A easy to learn little dice game that asks you to Think Twice before you re-roll your dice. The game shares some similarities with Yahtzee and Cosmic Wimpout. You get 3 rolls of 6 6-sided dice and one special category dice. If you use all of your dice, your score doubles. If your dice match your category (high, low, same, different, odd, even) then your score doubles again. Once this score is made, you may chose to roll the Multiplier Dice. The Multiplier Dice will come up with 1,2,or 3 this number is multiplied by your current score, but be careful, the multiplier die also has a 0. - BoardGameGeek
