Editing FreeCell (section)

=== Supermoves ===
Unlike in many solitaire card games, the rules of Freecell only allow cards to be moved one at a time. Complete or partial tableaus may be moved to build on existing tableaus, or moved to empty cascades, only by a sequence of moves which recursively place and remove cards through intermediate locations. 

For example, with one empty cell, the top card of one tableau can be moved to a free cell. The second card from the top of that tableau can now be moved onto another tableau. Then the original top card can be moved from the cell on top of it.

Such a sequence of moves is called a "supermove". Computer implementations often show this motion<!-- and I bet there's a GIF of this somewhere -->, but players using physical decks typically just move the tableau at once. 

The maximum number <math>C</math> of cards in a tableau that can be moved to another tableau equals the number of empty cells plus one, with that number doubling for each empty cascade: <math>C = 2^M\times (N+1)</math>, where <math>M</math> is the number of empty cascades and <math>N</math> is the number of empty cells.<ref name="stackex">{{cite web |title=solitaire - FreeCell: How many cards can be moved at once? |url=https://boardgames.stackexchange.com/a/45157 |website=Board & Card Games Stack Exchange}}</ref> The maximum number that can be moved to an empty cascade is <math>C/2</math>.<ref name="stackex"/>
