Fallout Shelter has grossed $100 million since launching four years ago, according to data from Sensor Tower Store Intelligence.
In August last year, Sensor Tower estimated the game had reached $90 million lifetime revenue, meaning it generated roughly $10 million over the last ten months.
Arriving on mobile in 2015 to promote the launch of Fallout 4, the game has seen considerable success since, grossing roughly $68,000 a day on average.
Not only does it have a spin-off headed for China, it was announced last week at E3 that the game would be ported to Tesla cars.
While Fallout Shelter has been a global hit, it's primary market is the US, which accounts for roughly 60% of revenue.
The UK is the game's second largest market, accounting for 9% of spending, followed by Germany (5%), Canada (4%), and Australia (3.4%).
China is the largest Asian market, and ranked No. 6 in global revenue having grossed $3 million.
Sensor Tower estimates that Fallout Shelter has over 63 million downloads across the App Store and Google Play.
