Firstly, you're seeing some survivor bias here. As per this infamous quote - https://twistedsifter.files.wordpress.com/2018/02/febbie-downer-19.jpg https://twistedsifter.files.wordpress.com/2018/02/febbie-dow... - most people don't recommend things randomly. Secondly, there's another quote (that I can't find the source of) "when I share something, it is because I love my friends; not because I love your brand." What does sharing my score of your game do to improve the lives of my friends? Thirdly, you need large anchors. Most things which go viral are because someone "influential" started sharing it. More often than not that's a paid placement. Sometimes it is just asking your friends to share. Very rarely is it organic. Finally, there's no science to this. If there was, large game studios would be consistently churning this stuff out. The only way to be in the right place at the right time is to spend a lot of time in the wrong places.
