Ask The Wizard #178
Recently, I came across some statistics detailing the house advantage in Baccarat (Banker=1.17%; Player=1.36%). However, these figures did not account for tie bets, which raises some questions for me. I have seen similar numbers in various references, but I can't recall their specifics. My main concern is: why would calculations exclude the tie wager? Is there a rationale behind this approach that I'm missing? This seems like a questionable way to convey the house's advantage. How can I effectively illustrate the flaws in this method, assuming it is, in fact, erroneous?
The variation in reported house edges for Baccarat often stems from differing definitions of the concept itself. Personally, I interpret the house edge as the expected casino profit divided by the original bet. Other writers in the gambling community may calculate it as the expected casino winnings relative to the resolved bets. The key distinction lies in whether or not ties are factored into the outcomes. In an eight-deck game, the probabilities in Baccarat are as follows:
- Banker wins: 45.8597%
- Player wins: 44.6274%
- Tie wins: 9.5156%
I approach the calculation of the expected return on individual bets by including tie outcomes in my assessment.
- Banker: 0.458597*0.95 + 0.446274*-1 + 0.095156*0 = -0.010579
- Player: 0.458597*-1 + 0.446274*1 + 0.095156*0 = -0.012351
- Tie: 0.458597*-1 + 0.446274*-1 + 0.095156*8 = -0.143596
This leads me to determine a house edge of 1.24% for the player, 1.06% for the banker, and a whopping 14.36% for the tie.
Some gambling authors prefer to disregard ties as if they were nonexistent, postponing the resolution of those bets. In this scenario, the probability of a banker or player winning combines to 90.4844%. Consequently, the odds of the next resolved bet resulting in a player win stand at 49.3175%, while a banker win is at 50.6825%.
In computing the expected return for the player's bet, the other perspective calculates it as 49.3175% * 1 + 50.6825% * -1 = -1.3650%. For the banker bet, disregarding ties yields an expected return of 49.3175% * -1 + 50.6825% * 0.95 = -1.1692%. Thus, when ignoring ties, the house edge is 1.36% for the player and 1.17% for the banker.
I advocate for including ties in calculations because it offers players a true reflection of their anticipated losses over time. For instance, if a player wagers $100 on the banker in Baccarat over a four-hour period, with an average rate of play of 80 hands hourly, the expected loss would be calculated as follows: $100 * 4 * 80 * 0.0106 = $339.20. There's no need to factor ties into this equation. If a casino were to utilize the 1.17% house edge for bankers, it would lead to an inflated expectation of player loss and potentially mislead the player.
Another reason I incorporate ties in my calculations is that leading experts in blackjack and video poker factor in ties when analyzing those games. For instance, disregarding ties in a 9/6 Jacks or Better game would inaccurately suggest that the return is just 99.4193% when hitting a pair of jacks or higher. However, the consensus among experts is that the correct return, with optimal play, is actually 99.5439%.
Lastly, I’m sharing a table containing statistics from various gambling literature regarding baccarat.

I think this might pique your interest. I frequently use Betfair while in the UK. If you’re from the U.S., you might find it is not permitted due to various regulations, but if you’re not aware of it, head to betfair.co.uk. It's a betting exchange, distinct from traditional bookmakers. My inquiry is this: they are now offering a version of roulette that has NO ZERO—this is quite genuine. Can you conceive a solid strategy for this game, or would you prefer to keep it private? Best regards, Jonathan. P.S. They have other casino games with no house edge, too.
I attempted to register for an account to explore this, but they restrict access for U.S. players. I believe the minimum wager is £2 while the maximum is £50. Even in a no house edge scenario like this zero-zero roulette, no betting system can ultimately yield returns outside of that 0% benchmark. Regardless of strategies employed, the more bets you place, the closer the actual house win will approach 0%.
I frequently play at Bodog via Neteller. Do you happen to know if they have contingency plans in place for deposits and withdrawals if Neteller or other services cease supporting U.S. players? A check won’t be useful if banks won’t honor it.
I have dealt with numerous foreign checks from online casinos that never arrived on official casino letterhead. Often, they appeared more akin to generic money orders, rendering it hard to identify the issuer immediately. Should the situation arise, I believe Bodog would likely employ a nominal check or money order that banks would struggle to trace back. Additionally, I don’t foresee Neteller disappearing any time soon.
I was sitting at a pai-gow poker table in Las Vegas last week when another player, frustrated with his losses to the dealer, chose to bank the following hand. After the cards were dealt, he promptly began setting his hand without waiting for me. I cautioned him that this was unwise, as I could potentially see his cards before finalizing my own hand. I also mentioned that this might not even be permissible. The dealer just affirmed that it was acceptable since it only impacted his own standing. I refrained from looking at his hand, but I could have modified my play to improve my position. This brings two questions to mind.
Is a banker obligated to wait until the other players have completed setting their hands before finalizing their own?
And if they don’t follow this protocol, is it considered improper etiquette to exploit this information for one's own advantage? It feels wrong, akin to spying on the banker’s hand.
In the casinos in Vegas, they typically ensure the cards are tucked below your bet when you are banking, disallowing any early contact until others are done setting hands. If you attempt to sneak a glance beforehand, the dealer tends to react promptly to discourage it. However, in your establishment, I wouldn’t hesitate to sneak a peek if I noticed the banker setting their hand prematurely. Just be cautious, as it’s comparable to a dealer in blackjack unwittingly revealing their hole card. This provides valuable insight, and it’s entirely legal to use.
In Oklahoma, we frequent the Indian casinos, and I’ve come to understand that we are essentially playing bingo. If this is the case, do these machines offer payout rates comparable to those equipped with random number generators in Vegas?
That is indeed correct. In states like Oklahoma, traditional \"class 3\" slot machines are regarded as illegal. To circumvent this, certain establishments implement machines that randomly select bingo cards and balls. Winning patterns correlate with certain payouts and are presented to players akin to slot machine results. If executed correctly—though they often aren’t—the games would play similarly to those in Vegas. I recall spotting popular Williams slots like Reel 'em In during my visit to a Tulsa casino, which incorporated a small bingo card in the corner of the screen. Otherwise, they appeared identical to standard machines. I’m not aware of what return rates they’re programmed to in Oklahoma, so I can’t provide insight on that matter.
Imagine five individuals are gathered in a room. What are the odds that at least two of them share the same birth month?
To simplify, let’s assume each person has an equal 1/12 chance of being born in any month. The probability that all five individuals are born in distinct months is calculated as (11/12) * (10/12) * (9/12) * (8/12) = 0.381944. Therefore, the likelihood of at least two individuals sharing a birth month would be 1 - 0.381944 = 0.618056.

I've just returned from a gambling excursion to Niagara Falls, Ontario. Interestingly, Casino Niagara features a Mini-Baccarat table (with nine seats) where the banker wager is rounded down to the closest $20 before calculating the commission. Thus, a $35 winning wager results in only a $1 commission being charged. This places the commission percentage for that bet at 2.86%! If I’m not mistaken, isn’t this indicative of the absence of a house edge on bank wagers, and thus a player advantage? Do you concur?
As I mentioned previously, the probabilities in an eight-deck game of Baccarat are:
- Banker wins: 45.8597%
- Player wins: 44.6274%
- Tie wins: 9.5156%
Here, the expected value for a banker wager is computed as follows: 45.8597% * (1 - (1/35)) + 44.6274% * -1 = -0.00075. Consequently, the house maintains a 0.075% edge. The breakeven commission on the banker wager stands at 2.693%. If one were to bet $37.14, the odds would shift in your favor.
I have been together with my boyfriend for about six years, but I recently moved far away to pursue my education. He has been unfaithful with a girl known for her promiscuity. He claimed that he didn’t intend for it to escalate and was merely trying to make me jealous after I kissed another guy a couple of years ago. I genuinely love him and want to move past this, but he ended up having unprotected sex with her in an elevator. He seems truly sorry and filled with remorse. Should I aim to forgive him and proceed with our relationship, or am I potentially wasting my time?
Sex in an elevator? How is it that such events never occurred during my single days? It took a good six months of dating before I reached second base with anyone. As I’ve often pointed out, while forgiving infidelity the first time can be a choice, a second occurrence is a clear no-go. If you feel he is sincere and remorseful, you might be able to get through this, assuming he doesn't have any significant flaws.
My boyfriend confessed to cheating on me approximately four months ago, and we have been diligently working on our relationship since then. However, I find myself struggling with trust issues and am conflicted about whether my feelings are just paranoia or if there's genuine cause for concern. I’m unsure how to address my worries with him without inciting defensiveness, but I crave reassurance. What steps should I take?
I recommend not mentioning it at all. Doing so is unlikely to lead to any positive outcome and could potentially spark a significant disagreement. Ultimately, with time, you’ll find a way to move beyond this situation. Furthermore, this highlights the importance of ceasing any dishonest behavior if you find yourself in that position, but there’s no necessity to admit to it openly.
