TOKYO (AP) — Japanese video-game maker Nintendo says its net profit jumped 31 percent to 135.2 billion yen ($1.2 billion) in April-December, helped by the popularity of its Switch hybrid game machine.

Kyoto-based Nintendo, which makes Super Mario and Pokemon games, said its sales in the first nine months of 2017 more than doubled from a year earlier to 857 billion yen ($7.9 billion).

Profit in October-December was 83.7 billion yen ($771 million), up 29 percent year-on-year.

Nintendo, which also makes the 3DS portable console, has scored success in offering games for smartphones and other devices that aren't Nintendo machines — a move the company had resisted for years, but an area that is yielding strong results.

The company revised its full-year profit upward by 41 percent to 120 billion yen ($1.1 billion).
