Me and my team developed a slot machine game, and posted it on Google Play. Right now, it sits in position 460+ of the casino category. The number of installs is less than 1,000 and daily users range between 90 and 140.
I want to increase the number of installs to promote my game in the store, but I need also these installs to be converted to daily users. I tried some big networks that provide a huge amount of installs, but they only convert to uninstalls.
Can anyone suggest a trusted source with good prices and good quality of installs?
