In (75) I said of the application || usage of the word “game” that it is not “ || ‘bounded || limited at every point by rules” || ’; but what does a game look like that || which is bounded at every point by rules? Whose rules let no doubt penetrate; || The rules of which don't let in any doubt, stop all the holes for it || up all the holes? – Can't we think of || imagine a rule which regulates the application of the || a rules || rule? || ; and a doubt which that rule removes, – and so forth?
     But that || this is not to say || doesn't mean that we are in doubt, – || – because we can imagine a doubt. I can well imagine that someone is always in doubt before he opens the door of his house || before he opens the door of his house is always in doubt as to whether a chasm may not have opened on the other side of it; and that he makes certain about it || of it before he steps through the door (and it may sometime || one day it may prove that he was right); but I am not, therefore, in doubt in a similar case myself. || myself in doubt in a similar case.
