I play Solitaire and other card games on my phone to wind down. Some games turn out better for me than others. I can’t win them all, but I’d really like to! My competitive nature compels me to try to win. I discovered a nifty little undo button at the bottom of the screen I can use. If I make a move that doesn’t help me win, I simply undo that move and try a different one. I can undo as many moves as I would like. I can also reset the whole game if it’s going badly.
