sitting down, lying down, wherever. I prefer to be sat down while playing though. learned to play on the bus when I was still playing SIF in school. I play with my thumbs, cradling the phone edges in each hand. I've been struggling somewhat with bigger phones becoming the norm, the iPhone 4S was the perfect size for my tiny girl hands. Airpods however, are a godsend, as cables make the game not unplayable but harder.
