''Free Cell'' is the solitaire card game that Paul Alfille introduced to the PLATO system in 1978. Jim Horne, at Microsoft, changed the name to ''FreeCell'' and reimplemented the game for [[DOS]], then [[Windows]]. This version introduced 32000 numbered deals. (The [http://www.solitairelaboratory.com/fcfaq.html FreeCell FAQ] tells this history.)
 
''Free Cell'' is the solitaire card game that Paul Alfille introduced to the PLATO system in 1978. Jim Horne, at Microsoft, changed the name to ''FreeCell'' and reimplemented the game for [[DOS]], then [[Windows]]. <br>
As the game became popular, Jim Horne disclosed [http://www.solitairelaboratory.com/mshuffle.txt the algorithm], and other implementations of FreeCell began to reproduce the Microsoft deals. These deals are numbered from 1 to 32000. Newer versions from Microsoft have 1 million deals, numbered from 1 to 1000000; some implementations allow numbers outside that range.

As the game became popular, Jim Horne disclosed [http://www.solitairelaboratory.com/mshuffle.txt the algorithm], and other implementations of FreeCell began to reproduce the Microsoft deals. <br>
These deals are numbered from 1 to 32000.
Newer versions from Microsoft have 1 million deals, numbered from 1 to 1000000; some implementations allow numbers outside that range.
 
The algorithm uses this [[linear congruential generator]] from Microsoft C:
Line 11 ⟶ 15:
* Rosetta Code has another task, [[linear congruential generator]], with code for this RNG in several languages.
 
<br>
The algorithm follows:
 
Line 22 ⟶ 27:
# Deal all 52 cards, face up, across 8 columns. The first 8 cards go in 8 columns, the next 8 cards go on the first 8 cards, and so on.
 
::::{| class="wikitable"
!| Order to deal cards
!| Game #1
Line 50 ⟶ 55:
|}
 
Deals can also be checked against [http://freecellgamesolutions.com/ FreeCell solutions to 1000000 games]. (Summon a video solution, and it displays the initial deal.)
(Summon a video solution, and it displays the initial deal.)
 
Write a program to take a deal number and deal cards in the same order as this algorithm. The program may display the cards with ASCII, with Unicode, by drawing graphics, or any other way.

{{FormulaeEntry|page=https://formulae.org/?script=examples/Deal_cards_for_FreeCell}}
 
'''Solution'''
 
There is no need to remove from a deal to be added to another one, it can be performed on a single array. It is and iteration from 52 to 1 indicating the end of the first array, and therefore the start of a second one after each swap. The only inconvenience is that second array contains the information in reversed order, but when it is shown it is also read in reversed order.
 
The number 127,185 is the decimal number of the 🃑 Unicode character.
 
In the Unicode playing cards characters, there is the Knight, between the Jack and Queen suits, which is not used, so it is skipped in the order.
