Hyper Casual games are dominating the App Store Top Charts.
In early in 2017, we saw the rise of Hyper-Casual games going main stream with publishers like Voodoo.io leading the way with their smash hit paper.io. These usually lightweight games, consisting of nothing much more than an addictive core loop on launch, are typically a few steps ahead of a MVP ( minimal viable product ) or prototype.
Pushed heavily via social media campaigns ( Snapchat / Instagram / Facebook ) publishers can achieve extremely low CPI's ( cost per install ) and thus propelling these simple small mobile games to the pinnacle of the mobile App Stores with a relatively modest budget. Because if this, they are highly scalable and massively sharable and often go viral pretty fast.
