just been playing with the monolply/yahtzee/boggle game and i've been trying to work out how to get a decent score in yahztee. the rules say to get the bonus in the top section you need 63+ points - sorted. how do i get a yahtzee bonus though? i've rolled up to 3 yahtzees in the same game and it's not given me this bonus. the first one went in the yahtzee box for 50 points - the next ones in the top section. i've been playing by myself and no against a computer or other person - does this make a difference? really need to work out how to get a yahtzee bonus as the top score is unbeatable without it.
