Sic Bo Sic Bo. Sicbo Australia Sicbo Australia. Spanish 21 Spanish The set of the optimal plays for all possible hands is known as " basic strategy " and is highly dependent on the specific rules and even the number of decks used.
Good blackjack and Spanish 21 games have house edges below 0. Traditionally, the majority of casinos have refused to reveal the house edge information for their slots games and due to the unknown number of symbols and weightings of the reels, in most cases this is much more difficult to calculate than for other casino games.
However, due to some online properties revealing this information and some independent research conducted by Michael Shackleford in the offline sector, this pattern is slowly changing.
The luck factor in a casino game is quantified using standard deviations SD. The binomial distribution assumes a result of 1 unit for a win, and 0 units for a loss, rather than -1 units for a loss, which doubles the range of possible outcomes.
Furthermore, if we flat bet at 10 units per round instead of 1 unit, the range of possible outcomes increases 10 fold. After 10 rounds, the expected loss will be 10 x 1 x 5.
As you can see, standard deviation is many times the magnitude of the expected loss. The standard deviation for pai gow poker is the lowest out of all common casinos.
Many, particularly slots, have extremely high standard deviations. As the size of the potential payouts increase, so does the standard deviation.
As the number of rounds increases, eventually, the expected loss will exceed the standard deviation, many times over. From the formula, we can see the standard deviation is proportional to the square root of the number of rounds played, while the expected loss is proportional to the number of rounds played.
As the number of rounds increases, the expected loss increases at a much faster rate. This is why it is impossible for a gambler to win in the long term.
It is the high ratio of short-term standard deviation to expected loss that fools gamblers into thinking that they can win.
It is important for a casino to know both the house edge and variance for all of their games. The house edge tells them what kind of profit they will make as percentage of turnover, and the variance tells them how much they need in the way of cash reserves.
The mathematicians and computer programmers that do this kind of work are called gaming mathematicians and gaming analysts.
Casinos do not have in-house expertise in this field, so outsource their requirements to experts in the gaming analysis field. From Wikipedia, the free encyclopedia.
