Taking What the Casinos Give You
$6,000 Welcome Bonus
Casinos are in the business of making money. In theory, casinos offer games of chance where the odds are in their favor and invite players in to play games that are rigged against them.
Under this theory, there would be no such thing as an advantage gambler. But the theory is greatly simplified — primarily in two areas.
First, some of the games offered are games of skill. You’ve heard of poker, blackjack, and sports betting. There are many more. And skillful players will do better than players without the requisite skill.
Second, casinos make mistakes — of many different types. Many times these mistakes lead to opportunities for players. Today I want to look at types of exploitable mistakes that I’ve discovered over the past 30 years. Many times, I’ve taken advantage of them. Sometimes I passed intentionally. Sometimes I heard about it afterwards. Sometimes I heard about it in plenty of time but didn’t recognize it as the profit-making opportunity it was.
This list is nowhere near exhaustive. Most of these happened in Las Vegas, but I’m sure they happened elsewhere as well.
- Game manufacturer providing incorrect information. The example that comes to mind here is Pick’Em Poker. This was a game that was worth 99.95%, but Bally Systems, the creator of the game, published that it was worth 98.8%. The game was popular (99.95% games tend to be that) and casinos kept putting it in for years — thinking they still had a cushion. Eventually, Bally sold the game to IGT, who rebranded it as Pick A Pair. IGT did include the original pay schedule in their offerings, but few casinos wanted a 99.95% game on their floor.
- Individual machine mismarked. Texas Casino (before it was Texas Station) had one 10/7 Double Bonus (100.17%) machine what was marked 9/7 (99.11%). While the front of the machine said it would pay 45 credits for a full house, you actually got 50 credits.
- Machine “too loose” for the casino floor. In 1995 at the Colorado Belle in Laughlin, the loosest games were dollar 9/6 Jacks or Better (99.54%), with most of the games quite a bit tighter than that. Two Bally Gamemaker machines were added. These machines included a number of games — including the Bally version of 10/7 Double Bonus which paid 400 coins for a straight flush rather than 250 and was worth 100.55%. The game lasted for a few months before the casino downgraded it.
- There are a number of examples where employees were bribed for small benefits. Slot floor people are minimum wage employees. If they’re in charge of handing out something worth $5 to players, which I’ll call scratchers because that’s a common way to do this, players will offer to tip $1 to get another scratcher or two. The casinos keep track of cash, but the scratchers are unmonitored, and employees are instructed when to hand them out. Under these circumstances, fraud and collusion will occur. Far better to design a promotion where this can’t happen.
It’s been more than 25 years since I bribed a casino employee to give me extra scratchers or such. But at the time, I was very tight on money and “needed” the extra. Today I’m not tight on money, but millions of players are. When casinos make it easy for players and employees to cheat, they will.
- There are examples where prizes, which are supposed to be chosen randomly, have codes on them which the savvy players can figure out.
One casino mailed out some “to be scratched off in front of a casino employee” cards, with daily prizes ranging from being worthless to 5x points (which could be worth thousands of dollars to the right player.) If you had a strong light, you could see the prize through the card. It could be a hassle to go back to the same casino every day — but if you know beforehand when it’s really worth it, you make trips at the correct time. In the case of midnight-to-midnight 5x points, you arrange your whole schedule around being there at midnight when it starts.
Another casino let you pull scratchers out of a bowl. You then scratched off at the booth to reveal your prize. On the back of the cards, however, was a number which told the savvy player what was on the card. A code ending in 55 might signify $5 in free play and a code of 82 might signify $100 in free play. Some booth employees realized what was going on, and held the bowl at the player’s eye level, telling the player to draw one without looking at it. Some players, of course, drew more than one, scanned them all, and apologized as they kept the best one.
- Point multipliers are the bread and butter of many video poker professionals. To know how good this is, you must know how much single points are worth and what the game itself is worth.
Sometimes you see mistakes with multipliers. Like when the marketing director at Eastside Cannery decided 10x points was a good idea because that’s what a competitor offered. The competitor offered base points of 0.05% and Eastside Cannery offered base points of 0.1675% and looser games. There were people holding machines for more than twelve hours before the promotion started.
Just knowing that one casino offers 4x points on Tuesday while another one offers 2x points on the same day doesn’t tell you which is the better play. It depends both on the value of the game you’ll be playing and how much single points are worth.
- Theoretical on machines. Years ago, several Harrah’s properties in Las Vegas offered high denomination 9/5 Jacks or Better (98.45%) with a theoretical of more than 4%. Some players came in twice a month, playing $150,000 coin-in at an expected loss of $2,300 each time) and they received $3,500 in free play each time they did this. Plus, slot club benefits.
I didn’t hear about this one until near its end, but I did play it for a while. Long enough to be “discovered” by one of my students who was aghast that I was playing 9/5 JoB rather than the nearby 9/6 JoB machines (which required 2½ as much coin-in for one Tier Credit and had a theoretical of 0.46%). This lady asked me several questions and I just smiled and said nothing. I’m sure she suspected I was a fraud whose actions were not the same as his words.
Video poker is a lot more complicated than just learning which games to play and how to play them.
