What is a challenge? Can anyone challenge me?

Question

Is it a set of predefined questions or?
If anyone can challenge me, what happens if I don't accept the challenge?

Answer 1

Those who decline challenges are either weenies or Hatsy Rei.

Most of them are Hatsy Rei. =^=

Answer 2

yes, it's a bunch of questions. you need to get more correct than your opponent to win. if you don't accept a challenge, nothing will happen. however ValentinHacker will think you're a weenie.

Answer 3

if you want to get high xp fast and new to the challenge, challenge higher level person around level 10 or 11 so you will get high xp if you do win. And will get bonus even if you lose. So after some wins start challenging the person on the same level.

Answer 4

But it would be no use for ValentinHacker to challenge someone like this because of the change
