Except they screwed up the five (needs to be the factorial of the root of nine, not the root of the factorial). And I'm infinitesimally disappointed with the seven.

this much?

1 - .¯9

Only two nines used for the one.

??

Like one o'clock?

Should be 9/9 * .¯9

All the rest of them are made up of three nines.

Ah, I understand now. I'd misread "that" when you wrote "the".

Then ZenGum could be twice as infinitesimally disappointed.

OK, now someone's got to make up a "clock of the beast".
Some, of the terms above will work, but not all.

Only 5 will work like the nines do, as the square root of 6 isn't an integer, and neither is .¯6 (but .¯9 actually equals 1).

Here's a few:
1: 6^(6-6)
2: (6+6)/6
3:
4:
5: 6-(6/6)
6: 6^(6/6) or (6*6)/6
7: 6+(6/6)
8:
9:
10:
11: 66/6
12:

5: 6 - 6/6

(sorry, didn't mean to make yours look like a dupe, I did my edit before I saw your post)

10: 6.¯6/.¯6

This is a bit cheap: 4: 6*.¯66

My head exploded again.

8: (6+6) * .¯6

A bit cheap again:
3: sqrt(6/.¯66)
9: 6/.¯66

So that leaves 12.

Um...

12: 6+6

Duh?
