«Tabletop mode» lets you bump out the Switch's rear kickstand and play holding the detached left and right Joy - Cons in either hand, or lend one to a friend and if turned sideways, they work like standard controllers. (fortune.com)
If your hands get tired in this mode, you can slide the Joy - Cons up and off (a tiny release button behind each lets them disengage), prop the Switch on a flat surface with its rear kickstand, then continue playing wirelessly, your hands free to roam like creatures loosed from cages. (fortune.com)
Decouple the controllers from its sides, pop the rear kickstand and it's on a table. (fortune.com)
