Classic solitaire has several named areas, but you only need a few plain rules to begin. Your goal is to move every card into four ordered suit piles, starting with each ace.
The four parts of the table
The tableau is the seven-column working area. The foundation is the set of four finished suit piles. The stock holds unused cards, and the waste shows cards drawn from it.
You spend most of the game making useful space in the tableau.
Build down and alternate colors
In the tableau, place a lower card on a card of the opposite color: a black eight can hold a red seven. A run of correctly ordered cards can move together. Only a king can enter an empty column.
Foundations work in the other direction. They build upward by suit, from ace to king.
Move with a reason
Turning over a hidden tableau card is usually more valuable than sending a low card to the foundation immediately. Before moving, ask what the move reveals or frees.
Undo is part of learning. In a thoughtful digital solitaire game, using it is not a penalty; it is a way to understand why a promising move closed the board.
