How is it possible to lose points playing solitaire?

In solitaire, players typically lose points by making moves that violate the game's rules or by failing to complete the game within a specific number of moves. For example, in some variations, moving cards incorrectly or making unnecessary moves can result in point deductions. Additionally, if a player runs out of moves before completing the game, they may receive a penalty. Overall, point loss in solitaire often reflects poor strategy or decision-making during gameplay.
