There are four open cells and four open foundations. Some alternate rules use between one to ten cells.
Cards are dealt face-up into eight cascades, four of which comprise seven cards and four of which comprise six. Some alternate rules will use between four to ten cascades.
Any cell card or top card of any cascade may be moved to build on a tableau, or moved to an empty cell, an empty cascade, or its foundation.
Complete or partial tableaus may be moved to build on existing tableaus, or moved to empty cascades, by recursively placing and removing cards through intermediate locations. Computer implementations often show this motion, but players using physical decks typically move the tableau at once.
