We posed this query to Frugal Vegas blogger Jean Scott, who responded thusly:
This turned out to be not an easy question to answer, although I have been a long-time player at Caesars properties and thought I was pretty knowledgeable about the Total Rewards program. However, my experience has been with machine play only: I not only haven't played table games in CET casinos, but it turned out that I didn't know any serious table game players, either.
So, the first thing I did, as I usually do when I need casino information, was to check the Total Rewards website where, as expected, I easily found the detailed information I already knew regarding how to earn Reward and Tier Credits for machine play. I was surprised to see, however, that there were no equivalent specifics for table games, nor other casino games (poker, sports betting, etc.). Here is the sum total of information I found regarding how to earn points from gambling:
In light of this vagueness, I visited an online chat forum to see if I could get some first-hand input from CET table game players. I heard from craps, poker, and blackjack players – and even a keno player – and most complained that there were too many factors involved -- not just the ones mentioned above -- plus there was no company-wide standard: It varies from casino to casino and even from one pit boss to another, since human discretion is involved. One knowledgeable player responded, "Earning on table games is not as transparent as it is on machines. I actually switched to VP as my main game specifically for the ease of predicting points and the speed at which they accrue."
In short, the consensus was that racking up credits any way, except playing machines, was a very slow process and inaccurate science that obliges you to risk a lot more money to get to the same tier level. If anyone reading this would care to share their personal experiences, feel free to write in and we'll include your empirical feedback as an "Update" to today's answer.
