Recently I had a discussion with fizzbut and zunshiner in the comments section of a game (#670) about the way we use the keyboard to solve these puzzles and I'd like to follow it here.
Me, for example, while I'm right-handed, I use the keypad with my left hand and click on the cells with the right hand (on the mouse). This is a bit awkward but that's the position I'the comfortable in.
fizzbut, him, uses the number row keys, with a certain amount of efficiency since he is often the fastest.
And you all, how do you play ?
