In the end, I couldn’t solve everything. It took me about three hours to work my way through What’s the Password?, and I completed about 77 percent of the puzzles. But the game reminded me of the value of patience and a good night’s sleep; coming back in the morning with a fresh mind and coffee in hand, I usually had an easier time figuring things out. A lot of the fun of What’s the Password? was seeing what unexpected format would be thrown at me next, and that’s what gives the simple premise such depth.
