"FreeCell"的定义和意义

What is "FreeCell"?

FreeCell is a popular single-player card game that became well-known in the 1990s, especially after being included in Microsoft Windows. It is played with a standard deck of 52 cards, where the goal is to move all the cards to four foundation piles, sorted by suit and in ascending order from Ace to King. The game is played on a layout with eight columns of cards, and players can move cards between the columns or to free cells, which are four empty spaces that can temporarily hold a single card. Cards can only be moved to a column if they are placed in descending order and alternate in color. Unlike many other card games, FreeCell does not rely on luck as much, as almost every game can be solved with the right strategy. The game ends when all the cards are arranged correctly or no further moves are possible.
