So, Solitaire 1 is a super fun card game where you have to stack all the cards in order! You start with a big pile of cards, and you have to flip them over and match colors and numbers. It's like a puzzle! You can move cards around and try to organize them into neat piles by suit, which are the hearts, diamonds, clubs, and spades. If you get stuck, you can draw new cards to help you out. The goal is to clear all the cards and make your special stacks. It feels like solving a treasure map!
