As chosen in this thread God Eater 2 will be given away.

Here is a puzzle

sgtools rules apply, all wins activated, no vac and no multiple wins.

Giveaway is open for 2 days

Edit:

I'm not adding a hint for number 2, it's an extremely easy answer to find.

Question 1 has been changed slightly thanks to Chronicdiscord correcting me on something.

A fifth answer has been added to 3 as many have requested it in the GA page.
