This was so cute!! I bought this almost 2 years ago and finally got around to doing it, and we loved it!! My kids are 8 and 10, and it's probably more age-appropriate for their level now, my 10 year old crushed it (he could have probably done it at 8 though), my 8 year old was slower to decode things but that was expected, I printed out two of every clue so they could each do it on their own timeline. I did hide the clues and then created a sheet with clues to find the clues first, I wasn't sure how to hide them and for them to find it in order, but looking back I guess the order didn't matter too much. But it was so great, we will buy more!!
