Puzzles R too hard for me

Although I would generally recommend you reference the guide mentioned above and just move on and enjoy the rest of the game, if you like puzzles in general, it's better to learn how Sudoku works, also as mentioned above.  I say this because I've always avoided Sudoku puzzles (simply not wanted to learn how they work).  I figured out myself how the Remnant puzzles worked and how easy they became once you learned the strategy.  Then I found out they were based off Sudoku puzzles.  Now I love Sudoku puzzles  🙂
