Vegas gunman's gambling draws new attention to video poker

Authorities trying to piece together the final days before Stephen Paddock unleashed his arsenal of powerful firearms on country music fans at a Las Vegas concert have at least one potential trove of information: his gambling habits.

Nevada gambling regulators say they're sorting through documents for clues about him and his girlfriend, Marilou Danley. Those can include suspicious transaction or currency reports, as well as information from a player's rewards card, which the casinos use to track their gambling andoffer perks.

Paddock's brother has described the gunman as a high-stakes video poker player who routinely was "comped"casino hotelrooms, meals and drinks meaning they were given to him free.

"He was a substantial gambler. It was a job to him," Eric Paddock said.

A person who has seen Mandalay Bay hotel records that have been turned over to investigators said Wednesday they show Paddock was given a freeroom on the 32nd floor because he was a good customer who wagered tens of thousands of dollars each time he visited. The individual was not authorized to speak publicly and disclosed the information to The Associated Press on condition of anonymity.

The massacre has brought new attention to the world of high-limit video poker and casino compsforhigh-rollers so they can keep them gambling.

Paddock's brother said his brothergambled enough that he was givenfree rooms, poolside cabanas and high-end sushi meals exceeding $1,000.

"He won cars and $250,000 chequesand all this stuff from the hotel," Eric Paddock said.

High-dollar video poker

Video poker machines are a mainstay at casinos around Nevada. Most machines are placed in bars where gamblers can play poker from their stools for 25 cents a hand. They look similar to slot machines.

Stephen Paddock favoured the high-dollar variety version of the game, whose machines are separate from the main video poker and slot areas. These players use strategies that can minimize the house winnings and in some cases gain a minuscule mathematical advantage.

Michael Shackleford, who runs a gambling strategy website called The Wizard of Odds, said based on what is known of Paddock's life, the gunman seems to have been what the casinos refer to as a "premium mass" player one who bets in higher amounts, with a better understanding of the game than the typical player.

Premium mass players pay close attention to the odds in the game they're playing and the payout, and they typically need access to a lot of money because they may have long dry spells where they lose exorbitant amounts.

Eventually, Shackleford said, if players stay true to a perfect strategy one designed to maximize their performance over the long haul, such as by getting rid of potentially decent cards like low pairs to increase chances of a big-payout royal flush their luck will turn, based on statistics, and they'll break even or come close to it. When you add in the freebies from the casino, the player can come out ahead.

"Vegas is full of people that are basically just gambling for free," Shackleford said. "I think the shooter was one of these people who was basically milking the system, getting free vacations."

Why do the casinos have games where the players can come out ahead?

"It's because there are so many bad players," Shackleford said. "For every skilled player, there are probably 100 lousy players. They subsidize the skilled players."

The stress of having so much on the line isn't for everyone, he said.

"In any form of gambling, you need a strong stomach and you need to have a very cool head about the ups and down," he said. "If this guy was a millionaire, it's quite possible he was not bothered by the ups and down. He probably had steel nerves and was a difficult person to move emotionally."

Earning reward points

It's unknown how much Paddock was wagering, but he apparently had been spending more than $10,000 a day in some cases.

A.G. Burnett, the head of Nevada's Gaming Control Board, said investigators are looking for enforcement actions, for any disputes Paddock may have had as a casino patron and at any federally required currency reports of transactions he made greater than $10,000.

Authorities have said Paddock used Danley's loyalty rewards card with MGM Resorts International. The tiered program allows players to accumulate credits and get perks such as bonuses on points earned playing slots, priority hotel check-in and for those who belong to the highest and by-invitation-only level limousine service to and from the airport.

The casinos "know whether he lost money because he never would have gambled for a second without putting the card in," Eric Paddock said.
