Solitaire Classic is like a puzzle with cards! In this game, you have to stack all the cards from the smallest to the biggest on four piles, but there's a trick - they need to be the same suit like all hearts or all spades. And, you can only place a red card on a black one (or vice versa) while you're sorting. It's a game you play by yourself, so it's great when you want some alone time. Also, this game can take a while to win, so it really helps to make a long car ride go quicker!
