It's becoming a bit of a trend that mobile games drop a day or so earlier than expected. We saw the same thing happen with Niantic's Harry Potter: Wizards Unite a couple of weeks back. Pushing out mobile titles a little ahead of schedule helps developers and publishers avoid a sudden, massive impact on their servers that might disrupt the player experience. Nevertheless, everyone will surely be glad to start playing Dr. Mario World early.

Update 7/9/18 12:56PM ET: This post has been updated to reflect that Dr. Mario World is now available on Android as well.
