A good/experienced game programmer will cost you minimum $3000-3500 monthly. Assuming you want to make a decent game with quality graphics, account cost of graphics and sound to $5k-$10k ( it can be outsourced for a one time cost).
Assuming that at least 6 months of programming is needed to code a quality game with 10-20 levels, you can do the math now.
Programming cost = 21,000$
Graphics cost = 10,000$
Addl Misc Costs(project mgmt tools, development software, game libraries)= 10,000$
Software Testing(get the game tested via a crowd sourced service like usertesting.com, before you do a public launch, this saves a lot of headache and bad feedback on app stores as per my personal experience. First impression is the last impression for many users.) = $5000-10,000
Cost Over-run(normally happens in all development projects, including gaming projects ) = $5000
This would get you something like angry birds, candy crush or similar popular games in any/all platforms.
