Rules

  1. All 52 cards are dealt face up into eight columns: seven cards in the first four and six in the rest. The four free cells at the upper left each hold one card. The four suit foundations build from Ace to King.
  2. Build columns downward in alternating colors: a red 6 fits on a black 7. Empty columns accept any card or valid sequence. Move only an ordered sequence at a column's exposed end, never a buried individual card.
    How it works: Build columns down in alternating colours: the red six goes beneath the black seven.
  3. Select a card or sequence, then select a destination, free cell or foundation; dragging also works. Selected cards rise and glow, and legal targets gain an outline. Select the same card again or press Esc to cancel. Ranks and suits appear at both corners.
  4. A sequence move is limited to (empty free cells + 1) × 2 to the power of the empty column count. An empty destination column does not count as temporary storage. Occupied free cells reduce carrying capacity; empty columns increase it.
  5. Auto collect moves only currently safe cards to the foundations. Other legal foundation moves remain manual. Undo and redo are repeatable. Hints suggest a legal move using a bounded short search, not a guaranteed complete solver.
  6. The route contains 40 full 52-card starting deals, each with a retained solution replayed through legal moves. Three stars meet a known achievable move target; two use at most 135% of it; any other completion earns one. There is no time limit.
  7. Daily deals use the UTC date. A text seed recreates the same deal. These are locally constructed solvable deals, not Microsoft deal numbers. Changing or redealing a game asks for confirmation once you have moved.
  8. This browser saves your position, undo history and personal results. Rules, pause and leaving the tab stop the clock; time never affects victory. Move all 52 cards to the suit foundations to win.
