I came on “The Room” series by accident when my attention was called to The Room Old Sins, which is actually the 4th in the series. I started with this one, The Room, because it was first, and you can try it for free for the first level to see if you like it. If you do, you can finish the rest of the game for .99. After finishing this, I immediately signed on for #2, and have now completed it. If complex puzzles, logic, gadgets, gizmos, unexpected turns and the occasional red herring are your thing, you have arrived. I say this, and not lightly; these games are FLAWLESSLY executed. They are challenging without being impossible; and hints are provided, if you want to use them, that give you an increasing degree of guidance to get you through any difficult spots. I’m a senior citizen, and I have hooked my wife, my mid-30’s daughter and my teenage grandson on The Door. Fun for all ages. The graphics are outstanding, the music totally right and the atmosphere perfect. The fee is small for several hours of enjoyment, and after the first one, a purchased game will support multiple profiles. No ads. No nonsense. Just some seriously challenging fun!
