Hypercasual games downloads fell last year due to the ongoing pandemic, according to Sensor Tower.
The mobile genre was rapidly rising, having grown exponentially in recent years, with that growth set to continue into 2020.
However, the COVID-19 outbreak swept the globe, causing many countries to enter mandatory lockdowns. As a result, many were stuck at home.
"The pandemic halted the rapid Hypercasual adoption boom seen over the past several years," said Sensor Tower.
"With significant reductions in commuting and travel in response to COVID-19, demand for these simple games fell, and Hypercasual genre downloads decreased year-over-year each quarter between Q2 and Q4 2020.
