Pat, we play most of the words with the two of us sitting in front of the desktop computer. One of us enters the words that either of us think of. In the hours that follow, one or other of us may go back to open puzzles to try to think of some more words. And, as people have said in
another recent thread, an additional word can pop into one's mind at any time and place.
I'm not sure if having two players has much impact on our final score because, after playing together for so many years, we tend to think of the same words as each other. It does mean we probably progress faster than most other players, until we run out of steam.
