Super Mario Runhas officially achieved over 40 million downloads in its first four days of release.
Nintendo has also revealed that the game was the most downloaded title in 140 countries and entered the top 10 of 100 country's grossing charts.
Super Mario Run is free-to-start with a $9.99 in-app purchase to unlcok the full game, so the download figures do not equate directly to sales. Nintendo did not reveal how many players converted to paid players.
The figure beats Pokemon GO, which was estimated to have reached 10 million downloads in seven days of release. That said, Super Mario Run was released in 150 countries simultaneously, while Pokemon GO was slowly rolled out around the world.
40 million downloads surpasses SuperData Research's estimate of 30 million but is still 10 million shy of Sensor Tower's 50 million downloads estimate. The rate of downloads does imply that the game should hit this target soon.
There has been a mixed response to Mario's debut on mobile. Investors have reacted poorly to the game's poor App Store user reviews and business model.
PocketGamer.biz has discussed whether the negative reaction to Super Mario Run's pricing is justified or not.
