This trophy is titled "
Sdorw Ytfif" and it requires you to complete a puzzle by finding every word backwards.
For this trophy, most any puzzle will work. It's rather straight forward, find all of the words backwards. The issue is that certain puzzles will have words such as PEEP or NUN. That makes it impossible to know which is the correct direction, if there even is a direction on a palindrome in the game.
With that said, I'm leaving the solution to the
Big Words puzzle from the third page, middle column, at the bottom. It's pretty straight forward and no palindromes.
