Alphabet Sudoku Medium

Medium Alphabet Sudoku trims the starting letters until simple sweeps stop working everywhere. You will start double-checking letter pairs inside boxes — the exact habit harder levels demand. Every cell takes one of nine symbols: ABCDEFGHI.

How to play Alphabet Sudoku

Play exactly like classic Sudoku, only with letters. Fill the grid so that every row, column and 3×3 box contains each letter from A to I exactly once.

• Each row contains the letters A–I exactly once.
• Each column contains the letters A–I exactly once.
• Each 3×3 box contains the letters A–I exactly once.
• Prefilled letters are fixed clues — everything else you deduce.

Medium Sudoku tips

Medium is where candidate tracking enters the game:

• Keep pencil notes. Use the note mode to record every candidate a cell can hold. From this level up, notes stop being optional.
• Hunt hidden singles. A symbol that fits only one cell of a row, column or box is a certain placement — even when that cell still shows several candidates in your notes.
• Clear naked pairs. Two cells in one unit holding the same two candidates mean no other cell of that unit can take either symbol. Strike them and the unit often collapses.

About Alphabet Sudoku

Alphabet Sudoku swaps the digits 1–9 for the letters A–I. The logic is identical, but scanning feels different: your word-game brain takes over, and pairs like D/F start jumping out the way 4/5 do in a classic grid.

About Sudoku

Sudoku is a logic-based, combinatorial number-placement puzzle. In classic Sudoku, the goal is to fill a 9 x 9 grid with digits so that each column, each row, and each of the nine 3 x 3 subgrids that compose the grid contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.
