A Yahtzee like game where there are 5 hollow, transparent, six-sided dice. Within each is another smaller die. You get three rolls and get to keep any number of dice on each roll, just like Yahtzee. You then score based on 13 categories. Categories are Ones, Twos, Threes, Fours, Fives, Sixes, Odds, Evens, Lo In/Hi Out, Hi In/Lo Out, Lucky 7-11, One Away, Double Dice.
An example of scoring is Lo In/Hi Out: After the third roll, total all the Double Dice (both inner and outer) that have a lower number on the inner die and a higher number on the outer die. If all 5 Double Dice are Lo In/Hi Out, total all dice and DOUBLE the score!
