So, you can pick any sentence/sentences from the Dark Tower series. One sentence is the minimum. The game will be much more enjoyable if we try to give sentences with some real meaning. If someone chooses the line: "he said" - it won't give us much fun.
So one gives a random line or random lines from the series and the others must find out from which book it is/they are from.
BUT
you can guess only 3 times (all together) - I mean for one quote only 3 guesses can be given: from one person or from 3. If the third guess is wrong the one who gave the line can give a new one. (It would be way too easy if we could guess as many times as we want.)
So
you give a line (or more)
and the others have only 3 shots to find out where it is from.
First one:
"Roland, who held this secret in his own counsel until it seemed more complex than it really was, was surprised at how quickly and simply it was told. And Eddie, he saw, wasn't completely surprised."
