Steps opens with a seven-column staircase of 28 cards, only seven of them visible. A 76-card draw-one stock supplies the rest of the two decks.
Empty steps can take any run
Build columns down in alternating colors. An ordered alternating-color sequence can move together, and any card or legal run may occupy an empty column. Hidden cards turn over when uncovered. Eight foundations build upward by suit from ace through king.
The stock will not come back
Only the exposed waste card can move, and there is no redeal. Before drawing again, check whether that card can release a hidden tableau card or become a useful receiver. Duplicate ranks let you choose between copies; favor the one that opens another move instead of simply making a longer column.
