Yahtzee is a family tradition in my house. One time there was a dispute over whether you can fill in 40 for ‘large straight’ if you roll a ‘Yahtzee’ after you’ve already crossed off ‘Yahtzee’ and you have the top filled in. (You can.) It never evolved into a knife fight, however.
I like the game, too. Never had to slice anyone up though.
Don’t you mean a Full House ? A Yahtzee could be construed as two-of-a-kind plus three-of-a-kind, but I don’t see how it could be construed as a Large Straight, which is one thru five or two thru six.
The Joker rule allows 5-of-a-kind to be scored in any section of the bottom provided that both Yahtzee and the top-section square corresponding to the rolled number have both filled in. I thought the Joker option only applied when Yahtzee was filled in with 50, though--not when it's defaulted with zero.
I rather liked a Macintosh version which would allow 5-of-a-kind to be filled in any top-section square if the one corresponding to the roll was already filled (e.g. if I've filled in fives for 15, and then later roll 5 fives, then if I haven't scored aces (1's) yet I could score the roll there for 25 points. A very nice ability. The option was available whether or not Yahtzee was filled in, and could create some interesting strategic twists.
