Super Mario Run is estimated to have generated $30 million in revenue from 90 million downloads in under a month since it launched.
The figures come from the Wall Street Journal, which cites Newzoo as its source for the estimates. It suggests that three million users converted to paid players, a conversion rate of just over 3%.
Nintendo officially announced that the game had surpassed 50 million downloads on December 23rd. The figures therefore estimate it has achieved another 40 million downloads in the 11 days following.
3% is a fairly average conversion rate for most free-to-play mobile games. However, given that Super Mario Run has only one IAP, this conversion rate only indicates a finite number of sales, instead of continued revenue streams.
The game now has less than two weeks to reach Sensor Tower's estimated $71 million in revenue. At its current conversion rate, the game would need to surpass 200 million downloads to hit that estimate.
Pre-registration for Super Mario Run has started on Android devices, which implies the game should be available on the platform soon. How the launch will impact sales is yet to be seen.
