Letter Sudoku (often called Word Sudoku) replaces the numbers 1-9 with the letters A-I. The rules are identical to classic Sudoku: each letter from A to I must appear exactly once in every row, column, and 3x3 box. This variant offers a refreshing challenge for those looking for a twist on the traditional number puzzle. Our solver is built to handle this specific format with ease.
Simply use the letter pad or your keyboard to enter the given letters from your puzzle into the grid. Leave the cells you need to solve empty. When you're ready, click "Solve Puzzle," and our algorithm will instantly fill the board with the complete and correct solution, following all the rules of Sudoku.
