Super Mario Run has been download 37m times between December 15th and December 17th.
That's according to data firm App Annie, which revealed that the US accounted for 11m of those downloads and that 2m UK gamers own the title.
We have asked App Annie how many of those downloads converted into full purchases of the title. The game was available for free to download, but only included a small proportion of the game. Those that wanted to experience all the levels had to pay $9.99 (Ł8) - which is significantly higher than your normal smartphone title. We'll update the story once we've received a figure.
The game is currently only available on iOS and on average people played the game for 2.5 times each day (over the three day period). The average play time of these sessions was 5 minutes 35 seconds - so just over 13 minutes a day.
App Annie says that people played the game longer on iPad rather than iPhone, although only slightly. iPad owners played for 14 minutes every day, whereas iPhone users played for 12 minutes.
Those average times may sound low, but again, it'll be interesting to see how that figure looks among those that paid for the full product.
App Annie said last week that the game was the top ranked app across 60 countries, had secured 10m downloads in it first day and generated $4m in revenue.
