Minecraft for Android, iOS, and Windows 10 is getting pistons

Pistons are coming to Minecraft. No, not the Detroit Pistons — although that would be pretty great.

Minecraft developer Mojang announced today that it will release piston blocks for free for the Pocket and Windows 10 versions of the building-focused game. Pistons can push away other blocks, which can create complex machines like automatically opening doors. Pistons will be in the upcoming The Friendly Update. It doesn’t have a release date, but Mojang says it is coming soon. Free updates like this keep players engaged and entertained. It’s one of the reasons Minecraft has sold more than 100 million copies on all of its many platforms, which also include PlayStation 4, Xbox One, and Wii U.
