The absolutely essential The Room goes free on iPad
It's all about solving puzzles, fiddling with mechanisms, and looking through a magic eyepiece to crack open a mysterious puzzle box.
Back when it was released, we said "while point-and-click fans will love every second, The Room is good enough to convert all but the most stringent naysayers to its cause".
Then get the sequel, and the third game too. They're all brilliant.
And if you get stuck, we've got a complete walkthrough for the entire game. Start with Chapter 1, here.
The Room will go back to its original price in three weeks.
