I changed 2 letters only. And only the first one in the original sequence

#1 hint:

some of the sequences are swapped within the same key.

So we have to guess which of the second key sequences you changed the first letter of?

and then we have to mix and match the sequences from the first and second keys in a
6-4-6-4-6 order and hope to get it right?

I've tried 240 of the 1440 possibilities... no luck

1440? there should only be like 12 possibilties lol

It is 6-4-6-4-6
There are 6 versions of the 6, and 4 versions of the 4.
So, one must choose 3 from the 6 and 2 from the 4. Then they must arrange them in every possible order.
So 6C3 * 4C2 * 3! * 2! if my math is correct.
20*6*6*2
=1440

EDIT: At first I used a silly online calculator that allowed repetition, so my number was higher.

now only that, but you have to guess which is the "first letter" he shifted
this varies the possibilities SO MUCH

It would be hilarious if actually the key you made to hide the original key would work, haha. :-) Good luck and have fun ridd'ling people.

Pretty sure the 1440 is right, though saying it's 6c3*4c2 is wrong.

You have three slots, 6 choices -> 6*5*4
You have two slots, 4 choices -> 4*3
Total = 6*5*4*4*3 = 1440

edit: numlock ninja'd me by fixing his math

grrr 1440 possibilities . . . (6 choose 3 * 4 choose 2) I will continue to copy paste my answers produced through prolog.

Blizzard signs me out every so often for trying so many keys (up to 50 now...)

actually, it's 43200 different possibilities from the info he's given us thus far, you forgot to take into account that we don't know which 2 of the 6 six-letter sequences he changed the first letter in, so you have to multiply by another (6C2), and that gives 43200
i think

Gonna close this before Blizz starts banning accounts for trying too many keys.
