Rules & objective
Arrange 28 cards in three peaks with rows 3/6/9/10. Of 24 stock cards, one starts the waste, leaving 23 without recycling. Only cards uncovered by both children can play; their rank must be one above or below the waste top, regardless of suit. Choose Ace–King wrapping on/off and all-up/covered-down faces; covered cards reveal only after both children are removed. A played card becomes the new waste top; draw when blocked or earlier by choice. Clear all 28 to win, even with stock left. Stock empty plus no legal removal means this line is stuck, with Undo available. Hints search visible cards only and cannot predict stock. Select to preview, then confirm.
Controls
Play directly on the cards or board with mouse or touch. Coordinate selectors are optional keyboard aids.
Worked example
With a top card of seven, an exposed six or eight can be removed. A card still covered by another card is unavailable.
