Nintendo Co. found out with its first smartphone game it's tough to get people to pay $10 even if the draw is Super Mario. With its second mobile title, the Japanese powerhouse is taking a different approach that is potentially more lucrative — and much more controversial.

The technique is called gacha in Japanese and it has all the controversy the English reading of the word implies. It's extraordinarily profitable in Japan — but even here it has raised concerns from regulators who say it can be addictive and manipulates people's gambling spirit.
The game rose to No. 4 in Japan's iOS revenue rankings after its release, according to researcher Sensor Tower. Partner DeNA Co. soared as much as 7.9 percent.
