you might reach millions in a few seconds. and if only a portion of them install the app they might start earning enough again to get out of that marketing cost.
you are right that candy crush games exists long time ago but it was not made like candy crush..
the graphics are really great... after your app got popular and you have lot of downloads (also without any advertisement) then its pretty easy for you to invest in advertising, so i don't think they invest from the beginning, i think after a while they did good money from the first "boom" and then they could effort it
whatsapp got more the billion downloads and they have not put 1$ for advertising... i guess also indi devs can make big money if they got a winner they can advertise also there other not popular apps on the big winner apps and got also downloads from there...
every new app from they is a big winner because they advertise it on there big apps, if you have their games you will always see advertising from new games, they even have not to spend money on advertising they use there own apps, its like a snowball...
you just need that only 1 million downloads app, after that "with smart advertising" you can leave pretty good from it...
i tried it and result was very very poor, i spent about 100$ and got maybe 25 installs...
you pay for every click but lot of guys click and dont install your app so google adsense is weak
