View source for Deck of Every Card spades puzzle

Getting an '''X of Spades''' card from [[Deck of Every Card (adventure)|Deck of Every Card]] yields a string of letters (letter count equals X).

==Stage One==
For new players, the string is a subset of the common string ''"UJLWTTLEJCCQYOIYMWESZWPWFOBUNKWGULYKDQNADDBWXUWKRRRTBIHXBUMWAIZGEDTHJGGUGEWCCCICOPJTNM"''. It is coded with the [[wikipedia:Vigenère cipher|Vigenère cipher]], the key is ''"ABCDEFGHIJKLMNOPQRSTUVWXYZ"''. The deciphered string reads ''"THIS ONE WAS RELATIVELY EASY GO ASK GRANDPA SEA MONKEE ABOUT STAGE TWO FOR YOUR PERSONALIZED CHALLENGE"'', without spaces.

==Stage Two==
After a player asks [[Grandpa]] about "stage two" the cards start giving subsets of some different string. The new string is different for each player, but the same for the same player. It is coded with the [[wikipedia:Playfair cipher|Playfair cipher]], the key is the player's name. The deciphered string reads ''"GREAT WORK YOU ARE READY FOR YOUR FINAL CHALLENGE ASK ABOUT ??????????? FOR THE LAST STAGE BE SURE TO DESTROY WHEN YOU ARE DONE READING"'', without spaces, where ''???????????'' is replaced by a user-specific password. The password is usually ('''but not always''') an 11-letter long English word (such as "copywriters").

==Stage Three==
After the player asks [[Grandpa]] about the player-specific stage two password the cards start giving subsets of the final string, common for all players. The string is ''"KQAESGDOJDBQCBYQVRSEFATCBMJORWXKCKBVSUYNLICNYBGKUYDIIOOGSHXLEKWROPXYKYSURVCJGYVZCH"''. It is coded with the Vigenère [[wikipedia:Autokey cipher|autokey cipher]], the key is the second half of the plaintext. The deciphered string reads ''"CONGRATULATIONS YOU HAVE COMPLETED THIS PUZZLE GO ASK GRANDPA ABOUT DEEP SPADING FOR YOUR REWARD"'', without spaces.

The result of asking [[Grandpa]] about "deep spading" is [[talking spade]].

Drawing an X of Spades card after this gives you a substring of "YOUAREAGREATSPADE".

==Notes==
*The stage one was [http://forums.kingdomofloathing.com/vb/showpost.php?p=4752659&postcount=76 decoded] on Jul 6, 2015, at that time only the first 3 letters of the ciphertext were unknown.
*The stage two was [http://forums.kingdomofloathing.com/vb/showpost.php?p=4754962&postcount=290 publicly decoded] on Jul 13, 2015.
*The stage three was first [http://forums.kingdomofloathing.com/vb/showpost.php?p=4755662&postcount=399 publicly decoded] on Jul 16, 2015.
*You need to unlock the stage two only once.
*You don't need to draw any cards or own the deck to complete stage 1 and unlock the stage two. However this seems pointless since you have to be able to draw enough cards, and have enough of them be Spades cards, to get enough of the text for the password of stage 2 to be revealed or at least deduced.
*HotStuff [http://forums.kingdomofloathing.com/vb/showpost.php?p=4755074&postcount=322 confirmed] that the stage two password is not always 11 letters long, and that due to an error, some passwords that start with ''T'' will actually start with "a weird ''XT''".
*Known passwords are as short as 5 letters [http://forums.kingdomofloathing.com/vb/showthread.php?p=4765640#post4765640] and as long as ?.
*It's possible to find the stage two password without discovering the whole ciphertext, by encrypting the cleartext with the password part replaced with some characters, then finding out and decrypting known sequences which are not parts of the resulting ciphertext (it's also possible to guess the password knowing only a part of it). Note that the ciphertext part after the password differs for even-length and odd-length passwords. There's an even clearer explanation of that [http://forums.kingdomofloathing.com/vb/showpost.php?p=4755066&postcount=317 HERE].
* It's possible an alternate encoding is dropping, as documented on the Discussion tab.
*You can't skip steps by just entering the stage one and three passwords (the ones which are the same for everybody), you need to first unlock them properly.
