Certain video poker machines have a 'double down' or double-or-nothing wager feature when you win a hand. I usually avoid this wager, not wanting to risk winnings in excess of my original bet. But I AM tempted to try this wager on winning hands that only pay even money on the original bet. My reasoning is that the machine's usual payback is somewhere in the 96-99% range, which includes rare hands over the long haul; but in this circumstance, this bet would seem to payback an even 100% over a shorter period of time.

The double or nothing feature in video poker is the only other casino bet, besides the odds in craps, with no house edge. Whether or not you take it depends on your reason for playing. If you are playing a negative-expectation game, for purposes of entertainment, then I think you should accept the double-up option in moderation, depending on on your desire or aversion to volatility. The reason is that it is better to play a game with zero house edge than a positive one. However, you have to balance that against your tolerance for risk. If you are fortunate to be playing a positive-expectation game, then I would decline the opportunity to double.

What are the guidelines for doubling up on winning hands in video poker? If I do double up and the 5 cards show a winning hand, would that have been my next hand had I not doubled up?

The double up feature is truly fair and has no house edge. This is one of the few times I say you can go either way and just do what you want. From what I know of how slots are programmed the cards you get in the double up screen are not what you would have got on the next hand. Random numbers are constantly being drawn and those chosen at the exact moment you hit 'deal' determine what cards you get.

On Monday, July 6, 2009, two engineers from Nevada’s Gaming Control Board showed up at the Silverton Casino Lodge. The off-the-strip South Las Vegas casino is best known for its mermaid aquarium.

You wrote, 'The double up feature is truly fair and has no house edge. This is one of the few times I say you can go either way and just do what you want.' The same, of course, is true of true odds bets at craps. So, why promote taking odds at craps and not promote doubling up? Just as you can drop the house edge to essentially nothing at craps, you can do the same thing at video poker or blackjack...My own reasoning is that cutting cards against the casino for fair stakes is just boring, but I'd be interested in your opinion.

You are of course quoting me from my March 24 column. This is a good and fair question. I should point out that taking or laying the odds in craps does not help the player to win more, only to bet more at no additional expense. The reason I encourage craps players to bet on the odds is that it is the cheapest bet on the table and is truly a craps bet. All odds, as well as place, buy, and lay bets win if one number is thrown before another. This is a very fundamental aspect of the game. It only makes sense for the player to make the bet with the lowest house edge. Refusing the odds in craps to bet on something else instead is like refusing a free coffee refill in a restaurant and instead buying another cup.

As I pointed out in the last column some video poker games allow the player to make a double or nothing bet with no house edge. The reason I am not as forceful about taking this bet is that it does not follow the flow of video poker. The video poker player is generally not there to make a mindless even money bet. Gambling should be thought of as entertainment, for which the player should expect to pay for. If the player doesn't get any entertainment value out of the double up feature then he shouldn't pay for it, even with no house edge. So my advice to the video poker player is make the double up bet if you enjoy it, otherwise don't.

How does multiple doubling up in video poker cut the house edge?

This question refers to advice I gave in my newsletter, suggesting video poker players take the double up option when playing for a bonus at a Playtech casino. Doubling up does not lower the house edge of video poker, but does introduce another bet with zero house edge. For the same reason you should take or lay odds in craps it cuts the overall house edge playing video poker if you take the double up feature. Playtech does count double up bets towards the play requirement, so it gets the player to the bonus with less expected loss. So unless you are playing a machine with a return of over 100% and you don’t mind extra volatility then I recommend accepting the double up option.

In your last column you said you liked the double up feature in video poker. How many times is the player allowed to double up and how many times do you recommend?

I understand that at least with some machines the number of doubles is configurable but is usually set to 4 or 5. How many times you should take the double up depends on how good or bad the pay table is and your tolerance for risk. If your goal is to achieve the highest expected return then you should double up the maximum number of times, or at least until a win would put your over the W2G threshold of $1200. When I play negative pay tables online I usually double up to $100 to $1000, depending on how much action I have to grind through and my winning goal. My advice is to ask yourself how much you are comfortable betting on the turn of a card and keep doubling up to that point.

If there is no house advantage in the double up feature in video poker, why do the casinos offer it?
Double

Just to attract customers who like it. It definitely lowers hands per hour, and thus profits, but if they get extra players it may be worth it.

I am a very big fan of using the double up feature of video poker. Is there any limit to the amount of money you can win with double up or is it pure luck. For instance does a game only pay out for instance 99% of all credits doubled, or can you win any amount not matter how much credits has been lost at double up. It is crucial for me to know this.

Any legitimate game maker has the double up feature as a truly fair bet with a 100% return. So you have a 50/50 chance of winning any given bet (not counting ties) regardless of the amount bet or the results of past bets.

In slots or video poker, when playing with a double or nothing feature, how many times should I try to double?

It depends on your reason for playing. If you are trying to achieve some winning goal, like doubling your bankroll, then you should keep doubling until you reach your goal, or you reach the maximum number of doubles allowed. If you are trying to play as long as possible on a given bankroll, then I would double only on small wins, and then only once. If you have some combination of both goals, then I would have a mixed strategy. The more important winning is to you, the more aggressive you should be doubling. The more important “time on device” is to you, the less you should be.

Every gaming machine addict or enthusiast dreams of hitting a jackpot, the bigger the better! The flashing lights signalling that huge payout is a massive draw in casinos the world over, and the reason why slot machines take up so much space. Now imagine if your dream became a reality and you could repeat it again and again and again?

That’s exactly what happened to John Kane who discovered a bug in his favorite video poker slot and took it for millions!

In the beginning

The amazing story begins back in April 2009 when Kane – a virtuoso pianist with a penchant for Game King video poker – stumbled upon a very serious hole in the machine’s programming. There was a bug which had gone undetected for seven years, according to the Wired.com piece on this remarkable tale!

By Nevada standards, The Fremont Hotel and Casino in downtown Las Vegas’ Glitter Gulch is an unassuming place, offering topless dancers and cheap drinks, but it did have exactly what John Kane looked for in a casino – four Game King machines in a row! And for some strange reason, on this day it decided to reward him with a $1000 jackpot.

The only catch being, Kane hadn’t actually won, there had been a glitch. Kane knew the machine inside-out, having installed one in his Nevada home years previously, so he reported the glitch which had rewarded him to the supervisor, but the supervisor just laughed, thinking Kane was joking!

Machines don’t pay out unless you hit the correct sequence. Kane’s video poker hand wasn’t a winner , he had merely hit the Cash Out button to take his more modest winnings to a new machine, but the jackpot candle at the top of the Game King lit up anyway. The $1000 was his to keep, and now Kane knew that there was a serious flaw hidden somewhere inside the machine’s code.

Old school techniques

Now, unlike playing on an online poker site or online casino site like casino.com, these money-making machines are not controlled via the internet, so every piece of code resides in circuit boards which are manually produced, inserted, and checked. Kane wasn’t a programming expert, so he turned to the age-old method of trial and error. If he could discover the flaw, he could win at will!

This turning point in Kane’s life was to lead to some very serious money – and some very serious consequences. He enlisted the help of Andre Nestor, a friend from the good old days when the gaming addicts would play the machines together, desperate for that elusive, life-changing big win.

Nestor was a superstitious guy, a younger man who was haunted by the gambler’s nightmare of not playing the numbers his dreams had told him to, thus missing out on a Pennsylvania lottery jackpot some 15 years earlier.

Hitting the big time

Between them, they worked out the first part of the Game King machine’s bug – you could lose at the lowest levels ( 1 cent) for a long time, but when you finally hit a huge hand, you could suddenly switch to 50 cent play, and the machine would pay out on the much bigger sum!

Jackpot! Lose small, win big!

You had complete control,” said Nestor. 'You could win $500,000 in one day.'

It wasn’t easy to replicate this bug-control plan, but the two men soon developed a winning sequence, and the money started to roll in.

The Double-up and the Missing Link

Video Poker Double Up Flaws

As with most slots, you can gamble your winnings and take a chance of double-or-nothing and similar options. Now, if you had just cracked a machines fatal flaw and were winning big, would you be satisfied with that or want to double your money?

For Kane and Nestor it was a no-brainer. The DoubleUp feature was free money, and the pair netted more than $100,000 from the Fremont casino alone, but naturally there were eyes on the pair by now!

Casinos track wins and losses in all parts of their domain – after all, they have to make a living too! Spotting that the winning pair of gamblers always used the DoubleUp feature, the casino simply disabled that option, and the Kane Nestor combo started to hit a loss.

Now they knew the DoubleUp option was needed to win anything – nothing happened when it was switched off. And even better for the bad boys, their trial-and-error approach had shown that they could actually replay the same winning hand over-and-over-and-over again!

No honour among thieves

Of course, greed is a terrible thing when it comes to gamblers and money – too much is never enough! Kane and Nestor were soon arguing over the financial split from their ill-gotten gains.

Kane wanted more than half as it was his initial plan and ‘work’ which had brought them their riches. Nestor claimed that he had solved the DoubleUp segment of the puzzle, and therefore they were level. What to do?

Split and hit

Relationships end, and often have serious consequences, and so it was here with Kane and Nestor.

Kane kept his ‘show’ in Vegas, pulling in a haul from the GameKings of more than $500,000 according to the FBI records. His four 9’s on one of the bug-ridden slots in Vegas’ Wynn Casino was paying out for days at a time, eventually netting him $225,240. Nestor, on the other hand, returned to his native Pennsylvania where his own winning streak seemed to have no end.

All good things…

Sometimes the authorities may be slow, but they are generally not stupid! The early summer of easy money was coming to an end for the duo, with Kane’s latest winning streak being watch by the eagle-eyes of the Silverton Casino's director of surveillance, Charles Williams.

After cashing out his latest scoop, Kane was met by casino security as he tried to leave. The game was finally up! As yet, nobody knew how he was doing it, but that didn’t matter – he had to be stopped and the Silverton’s security team did just that, hand-cuffing him to a chair in a back-room.

His $27,000 in cash confiscated, he was soon staring at the face of an armed Gaming Control Board agent and being charged with suspicion of theft. But his friend Nestor was still a free man, living it up in the casinos of Pennsylvania.

…come to an end

Ignoring warnings from his onetime friend and accomplice, John Kane, Nestor continued his wicked ways, also taking close to $500K with his knowledge of the Game King weaknesses. It went on until one fatal day when the casino refused to pay out on his winnings. The Meadows Casino and Racetrack in North Strabane had seen enough – Nestor was now a marked man.

When the State police finally raided his home, it resulted in the biggest gambling scandal the state had seen since legalizing slot machines five years previously. Nestor was charged with a staggering 698 felony counts, had all his winnings taken and was given 10 days in jail to think about what was about to happen.

It’s a federal bust now

What was about to happen took another year, but would scare Nestor and Kane to the core. Their state trials, at jury selection stage, were disrupted by federal officials – they were now under the jurisdiction of the Justice Department. It had been decided that their cases were inter-state crimes, with all the extra possibilities of jail-time that decision brought with it.

What did we do wrong?

As a defence argument, 'What did we do wrong' it was very clever and very simple:

We didn’t tamper with the machines, we simply exploited a flaw in the designer’s programming’. As Nestor proclaimed to the media on his federal bust: “They put a machine on the floor, and if it has programming that doesn't take your money and you win on their machine, they will throw you in jail!”

With conspiracy and violations of the Computer Fraud and Abuse Act on the prosecutors table, the assistant US attorney for the District of Nevada Michael Chu stated in court papers that:

To allow customers to access previously played hands of cards at will, would remove the element of chance and obviate the whole purpose of gambling,” adding, “It would certainly be contrary to the rules of poker.”

Slowrolling

For 18 months the show rolled on, the arguments on both sides seemingly having equal merit.

The defense claimed that there couldn’t be computer hacking charges levied against the pair: they hadn’t hacked anything, and if the Game King slots allowed Kane and Nestor to do something, then that something was “authorized access” by definition. “All these guys did is simply push a sequence of buttons that they were legally entitled to push,” claimed Leavitt, Kane's attorney.

In the meantime, other non-gambling hacking cases had been made public, the judge in the Game King case drawing parallels and ordering the prosecutors to justify such charges. They couldn’t and didn’t – and the most dangerous of the charges to the duo were dropped.

The Prisoner’s Dilemma

This classic case of ‘game theory’ was likely well-known to both Kane and Nestor, or at least they managed to replicate the best result for both men!

Basically, the prosecutors offered each of them a deal. The first man to agree to testify against the other would get away with five years of probation and no jail time. The other, obviously, would be hit with the full force of the law.

The traditional view is that the prisoner’s dilemma would see one or both of them offer to testify, even though keeping silent is the optimum for them taken as a pair. To their credit, Kane and Nestor either respected and liked each other too much, realized that the criminal code of keeping schtum was paramount, or, most likely, their lawyers had realized what the prosecution ploy was because they had such a poor case!

Freedom comes at a cost

Video Poker Double Up Flaw Against

Whatever the reason, the Game King kings both declined the offer and…within a few months they were both free men! The government had finally accepted that they couldn’t really argue their case well enough to secure a conviction – the men really had simply exploited a basic flaw in programming.

And so both men were back on the streets, although quite how much of their winnings they were left with is very unclear. Nestor claimed that he had nothing left and was facing a huge IRS bill on his winnings, some $240,000 being sought, while Kane has kept silent about the whole affair since.

The machine codes, naturally, were analysed, changed and tightened up – although the $1million+ which Kane and Nestor managed to siphon off has doubtless been recouped – and more – by the popular video slot.

For the gambler who has found a bug, perhaps the moral of the story is not ‘don’t exploit it’, but rather ‘don’t be greedy and don’t get caught!’
