Normal sudoku rules apply.

Either the orange 'F' or the blue 'F' is "correct." The same concept applies for "L," "I," and "P."

If a letter is correct, it contains a non-repeating set of digits that sum to 20 and any line that passes through it is a valid clue.

Any line that passes through an incorrect letter must be wrogn (wrong in every instance).

Adjacent digits along a valid green line differ by at least 5.

Digits along a valid purple line form a set of consecutive digits in any order.

For clarity, adjacent digits on a wrogn green line differ by at most 4 and no two digits on a wrogn purple line are consecutive. Clues that do not make contact with any letters are valid.
