Changes in the New Jersey Dice Laws ...

1.  In the 1980's the New Jerseys Dice laws included the following section that is no longer in the current Dice laws:

19:46-1.15 Dice; physical characteristics
(a) Each die used in gaming at Craps shall:
...
2. Be manufactured to an accuracy tolerance of no greater than .0002 of an inch;

 See citation on Page 442 in http://njlegallib.rutgers.edu/legallib/njar/v05/p0439.pdf 

The current NJ Dice regulations do not include this technical specification:

See http://www.state.nj.us/casinos/actreg/reg/docs_chapter46/c46s01sec15to19b.pdf

Why has this accuracy tolerance been removed ??!!

2.  The most important dice rule is in 19:46-1.15(a)6. (old 7. ):

19:46-1.15  Dice; physical characteristics

          (a)  Except as otherwise provided in (b) below, each die used in gaming shall:
6.       Have its weight equally distributed throughout the cube and no side of the cube heavier or lighter than any other side of the cube;

We find that this rule 19:46-1.15(a)6. is rarely followed or enforced in New Jersey.  Remember that these dice specifications do not even exist in Nevada.
