Slot:
A narrow notch, groove, or opening, as in a keyway in a piece of machinery or a slit for coins in a vending machine.
If a winning combination of symbols lines up on a payline, the player receives credits based on the amount he or she has wagered. A spin can consist of any number of reels and may feature multiple symbols, including scatters that trigger bonus rounds. Free slot games also typically offer a variety of ways to win, including a Wheel of Fortune or a multiplier that can increase the size of any winning line. While free slot games are played for play credits rather than real money, they are still addictive and can cause financial ruin for some people. As part of her MIT doctoral dissertation, cultural anthropologist Amy Schull spent 15 years in Las Vegas, tracking the evolution of slot machines and their reliance on psychological insights to keep players gambling. Her research shows that slot machines have become the driving force behind casino profits, and casinos employ a dizzying array of strategies to encourage gamblers to spend more time playing. Regulatory agencies are trying to slow down the growth of video gambling, but Schull argues that it’s difficult to throttle a machine that has evolved to be so addictive. Some proposed interventions, like pop-up messages warning players that they’re playing too long, have backfired. In the end, Schull says, most gamblers don’t go to casinos to win a jackpot but for the gradual drip feed of winnings and losses that keep them in the game.
