Rules & objective
All 52 cards face up in eight columns: seven in the first four, six in the rest. Four cells each hold one card; four foundations build by suit, Ace through King. Columns build down one rank in alternating colours; any movable card can fill an empty column. A whole ordered sequence is a shortcut for legal single-card moves: capacity is(empty cells+1)×2^usable empty columns. Exclude an empty destination column from temporary space. Foundation tops may move back. Collect all 52 to win. A bounded search failure does not prove a deal impossible; random deals are not promised winnable. Hints use public cards only. Card/destination selection previews; confirm, Undo, Reset the same pack or New deal.
Controls
Drag cards and release to place them, or tap a card then its destination. Tap the stock to draw.
Worked example
Free cells and empty columns limit sequence capacity. Create space before moving a long descending, alternating-colour sequence.
