Super Mario Run launched last week with much anticipation, as Nintendo’s first real entrance into the iOS gaming market. Now, Apple and Nintendo have announced that the game has set a new App Store record with more than 40 million downloads in four days.

In a press release issued by Nintendo, the company says that in addition to its top ranking in the “free” chart of the App Store in 140 different global markets (of the 150 where it’s available), it’s also now in the top 10 ranking for best grossing games in 100 different markets.

40 million in four days is a notable achievement, and it came after a substantial marketing campaign. For the first time ever, Apple allowed users to be notified in advance about its release, and the App Store remains plastered in advertisements for it. Nintendo also promoted it on Jimmy Fallon’s mainstream late night TV show on NBC.

Nintendo hasn’t said yet how much the game has generated in revenue. While “Super Mario Run” is free to download, it costs $9.99 to unlock the rest of the game.

The game is only available for iOS devices right now; it’s scheduled to come to Android in 2017
