If you've been staring wistfully at the many iOS folks who are playing Super Mario Run on your commute, wondering when your Android gizmo could get in on the action, maybe stop doing that. First up, it's a little creepy and, secondly, soon enough you'll be able to play on your own device. To find out exactly when, you can pre-register for the app via Google Play and be alerted as soon as the download is ready. Precisely when that is isn't clear, but hopefully the gap will be shorter than it was between announcement and availability on Apple's mobile OS -- a month.
