ShopTo came out swinging with a great deal for Rooms: The Main Building earlier this month, but have now slashed their price to an attractive sub-tenner level. If you're a fan of sliding puzzles and room escape games, this will probably be right up your street, and there's a surprising amount of depth to be found throughout the hundred stages. Well worth a punt for puzzle aficionados.
There are over a hundred rooms to make your way through in this one, which you'll need to do by sliding pieces of them around until you can reach the exit. It sounds remarkably simple and to be honest it is, but there are a few tools at your disposal to help you along your way including teleporters and wardrobes. You can grab a copy of the game for £12.85, which is over £2 cheaper than the next best offers coming in from Amazon and HMV.
