Crapless Craps, a game that has existed for more than 20 years, is a
modification of standard craps designed to eliminate the possibility of
the pass line bettor losing on the come-out roll. However, it has several
serious drawbacks that have prevented it from achieving significant
popularity with the gambling public. No-Crap Craps is a modification of
Crapless Craps created to overcome these shortcomings. This aim is
achieved by regarding every number except 7 as a point number, but with
numbers 2 and 3 grouped together as 2-or-3, and numbers 11 and 12 grouped
together as 11-or-12. When betting against the shooter, a seven-out after
point 11-or-12 pays half. The result is that the house advantages of the
pass line bet and the don't pass bet are exactly those of standard craps.
