When people think of casinos, they often think of games like blackjack or roulette — high-stakes bouts of chance where fortunes can be won or lost in seconds. But that image is increasingly obsolete.
"Slot machines have this reputation for being these arcade devices only played by little old ladies," Schüll says. "But these devices are now driving the gambling industry and bringing in the majority of profits." By the late 1990s, slots were twice as profitable as all the other table games combined. She quotes one gambling official estimating that the machines account for as much as 85 percent of industry profits.
How did slots become so widespread? During the recession in the early 1990s, state legislatures started looking to increase revenue without raising taxes — and many of them settled on bills to allow machine gaming. "It was much easier to push through legislation [expanding the availability of slot machines] than things that carried a weightier vice image, like table gambling or poker," Schüll says. (...)
The gambling industry has realized that the biggest profits come from getting people to sit at slot machines and play for hours and hours on end. (Schüll says the industry refers to this as the "Costco model" of gambling.) As such, slot machines are designed to maximize "time on device."
Computerized slots have made this all possible. Again, in the old days, you pulled the lever and either won or you lost — and when people lost, they'd walk away.
Today's multi-line slot machines are far more elaborate. Instead of a single line, a player can bet on up to 200 lines at a time on the video screen — up, down, sideways, diagonal — each with a chance of winning. So a person might bet 70 cents and win on 35 of the lines, getting 35 cents back. That feels like a partial win — and captivates your attention.
"The laboratory research on this shows that people experience this in their brains in an identical way as a win," Schüll says. (And the economics research shows that these multi-line machines are far better at separating players from their money.)
That subtle advance, Schüll says, has helped revolutionize the gambling industry. Fewer and fewer people are now going to casinos to experience the thrilling chance at a big jackpot.
Instead, for many of the people Schüll interviewed, these slot machines have become a "gradual drip feed." They play because they enjoy being in the zone and losing themselves in the machine. Some players she talked to confessed that they actually get annoyed when they won a jackpot — because it disrupted the flow of playing.
