Customer Reviews
Hidden Expedition: Smithsonian Castle is rated 4.1 out of 5 by 27.
Rated 5 out of 5 by from Totally enjoyed this unique game Although the game appeared to be short it was because I was so caught up in it and couldn't stop playing. Very unique HOS and puzzles. The game has the option of setting your hint and skip to refresh quickly. I'll have to admit, I skipped several puzzles as I am not much of a puzzle player, but they were unique so puzzle nuts will enjoy them. Voice overs, color, animations and graphics were terrific and the storyline was different which is a change from the "horror" stories coming out lately. I did get a bit confused with some of the characters which always seems to happen when dealing with "time" changes for me. Transporter map was very good and needed as you did move around a bit. Highly recommended.

Rated 5 out of 5 by from Really FUN! This, by far, is the best game I have played in a long time. I have been on Big Fish games for years and certainly have played lots and lots of games, but I enjoyed this one so much that I ended up playing it again right after I played it the first time. I scored level of challenge as excellent but it certainly could have been harder, however I enjoy something that is not too difficult as I am playing to relax. I enjoyed the variety of puzzles/HOPs. This game made logical sense in all ways and was just FUN!! I think there was a glitch on one of the HOP's in the "extras" section. I could finish it in 46 seconds with only touching the items that were on the list - could only score a 50%, and therefore could not achieve gold medals in all HOPS. The game let you re-try over and over. On other HOPS I could eventually achieve 100% with practice. The one where you have 3 parts to make a triton I could not although I made no mistakes. Anyone else have that?

Rated 5 out of 5 by from I need a title? I just reactivated my account so I could play the demo; didn't want to wait until morning. And I was so glad. This is such a cool game. The Hidden Expedition games just get better and better. There are features in the puzzles in this one I haven't seen before.

Rated 5 out of 5 by from Great Game SE version is long and a lot of fun. I especially liked the clear graphics and design. The Smithsonian fact cards are always of interest. Some of the mini-games are new to me and the hidden objects are either interactive or unusual. There is a map. The hint button is helpful and can teleport you to the next place.

Rated 5 out of 5 by from Expiditious! This is an awesome game. Some puzzles were too easy, but the story and general searches were incredible.
