# 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.

Casino Words™ Not Casino Words™
SUCCESS FAIL
GRACE FAVOUR
SWAY STAND
ARGUE DISPUTE
RUSSIAN AMERICAN
OFF ON
PRICELESS WORTHLESS
UGLY BEAUTIFUL
LINEAR NONLINEAR

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
