13 Dec 09 Slot Machine Payout Percentages

slotmaschineOne of the most interesting academic discussions to have about slot machines is the discussion about payout percentages. There are two basic types of payout percentages associated with any gambling activity, the theoretical payout percentage and the actual payout percentage. The theoretical payout percentage is based on a player playing perfect strategy and represents the maximum yield based on the game underlying statistics that it could have. The actual payout percentage is compiled through empirical data by taking the amount of money the house wins and comparing it to the amount of money the house loses in order to compute a percentage of money that the house returns to the player for each particular game.

For slot machines, there are many slot machines where the theoretical and actual payout percentages are identical. These would be single pay line slot machines with a one coin maximum, otherwise known as the classic one-armed bandits. The reason that the two payout percentages are identical for this slot machine type is that there are no user choices in the actual game. You simply put your money in and spin the reels. This means that over the long run, the actual and theoretical payout percentages will converge and for practical terms will remain identical to each other.

For the next class up of slot machine, things are a little bit different. This would be the second version of the one-armed bandit where the player has a choice of betting one, two or three coins per spin. Since the best odds are always going to be present at the top coinage amounts regardless of the class of slot machine being played, players can actually end up giving themselves worse than normal odds by playing less than three coins per spin. This means that the theoretical payout percentage could be based on the three coin maximum, but if most players on the machine play less than three coins per spin the actual payout percentage could be quite a bit lower than that. For these types of slot machines, it is not uncommon to have a theoretical payout percentage in excess of 99% and an actual payout percentage in the 95% to 96% range.

The same is true for the new age video slot machines where there are dozens of different pay lines available. Payout percentages in the theoretical range could still be in the 99% plus range while people playing far less than the maximum number of pay lines (and therefore far less than the maximum number of coins) could bring the actual payout percentage down below 95%. These differences represent real money being lost and won and that is why knowing the difference between theoretical and actual payout percentages for slot machines is important.

23 Nov 09 Blackjack Strategy- How Dealer Bust Percentage Affect

Europa-CasinoWhat is “Going Bust?”

When a player, or the dealer, goes bust in blackjack, it means that they have reached a total hand value of over 21 points. Players immediately lose the hand when they go bust, and will lose their bet to the house. If the dealer goes bust, and the player did not, the player will win the hand. If both the dealer and the player both go bust, the house will still take the player’s bet.

What is the Dealer’s Bust Percentage?

The dealer bust percentage is the likely percentage showing how often the dealer is likely to go bust when showing specific cards. Although players will only know the dealer’s card that is face-up, they will be able to make an educated choice as to how to proceed with their betting by seeing the dealer’s card, and the two cards they have in their own blackjack hand.

Basic Blackjack Strategy and the Dealer’s Bust Percentages

Basic blackjack strategy is based on simple mathematical principles. By following these basic principles, players are able to substantially reduce the online casino’s house edge. When coupling basic blackjack strategy with information gathered about the dealer’s bust percentage, as well as looking at their own cards, players will have a better idea as to when they should hit, stand, or double down. This helps players to reduce the online casino’s house edge even further, giving them the best chance of coming out as winners.

Most Likely Dealer Bust Card Values

The most likely bust card values that the dealer will hold are the 5, the 6, and the 4. As far as the dealer is concerned, holding one of these cards is the worst kind of hand, since the likelihood of going bust is greater than with other cards. There is a 42% chance of going bust with either the 5 or the 6, and a 40% chance of going bust with the 4. When the dealer shows one of these card values, it is a good time for the player to double down if they are holding a good hand.

Least Likely Dealer Bust Card Values

The least likely bust card values that the dealer will hold are the 9, the 10 and the Ace.
