Rules

Basic rules

  • Setup: 8 tableau columns, all cards face-up

    Columns 1-4 have 7 cards; columns 5-8 have 6 cards.

  • 4 FREE CELLS empty at start (temporary parking)

    Only ONE card per free cell at any time.

    One foundation per suit.

  • Tableau built DOWN alternating COLOR

    Red 7 on Black 8, etc.

  • Move Aces + 2s to foundations quickly

    Immediate progress + tableau cleared.

  • Plan sequences before moving

    Think 3-5 moves ahead.

  • Watch for buried Kings

    Kings underneath obstruct — extract early.

  • Super-moves calculation: (empty cells+1) × 2^(empty columns) cards

    How many cards can move at once.
