My husband and I tried this. We didn't feel like we were doing this together. You need to be online while doing this. So I was on my phone and he was on his. I would have preferred if you could do this with just the items in the box.
This mystery box was okay, but we really disliked that there was so much online research and it was far less focused on logic puzzles and critical thinking. There was also no real through-story to the boxes we received, and it seemed that the makers just picked a place as a theme, rather than for any context of a story. I can see how families with smaller children would get a lot more value out of this subscription, but it isn't for us.
My first box was, to say the least, underwhelming! It came with a poster, sheets of paper, a foam hockey puck, and bottle caps then told me to start the mystery online. Belch! Oh I see, no cool relics, no ascetics of wonderment. Bland! The child in me wanted something magical but instead, opened a clunky box that lacked imagination. The creative department/creative storywriters need to have more emphasis on mystery, clues and relics. I grew up with puzzle boxes, educational games and mystery/spy books. I am this demographic. This box seems like a simpletons answer to a puzzle box. I hope they step it up and I'll be looking for a box that has more intrigue.
