Based on hint 3:
Are you talking about the word puzzle in the explanation of revision 2 for this puzzle: "Added a
tag to make the puzzle presentable" ?
(Would be similar to how you hid the riddle/puzzle in guess the puzzle #1, albeit a bit more literal...)
Based on hint 2:
As @El-Guest answered in Guess the puzzle, Rev. 2 has a hidden question asking for 2*3, which is 6
More attempts because why not:
The post discovery forehead smacker:
How do I/you make this puzzle presentable?
If that really is the answer, then credits primarily to @ace. If they make an answer post, then it should go to them.
The sillier wild attempt #3:
The first edit also affects the word 'here' and discusses a break tag.
So, "I need a break from here", which can't possibly be true! :P
Wild attempt #2:
I don't see much provided here in the question, so I'm back to looking at your profile. Somehow, you have 9 other SE "accounts" that are all at 101 rep points. Dunno how you pulled that off, but it makes me think this question has something to do with that. Thus my guess is this:
101 * 9 = 909
In your profile, there is the hint "Check the state of matter of the poison".
In the first part, the answer is 6.
6 on the periodic table is carbon, and carbon monoxide is a know issue in homes. It is also a gas.
1. There may not be enough edits yet so I could be missing something.
2. What really gets me is the break tag. So I wouldn't be surprised if my current answer is incorrect.
