GungHo Online Entertainment Inc.'s presence on the stock market has been growing rapidly on the growth of its monstrously popular smartphone game "Puzzle and Dragons."

After starting the year at ¥84,200, GungHo's stock price had climbed to ¥1.26 million at Friday's close on the Jasdaq. This brought its market value to ¥1.45 trillion, sending it past rivals Gree Inc. and DeNA Co.

GungHo, which debuted on the Jasdaq in March 2005, even passed Nintendo Co. on Tuesday before the iconic video game maker bounced back Wednesday. It is also close to eclipsing Internet giant Rakuten Inc.
