Hey, I don't know if you saw my comment on the Originality discussion, but I mentioned that Yatzy is actually a public domain game. The name "Yahtzee" is copyrighted by Hasbro, but they don't own the Yatzy game itself, like I said it's public domain. So you can actually publish it under the name "Yatzy"! It really isn't any different than making, say, checkers or chess in SmileBASIC.
