I personally opt to include ties although I respect the other definition. The rationale is that if a bet isn’t resolved then it should be ignored. Many other sources do not count ties in the house edge calculation, especially for the Don’t Pass bet in craps and the banker and player bets in baccarat. If one wants to compare one game against another I believe it is better to look at the ratio of money lost to money wagered, which would show Caribbean stud poker to be a much better gamble than roulette. The player only looking at the house edge may be indifferent between roulette and Caribbean stud poker, based only the house edge. However the ratio of average money lost to average money wagered in Caribbean stud is only 2.56%. In Caribbean stud poker, for example, the house edge is 5.22%, which is close to that of double zero roulette at 5.26%. However the statistic is very biased as a measure of risk. The conventional definition can be helpful for players determine how much it will cost them to play, given the information they already know. Most players are not going to know how much their average wager will be in games like blackjack relative to the original wager, thus any statistic based on the average wager would be difficult to apply to real life questions. For example if a player knows the house edge in blackjack is 0.6% he can assume that for every $10 wager original wager he makes he will lose 6 cents on the average. The reason that the house edge is relative to the original wager, not the average wager, is that it makes it easier for the player to estimate how much they will lose. While this can vary, the standard deviation on slot machines are very high. Slot machine standard deviation based on just one machine.Slot machine range is based on available returns from a major manufacturer.Standard deviation depends on bet made.Assuming player plays the house way, playing one on one against dealer, and half of bets made are as banker.Las Vegas single deck rules are dealer hits on soft 17, player may double on any two cards, player may not double after splitting, one card to split aces, no surrender.
