I was looking on google play and I found this game: Alfie Run Ok, it's a bad game.. but it got 1kk downloads in less than a month.. 10k in 2 days, 50k in 4 days and 100k in 5 days. How did they made this? How many install they have bought? Any ideas? I have an app with the same niche and I have only 1k downloads.
