Solitaire (Klondike) has no opponent – you "win" by moving all cards to the four foundation piles (Ace to King by suit). Many deals are unwinnable, but strategy improves odds.
Key Strategies
Prioritize foundations: Move Aces and build up suits ASAP – frees tableau space.
Empty tableau columns: Only Kings can fill empty columns – create them deliberately.
Expose face-down cards: Always prefer moves that flip new cards.
Use the waste pile strategically: Don't just cycle – look for moves to tableau/foundations.
Delay moves that don't reveal cards: Sometimes holding a playable card is better.
