How to play

• Goal: all 52 cards onto the four foundations, each suit Ace to King. Every card is face up.
• Columns: build down in alternating colours (red 7 on black 8).
• Free cells: each holds one card. Only a column’s bottom card goes in; it can come back to a column or a foundation.
• Empty column: any card or run can go there.
• Runs: you can move (1 + empty cells) × 2 per empty column cards at once — “Move” above shows how many now.
• Moving: drag, or tap a card then where it goes. Cards do not come back off a foundation.
• Keys: Tab to a card or place, Enter to pick up and place, Ctrl+Z to undo, Esc to let go.
