Streaks19 October 2008
Let's talk about streaks. Every casino gambler, from the best of them to the worst of them, knows that all casino contests are streaky. You win some, you lose some; you win a few in a row; you lose a few in a row. You have good days; you have bad days.
Streaks and gambling go together like a horse and a carriage, love and marriage, Belvedere and a martini. We all know this for a fact.
However, some gambling pundits pontificate that the good and bad streaks even out in the games - which is not the case in almost all casino games. Indeed, if you are a betting man or woman (And who else would be reading this article?) wager your money on the fact that the casino will have more "good" streaks for them (good meaning they win more decisions) than "bad" streaks against them. The players will face just the opposite situation. They will have more bad streaks and fewer good streaks.
The reason for this is in the nature of the games, which usually means the math of the games. Let's take a look at the casino players' favorite table game, blackjack. It is no secret that blackjack is a very close contest between the player and the casino — if (and this is a big IF) the player knows the correct basic strategy, the computer-derived best play of each player hand against every dealer's up card.
In most traditional blackjack games, the player using correct basic strategy will face an approximately one-half percent house edge, which means a loss of approximately 50 cents for every $100 the player wagers. That's a good game, pretty close.
However, blackjack is not the equivalent of flipping a coin where the player and the casino win half the hands and lose half the hands respectively. Absolutely not. The house will win approximately 48% of the hands; the player will win approximately 44% of the hands; and approximately 8% of the hands will be pushes (ties).
Clearly the house will have longer winning streaks and shorter losing streaks than the player because of these percentages. If there were no other betting options in a blackjack game, the player would lose $4 for every $100 he bet. Yet, the player does not lose this much; in fact, the player loses much less because blackjack has certain playing options that allow the player to get more money on the table in certain hands — he can double down on two cards; he can split; he can sometimes double down on his split hands; he might even be able to surrender his poor hands. A big benefit for the blackjack player is getting that 3-to-2 payout for a blackjack — with blackjacks appearing in about 5% of the hands.
These playing options bring the monetary edge of the casino down to that approximate one-half percent. Casinos that have instituted the 6-to-5 payout for blackjacks have therefore seriously hurt the players' chances of winning at the game by drastically increasing the house edge.
At roulette, the house is a solid favorite to have more winning streaks than losing streaks on the outside even-money proposition bets. On the red/black, odd/even, high/low propositions the house will win 20 decisions and lose 18 decisions. That translates into a 53% win rate for the house and a 47% win rate for the player. The house therefore is the favorite to have winning streaks, while the player is the favorite to have losing streaks.
On the center "straight up" wagers, the house wins 37 times and loses one time in 38 spins on average. Of course, no one would play the straight up wagers if the payout were 1-to-1 so the house pays 35 to one on these wagers. That brings the house edge down to 5.26%, which is fairly hefty. The only way the player can bring the winning and losing streaks even at roulette is to bet half of the numbers. Unfortunately, while betting 19 numbers at roulette is a 50-50 game in terms of streaks, the house still wins more money since the payoffs are shortened by that 5.26%.
Craps puts the house in a favorable streaking situation on its most popular bet, the pass line. The house wins 251 decisions, while the player wins 244 decisions on this wager. While this makes it a very close contest you can see the house will have slightly longer winning streaks than losing streaks.
As with roulette's straight up wagers, the proposition bets at craps are all long shots that pay less than their true odds. Take a bet such as the 12, known as boxcars, which has a one in 36 chance of appearing. Obviously, the player who bets the 12 each and every roll will find himself in enormous negative streaks. However when he hits this number, the house doesn't pay the win off at one-to-one as only the truly insane would then make such a bet. Instead, the house usually pays off at 30 to 1 - much less than the true odds of 35 to 1, but far better than one-to-one. The house edge on this bet comes in at almost 14%, a huge edge nevertheless. You only have to be somewhat insane to make this particular bet.
All the carnival games such as Caribbean Stud, Three-Card Poker, Four-Card Poker, and Let It Ride also give the house a much better chance of having longer winning streaks than losing streaks against the player. Let's take Let It Ride as an example. While this game has a loyal following, that following plays a game where the house wins approximately 75% of the decisions and the players win approximately 25 percent of the decisions. The player will have much longer losing streaks; the house will have much longer winning streaks. However, to make up for this inadequacy, many winning hands at Let It Ride pay a premium bonus, bringing the house edge down to around three percent.
Information about the casino-favorable nature of streaks is not some arcane but useless knowledge. Knowing this tells you a very important thing — gambling systems based on the erroneous idea that the house and the player will experience the same types of streaks are wrong. Using them to win money at the games is a sure way to disaster.
