It's called Casino Marketing 101 .... no different than a retail store having a different profit margin on most items in the store. We learn in marketing courses that the most profitable items are at the end of the aisles and also at eye level, and that the best buys can be found on the bottom row .... same in a casino, usually the back row of tables, or at least not the main corner aisle table.
Sun Tzu gives us 2 valuable lessons in The Art of War. One is in “the Nine Situations”, that if you manage to seize a favorable position, the amount of information that we choose to disclose should be limited ….. thus we cannot disclose on a public forum all we know on how to combat the biased dice that casinos are using because they would simply just make countermeasures.
Second, Sun Tzu tells us that:
The Gambler's Book Shop in Las Vegas motto is "knowledge is protection." At the store, they have a book by Steven L. Forte for $750.00 called “Casino Game Protection: A Comprehensive Guide” ….. you can also get it on Amazon from about $300. to $1,000.
As explained on this website, there are no technical dice specification laws in Nevada and Forte states in his aforementioned book on page 247:
This vagueness in the Nevada dice laws allows the casinos to have an unfair game and increase the House edge as much as they desire --- just like they did when they started using 6:5 BlackJack to increase the House edge by over 800 percent (see http://www.blackjack-scams.com/html/6_5_blackjack.html )
.... many still think that is ridiculous !!
