Super Mario Run has now been downloaded more than 78m times, Nintendo announced today in its latest financial briefing.
Of that 78m, around 4m went on to pay its one-time unlock fee - a good but not amazing conversion rate of around five per cent.
The company's mascot jogged onto iPhone and iPad on 15th December last year - and was quickly downloaded 40m times in just four days.
Super Mario Run gives you free, unlimited access to most of its first world. Beyond that, it's a one-off £7.99 (now £9.99 due to Apple's recent App Store price hike) unlock fee - something which surprised many App Store customers more accustomed to free-to-play games.
The app hung around in the Top Grossing chart for a while, although has now sunk without trace.
Bloomberg reporter Yuji Nakamura reported these figures from the mouth of Nintendo president Tatsumi Kimishima. They're actually absent from today's Nintendo financial briefing - Super Mario Run is lumped in with a pre-existing mobile/IP sales category.
Nevertheless, you can see its impact:
Super Mario Run will get another boost, however, when it launches on Android devices in March, alongside the Android timed-exclusive Fire Emblem Heroes. Nintendo's planned Animal Crossing mobile game has been delayed.
