Dr Tetsuos warning. This game is highly addictive. Play at your own risk. This is Dr Tetsuo. Dr Tetsuo is doing research on logical thinking and, in the process, is hoping to find some bright minds that excel above others. To achieve this, he has devised a whole multitude of diagram puzzles, called Sudoku, to test those willing to take up his challenge. Sudoku has been around for decades, but only now has it gained worldwide popularity. The rules are simple, fill in the missing numbers within the diagram with a digit between 1 and 9. However, each row, column, and region (one of nine subgrids within the whole diagram) can contain the digits 1 through 9 only once. You get a few digits already placed within the diagram, called givens, but the rest is up to you.
