Ucool spent $2.25M on the worst-rated Super Bowl commercial

The Super Bowl turned out to be a mixed bag for mobile game companies that advertised during the television broadcast.

Ucool said it spent $2.25 million on its 15-second Super Bowl ad for Heroes Charge, a fantasy role-playing game. But it turned out to be the worst-rated of all 61 Super Bowl ads, according to the Ad Meter poll on the USA Today website.
