doubling cube should keep Dice Poker simple ...
but without a bonus this game is missing very important feature. there is a book about Yahtzee strategy called "Advantage Yahtzee" ... check it out on Amazon.com. I have this book, it's very interesting for Yahtzee players. Bonus makes this game very exciting and without it we miss
huge portion of the flavor. Doubling cube would substitute this lacking excitement.
Tripple Yathzee is a different spiece. It's a very complicated game and there is no need for any doubling cube at all.
