The definitive five-minute reset puzzle — familiar enough to start instantly, uncertain enough to stay engaging. When you need to clear your head without learning anything new, Solitaire is the correct answer.
Klondike (standard Solitaire) has face-down cards that introduce uncertainty, and roughly 20% of deals are unwinnable. FreeCell deals all cards face-up and has four open holding cells; over 99% of FreeCell deals are solvable with correct play.
