Etruscan numerals whether the numbers on opposite faces of Etruscan dice add up to seven, like nowadays. Some dice found did not show this proposed pattern. An aspect of the Etruscan numeral system is that some numbers, as in the Roman system, are represented as partial subtractions. So "17" is not written *"semφ-śar" as users of the Arabic numerals might reason. One instead finds "ci-em zaθrum", literally "three from twenty". The numbers 17, 18 and 19 are all written in this way. The general agreement among Etruscologists nowadays is the following (except about which of huθ and śa were "four" or "six",
Miwin's dice the different game variants. All the games need only 3 dice, in comparison to other theoretical nontransitive dice, designed in view of mathematics, such as Efron's dice. The probability for a given number with all 3 dice is 11/36, for a given rolled double is 1/36, for any rolled double 1/4. The probability to obtain a rolled double is only 50% compared to normal dice. Removing the common dots of Miwin's Dice reverses intransitivity. Miwin's dice facilitate generating numbers at random, within a given range, such that each included number is equally-likely to occur. In order to obtain a range
