Aleph Bet Sudoku!

Sudoku is played over 9x9 grid, in each row there are 9 slots, some of them are empty and need to be filled.

Each row, column and “area” (3x3) should contain the letters Alef throughTet, however:

• Letter can appear only once on each row
• Letter can appear only once on each column
• Letter can appear only once on each area (3x3 slots)

The bottom line: the letter should appear only once a row, column or area.
