Classic Solitaire, or Klondike, is a timeless single-player card game. Arrange a standard deck of cards in ascending order by suit, employing strategic moves and stacking, to ultimately organize all cards into four foundation piles.

In Classic Solitaire, start with a shuffled standard deck. Arrange cards in seven columns, alternating face-down and face-up cards. Build descending sequences by alternating colors. Move cards between columns to uncover hidden ones. Aim to organize all cards into four foundation piles, one for each suit, in ascending order.
