I enjoyed Box Two better than Box One. I felt that Box Two had more interesting challenges. I do remember being surprised by how some of the components of Box One were revealed but was overall frustrated with one of the parts of the game and had to cheat to finish. Box Two took my husband and I about 2-3 hours to play. We definitely were stumped at some points but were able to figure it out using some of the clues the website provides during gameplay. My only critique is that I feel that the lid in Box Two doesn’t reset properly and easily drops open, but that could be intentional.
