"We buy our smartphones and tablets, and we have a whole plethora of options that are free to play," David Gibson, senior analyst at Macquarie Research Japan, told CNBC. "That sort of thing is not available on the Nintendo platform."
According to Nikkei, Nintendo's new mobile offering are likely to be free minigames, or demos intended to draw players to its consoles.

That strategy could work, said CNET Editor-in-Chief Lindsey Turrentine.
"I think they will draw in console players—if the mobile games are exceedingly good and leave the players wanting more," Turrentine said.
"It's a safe assumption that most of these games will be targeted at children, [who] will get excited about a brand and all its permutations if they find the characters and potential exciting enough. The challenge will be making those brands compelling enough to chose Nintendo's console tech over others," she added.

"At this point, Nintendo needs to make a really hard decision. ... It might need to go the way that Sega went, which is to just create games for other platforms," Turrentine said.
Gibson at Macquarie said Nintendo could also open its platform for developers to make more games available on its consoles.
