Abstract

Abstract A visual system illustrates how many identical numerical sums turn up when two numbered dice are rolled out and how the identical numerical sums are visually differentiated, one from the other, by coding each of six numbered faces of a first die and by not coding any of the six numbered faces of a companion neutral second die. Thirty-six possible numerical sums are established when each of the six numbered and coded faces of the first die is oriented on a horizontal axis of a grid and when each of the six numbered faces of the companion neutral second die is oriented on the vertical axis of the grid. Within the thirty-six numerical sums, exists nine separate collective groups of sums, ranging in group values from three to eleven, wherein the identical sums within each collective group are visually differentiated, one from the other. The system affords a practical basis to create a variety of new dice related games, incorporating game boards, playing cards or a combination thereof.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 174 words
A pair of multi-sided dice, comprising one neutral die having thereon a plurality of flat faces of equal area, all of said faces provided with the same background indicia, each face additionally carrying means representing a numeral, said represented numerals being different, said represented numerals further being consecutive in ascending order, commencing with the represented numeral one; and one coded die having thereon the same number of flat faces as said neutral die, each face of said coded die carrying means representing a different numeral, the numerals represented on said coded die faces being the same, as those on said neutral die faces, and each face on said coded die carrying additional indicia, different from that on each other face and different from said background indicia on said neutral die; whereby the result of a throw of the pair of dice can be read by a combination of said additional indicia on the upper face of said coded die and the sum of the represented numerals appearing on the upper face of each die.
Claim 2
Dependent Claim 174 words
A pair of multi-sided dice, comprising one neutral die having thereon a plurality of flat faces of equal area, all of said faces provided with the same background indicia, each face additionally carrying means representing a numeral, said represented numerals being different, said represented numerals further being consecutive in ascending order, commencing with the represented numeral one; and one coded die having thereon the same number of flat faces as said neutral die, each face of said coded die carrying means representing a different numeral, the numerals represented on said coded die faces being the same, as those on said neutral die faces, and each face on said coded die carrying additional indicia, different from that on each other face and different from said background indicia on said neutral die; whereby the result of a throw of the pair of dice can be read by a combination of said additional indicia on the upper face of said coded die and the sum of the represented numerals appearing on the upper face of each die.
Claim 3
Dependent Claim 42 words
The pair of multi-sided dice described in claim 1, combined with a game board, upon which each visually differentiated numerical sum rolled out by the dice pair is displayed, thus constituting an apparatus, whereby a variety of different games can be played.
