Whew, beware of becoming a rules lawyer, my friend.

My rule of thumb is:
You own the game, play it the way you want in solitaire, and discuss/decide how you and your opponent want to play when you're in face-to-face, or online in shared encounters.

Shared play makes this fiddly kid's game much more fun to spend time playing.
