The figures (at least, the way you've posted them here) are misleading.
The $11,500 is gross income. The portals that sell it are going to take a hefty cut before the developer gets anything.
That aside, the figures on gameproducer.net don't add up anyway. They claim sales of 334 units at $12.95 per unit, which is $4,325.30 gross income. I can't work out how they get $4,649.84. Likewise with the other two versions.
