How to find a good mobile game company for outsourcing?

There are very many of them, for what certain purposes do you need the one? With more details to your question, I can give you better recommendations :)
Anyway in case of choosing any software development company for outsourcing you should:
- find a not too cheap one, they usually make rather low-quality work and you'll pay even more in the end, while making a choice compare the companies by hourly rates, not prices
- find the company with convinient location, languages for communication and timezone for the both sides
- concentrate on a few of them and check carefully information about them because making the same in case of many companies will take too much time
- check reviews from other clients about the certain company, its work samples and previous finished projects
- choose the company with the same size as yours for improving general quality of your work and partnership, also the one which is really good in several/one programming languages for mobile game development outsourcing , not many of them because that's often a sign that the certain firm isn't really good for working with all of them
- check its plans for future, don't be shy to ask about their company vision, perspectives and how they see their company in a few years, detailed responses in this case indicate that you found a really reliable business partner

I have read that Belarus is among the most demanded countries from the point of view of reasonably priced IT labor power. Belarusian specialists work with large-scale commercial solutions financed by entrepreneurs from the USA and EU countries increasingly frequently. This, in turn, explicitly indicates how many ‘beautiful minds’ with no less ‘beautiful’ ideas there are in this country. You can read more here

I also had a thought about developing an application. I created my application which is successful now, I learned how to develop and maintain my application. But the development was helped by the company from which I ordered my application for the first time. It was the most useful experience for me in my life and I can recommend their company, responsible work and the fastest application they create.
