Nintendo is a well-known company for it's playing consoles. To have a Nintendo console it's like a badge that you are a true gamer.
Nowadays, the company is seeking new ways to market their products. It seems that they will develop a Nintendo app with free games for customers on Android and iOS. This will be a good move for Nintendo, because they want to use a new way of marketing.
So, Android and iOS users will find free demo games on the Nintendo app. The idea is that customers feel what is like to play Nintendo's games and so they will buy a console. Apparently these mini-games will be completely free and Nintendo isn't planning on using a freemium model either. Rather, the exposure and anticipated boost in game and console sales will offset any development and promotion costs.
This is not the first time when there are rumors that Nintendo will enter smartphones and tablets market. Nintendo's officials say that they don't want to develop new products on the smartphones market, they just want to use this feature as an marketing tool, to grow their consoles sales.
