What if in-app purchase came to real life?
On street hustling, Free-to-Play mobile games, and the future of impulse purchases on our phones.
Street hustling
Three-card Monte is a classic street hustler’s game. The dealer shows you the target card — say, the ace of spades — then leisurely shuffles it with two other cards and places them in a row, face-down. Your job is to pick the target card. Pick right and you win.
The game starts out shockingly easy. You’re offered the chance to play a few rounds for free — or at a very low cost — just to get the hang of it and you win each hand. Not only does your confidence rise with each turn, but you find yourself amped-up from playing the fast-paced game on a bustling street. With your adrenaline rising, you reach into your pocket, pull out your wallet, and drop $20 on the table to up the ante.
And just like that it’s gone.
The dealer introduced a sleight-of-hand to increase the difficulty of the game — free to play, nearly impossible to win.
The job for the Three-card Monte operator is to build your confidence enough to entice you to reach into your pocket and overcome any second thoughts you might have. Mobile game makers have a word for the obstacles that stand between the player and the designer’s objectives — they call it “friction”.
Let’s try to imagine what would happen if friction were greatly reduced in the real world. If you merely needed to press a button on a piece of glass to put your money down, it might look something like this…
The real world, in-app-purchas-ified
Of course this isn’t just hypothetical — it is emblematic of how a large swath of app developers generate revenue. Known as “freemium” apps, these games and services are free to use at first, then charge for upgrades as the user advances.
While this can often be a good deal for discerning consumers — after all, it amounts to a free trial — it opens the door for potential coercion. Street hustlers, arcades, casinos, video games and even supermarkets, have all utilized the power of the impulse purchase to drive sales.
These industries know customers are more likely to buy when they are:
- In a state of heightened competitiveness
- Cognitively drained (e.g., by a fast-paced challenge)
- A kid who hasn’t personally earned the money they’re spending
- Using an intermediary currency (e.g., poker chips, in-game “coins”)
- Building an attachment to something before they’ve learned the price
- Already invested time, money or effort into something
As this account suggests, a game player can be aware of the pitfall and still succumb to coercion while in the heat of gameplay.
If these dynamics are not familiar to you, I’ve created a few illustrations of what the real world would look like if it had free-to-play in-app purchases sprinkled throughout your day. This should hopefully evoke some of the visceral anxiety experienced by game players when they hit an in-app purchase wall.
In-app purchase required to keep playing beyond 15 minutes
Virtual currency obfuscating real prices
The threat of sunk resources
Offering life-saving measures only when you’re most vulnerable
Failing to disclose arbitrary pricing schemes
Paying your way to defeating your friend
Beyond games
Free-to-play games profit more than any other app genre. A snapshot on August 8th found that 8 out of the top 10 grossing apps in the Apple App Store are free with in-app purchase.
But as apps collect more data about our daily routines, we can expect them to alter our behaviors in unexpected ways. Unlike games of Three-card Monte played on urban street corners, our devices are with us at all times. Consumers will need to be more mindful of how they transact on their devices and we can expect the apps of the future to entice us when we are most vulnerable.
