My husband and I love Finders Seekers night! We can't wait to tear the box open and dive in. The box is designed as a "one time use" game, but we pass it on to our 10 year old when we are done. I don't know which we love more, solving the clues and catching the culprit ourselves, or watching her walk through the challenges afterward.
There's a nice mix of hands on and online puzzle solving. The mysteries are not complex enough to require Sherlock Holmes level detective work, but they are challenging enough to make you want to click the "hint" button from time to time.
