This is quite far from the truth. FreeCell is one of the few solitaire card games where all of the cards are face up at the start. You can win most of the games you play. Some games are easy to win. Most offer interesting challenges.
Some games are very difficult.
A chessmaster said once that chess is like life. Though FreeCell is a puzzle-solving game, not a battle between two people, the same observation might be made about it. So the next time you berate yourself for spending too much time at the game, remember that you have received some good training. FreeCell is superior to other solitaires. The difficulty of the deal in a particular game is not under the player's control, but after the cards are out, everything depends on skill.
