(CNN) -- With its glassy touch screen, powerful graphics, crisp sound and tilt feature, the iPhone is more than a smart phone for some users -- it's a portable entertainment system.
t's also become a potential gold mine for entrepreneurs who create games for the device. Just ask Steve Demeter, developer of the popular puzzle game "Trism."
A former ATM software designer for a large bank, Demeter created "Trism" in his spare time and pitched it to Apple last spring. The company made the game available for download with the July launch of its App Store, an online provider of applications for its iPods and iPhones.
Priced at $5, "Trism" earned Demeter $250,000 in profits the first two months.
"It's done phenomenal business," said Demeter, 29, who lives in the California's San Francisco Bay area. "I'm very honored that so many people would enjoy my game. I get e-mails from 50-year-old ladies who say, "I don't play games, but I love Trism.' That's the coolest thing."
It can take dozens of professional developers and millions of dollars to create a video game for a traditional console such as a PlayStation or an Xbox. But the iPhone and the App Store have helped democratize game development by opening the field to any software coder with talent and a clever idea, industry observers say.
