The classic Sudoku game involves a grid of 81 squares. The grid is divided into nine blocks, each containing nine squares. The rules of the game are simple: each of the nine blocks has to contain all the numbers 1-9 within its squares. Each number can only appear once in a row, column, or 3×3 box.

An extra rule for the sudoku below is that instead of filling in the numbers 1-9 you have to fill in 9 different letters, other rules remain the same. Fill in the following words on the blue lines: ADDED, ADVENTIVE, AWARD, AVIAN, DRIVE, RENEW, TIRED, TRAIN, and WEIRD. Which nine-letter word can you read in a straight line?
For this sudoku, all letters and blanks have already been filled in the sudoku except for the diagonals. Multiple letters (and a blank) refer to the same number in a classical sudoku. And all groups have the same size, for example, the letters ABC = 1 are all 1 (DEF = 2, … and YZ and a blank = 9). Solve the sudoku after finding out which letters represent the same number. Also, all letters (and a blank) occur with the same frequency in the sudoku. Which mathematical journal can be found on the diagonals?
