Stuck In The Machine Zone: Your Sweet Tooth For 'Candy Crush'
Originally published on Mon June 9, 2014 10:04 am
If you have a smartphone — or if you've ever used the Internet — you've probably heard of Candy Crush Saga. It's a mobile game in which you line up pieces of colorful candy in rows to score points. The game is simple, but addictive.
According to the game's maker, King Digital Entertainment, Candy Crush has more than 93 million users who play more than 1 billion times a day in total.
Candy Crush has people hooked.
Natasha Dow Schüll, a cultural anthropologist and associate professor at MIT, studies addiction and technology. She says what keeps people playing Candy Crush is something called the "ludic loop."
"It's you and the machine," she tells NPR's Arun Rath. "There's no real character development or narrative arc. Kill the monster; kill the monster again; kill the monster again. You never know when you're going to get the reward [or] how much the reward will be. It's these little ludic loops."
Schüll spent about 15 years studying and spending time with slot machine gamblers in Las Vegas casinos. She says games like Candy Crush can be just as addictive as gambling — if not more so.
"I've heard the expression, 'Candy Crush is like a slot machine on steroids,' " she says.
Perhaps the most addictive element of both Candy Crush and slots is the continuity, says Schüll. In both cases, a continuous stream of small reinforcements (disappearing rows of candy in the former, and cold, hard cash in the latter) can keep players glued to the screen for hours on end.
But mobile games and slot machines aren't just about winning.
"One gambler told me ... 'I get irritated when I win a jackpot,' and I kept hearing that over and over again," she says.
This puzzled Schüll. Why play the game, if not to win?
"I think it's a kind of escape, the retreat from the world, the comfort," she says. "So people actually describe [slot machines] as being reassuring and predictable, which is really counter-intuitive. But it makes sense if you sit and watch people play."
There's a term for the comfortable state of mind brought about by playing the slots. Gamblers call it the "machine zone." Schüll says it isn't confined to casinos — the machine zone is just about everywhere.
"I think that it can be applied more broadly than just [to] slot machines," she says. "It can be applied to compulsive email checking, or eBay auctions, or playlists, where you're constantly using this media to modulate your mood, and you just have it available right there at your fingertips."
ARUN RATH, HOST:
The app "Candy Crush" has over 93 million users playing over 1 billion times per day. If you missed the bandwagon, you can get up to speed in seconds. All you do is touch a candy and swipe it with your finger.
(SOUNDBITE OF GAME, "CANDY CRUSH")
UNIDENTIFIED MAN: Sweet.
RATH: Match three identical candies to crush them and get to the next level.
(SOUNDBITE OF GAME, "CANDY CRUSH")
UNIDENTIFIED MAN: Sugar crush.
RATH: But before you start swiping, I need to warn you - it is very habit-forming. Natasha Dow Schull is an associate professor at MIT. She says the thing that keeps users play so much as what she calls the ludic loop.
NATASHA DOW SCHULL: Ludic would be pure process. It's you and the machine. There is no real character development or narrative arc. Kill the monster, kill monster again, kill the monster again. You never know when you're going to get the reward, how much the reward will be. It's these little ludic loops.
RATH: Schull spent more than a decade making trips to Las Vegas casinos all in the name of science. She says that ludic games, like "Candy Crush," rely on the same psychological hooks as slot machines.
SCHULL: I think I've heard the expression, "Candy Crush" is like a slot machine on steroids. They're quite similar. Its solitary, so it's just you and you're interacting with the screen. You're not waiting for other people. It's just pure repetition, pure procedure. And then there's the element of speed. You are just playing in rapid succession. I know with slot machines, you can play 1,200 hands an hour. I'm not sure how many games of "Candy Crush" you can play. But my understanding is that it's even more of a just continuous process where you don't even really distinguish between one spin or game and the next. You're just going, going, going. And that, that really is the last characteristic. The continuity - continuous, steady stream of small, little reinforcements.
RATH: Speaking of reinforcements and rewards, you know, when you're talking about slot machines, it's sort of easy to understand that reinforcement 'cause, at least occasionally, you'll get a payout. You'll get money back. With these video games, though, you don't get anything like that.
SCHULL: Actually, with these newer digital games, it's really not about winning. One gambler told me - and this really drove the point home - I get irritated when I win a jackpot. And I kept hearing that over and over again. And that sort of flipped the whole thing on its head for me. And they said, you know, I'm there to just keep going. And when I win a jackpot, I have to - everything freezes up. People look over at me. Suddenly I'm back in the world, and sometimes I have to wait for the change person to come and pay me off. To me, that just speaks worlds about this trend toward playing for something else. And, you know, what is that something else? What is that something else that's shared with "Candy Crush" and slot machines? I think it's a kind of escape - the retreat from the world, the comfort. So people actually describe these machines of chance as being reassuring and predictable, which is really counterintuitive, but it makes sense if you sit and watch people play. They're modulating their moods just as people are with "Candy Crush."
RATH: Is that the machine zone?
SCHULL: The gamblers actually call it the machine zone. And I took that term from them because I think that term really nicely captures what's going on. And I think that it can be applied more broadly than just slot machines. It can be applied to compulsive e-mail checking or Ebay auctions or playlists where you're constantly using this media to modulate your mood. And you just have it available right there at your fingertips.
