If you’ve been dreaming of playing your favorite PC games on the toilet without actually bringing your desktop into the bathroom with you, you’re in luck. Steam’s Link app for Android, which lets you stream titles to your phone over Wi-Fi, is now available in beta on Google Play – and I’m happy to report that it works as advertised.

As long as your PC and phone are on the same Wi-Fi network, Steam Link will be able to beam games to your device. Naturally, the more powerful your hardware and connection are, the better your experience will be: Valve recommends connecting your PC to the web via an ethernet cable, and ensuring your phone is using your router’s 5GHz band if possible.
