun - Updated and improved

Earlier versions had a few issues, but as far as I can tell they've been corrected. The addition of daily quests lets you earn more coins for buying things with, and the ability to play the various mini-games on demand is a welcome improvement. The core of the game is still the hidden object challenges, and having the scoreboard for each scene encourages you to keep trying to beat your previous best score and climb to a higher ranking, but if you get tired of hunting for hidden objects then you can play one or more of the mini-games.

Hello! Thank you for your review. We are aware of those issues now and are working on them. You've been a great help going into detail about what wasn't working in our game. Regarding more content we hope the next case will be available within a month.

As Amazing As The Series

This game is just amazing, it takes us back to season one of the series. The puzzles are amazing and really make you think. I’m looking forward to playing more of the game when it unlocks. If you love the television series you will love this game. I’m a huge fan of the series and I’m a huge fan of the game. You have to play this game.

Now I will say during my play through so far I’ve noticed some bugs/glitches happen but any game will have those minor issues and they didn’t last long so don’t worry too much about it.

Hi! Glad to hear you enjoy the game. We try to fix any bugs/glitches when we encounter them and are constantly working on improving the game. Thank you so much for your review.
