# What is a Casino Word™?

This is in the spirit of the What is a Word/Phrase™ series started by JLee with a special brand of Phrase™ and Word™ puzzles.

If a word conforms to a special rule, I call it a Casino Word™.
Use the following examples below to find the rule.

$$% set Title text. (spaces around the text ARE important; do not remove.) % increase Pad value only if your entries are longer than the title bar. % \def\Pad{\P{0.0}} \def\Title{\textbf{ Casino }} % \def\S#1#2{\Space{#1}{20px}{#2px}}\def\P#1{\V{#1em}}\def\V#1{\S{#1}{9}} \def\T{\Title\textbf{Words}^{\;\!™}\Pad}\def\NT{\Pad\textbf{Not}\T\ }\displaystyle \smash{\lower{29px}\bbox[yellow]{\phantom{\rlap{rubio.2019.05.15}\S{6px}{0} \begin{array}{cc}\Pad\T&\NT\\\end{array}}}}\atop\def\V#1{\S{#1}{5}} \begin{array}{|c|c|}\hline\Pad\T&\NT\\\hline % \text{ SUCCESS }&\text{ FAIL }\\ \hline \text{ GRACE }&\text{ FAVOUR }\\ \hline \text{ SWAY }&\text{ STAND }\\ \hline \text{ ARGUE }&\text{ DISPUTE }\\ \hline \text{ ZOOM }&\text{ ADJUST }\\ \hline \text{ RUSSIAN }&\text{ AMERICAN }\\ \hline \text{ OFF }&\text{ ON }\\ \hline \text{ PRICELESS }&\text{ WORTHLESS }\\ \hline \text{ UGLY }&\text{ BEAUTIFUL }\\ \hline \text{ LINEAR }&\text{ NONLINEAR }\\ \hline \end{array}$$

And, if you want to analyze, here is a CSV version:

SUCCESS,FAIL
GRACE,FAVOUR
SWAY,STAND
ARGUE,DISPUTE
RUSSIAN,AMERICAN
OFF,ON
PRICELESS,WORTHLESS
UGLY,BEAUTIFUL

I think a Casino Word has the property that

If we convert each letter to its corresponding position in the alphabet (A=1, B=2,..., Z=26) then a Casino word consists entirely of red Roulette numbers or entirely of black Roulette numbers.

Examples

$$SUCCESS \rightarrow (19,21,3,3,5,19,19)$$.
All of the numbers in brackets are red Roulette numbers. Hence, this is a Casino Word.
$$ZOOM \rightarrow (26, 15, 15, 13)$$
All of the numbers in brackets are black Roulette numbers. Hence, this is a Casino Word.
$$STAND \rightarrow (19,20,1,14,4)$$
This word contains a mix of red and black numbers, hence is not a Casino Word
