How to Play SudokuIQ #3 (Letter Sudoku)

In this puzzle, the numbers from 1 to 9 are encrypted using letters of the Latin (English) alphabet according to a simple code key.

Each vertical module – that is, three adjacent columns (1–3, 4–6, 7–9) – uses a different set of letters to represent the digits 1 to 9.

How to solve it?

Check the code table to see which letter corresponds to each digit in the correct vertical module.

Fill the grid with letters so that, after decoding, every number from 1 to 9 appears exactly once in each row, column, and 3×3 square.

The rules are identical to regular Sudoku – the only difference is that instead of numbers, you write the corresponding letters according to the code table.

Tip: You can refer to the code table while solving – simply find the correct column and row to determine the matching letter.

Your goal:
Complete the entire grid so that, after decoding, each digit from 1 to 9 appears once in every row, column, and 3×3 square.
