Dr. Sudoku

Sudoku originally called Number Place, is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 sub-grids 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 unique solution.

Completed puzzles are always a type of Latin square with an additional constraint on the contents of individual regions. For example, the same single integer may not appear twice in the same row, column or in any of the nine 3×3 subregions of the 9x9 playing board.

Dr. Sudoku is a puzzle game that combines elements of Sudoku and logic puzzles. The goal of the game is to fill a 9x9 grid with numbers so that each row, column, and 3x3 box contains all of the numbers from 1 to 9. However, unlike traditional Sudoku, Dr. Sudoku also includes additional clues that help to guide the player in solving the puzzle.

These clues can take a variety of forms, such as:

* Number clues: These clues indicate the sum of the numbers in a particular row, column, or box.

* Symbol clues: These clues indicate the relationship between the numbers in a particular row, column, or box. For example, a clue might indicate that one number is greater than or less than another number.

* Logic clues: These clues provide logical constraints that help to narrow down the possible solutions. For example, a clue might indicate that a particular number cannot be placed in a certain position.

Dr. Sudoku puzzles can vary in difficulty from easy to challenging. The game is a great way to improve your logical thinking and problem-solving skills. It is also a fun and addictive way to pass the time.
