Interactive Sudoku Solver. To set a value, select a cell and type a number. To add a line or region constraint, select and drag; or shift-click. To add a Little Killer constraint, select a diagonal arrow outside the grid. To add other outside clue constraints, select a row or column arrow outside the grid. OR.
🎯 This Python-based Sudoku Solver utilizes the PyGame Library and Backtracking Algorithm to visualize and solve Sudoku puzzles efficiently. With its intuitive interface, users can input and interact with the Sudoku board, allowing for a seamless solving experience.

Run SudokuUI.py. This requires a web browser and the Python package Eel by Chris Knot. The latter can be installed with pip install eel. Numbers can be freely entered into the grid spaces. Non-numeric inputs will be ignored. To delete a character, push delete. If there are any errors in the numbers e.g. duplicate numbers, this will be found while solving. Blue characters are the user's input. Grey characters are computer generated. Solving and displaying results should take less than a second.

A Sudoku in grid form: [8, 9, 0, 0, 7, 0, 0, 1, 0] [6, 2, 0, 0, 0, 3, 0, 5, 0] [0, 0, 4, 0, 0, 0, 0, 0, 0] [0, 6, 0, 0, 4, 0, 2, 0, 0] [0, 0, 0, 0, 8, 5, 4, 3, 0] [0, 0, 0, 1, 0, 0, 0, 0, 0] [0, 0, 2, 7, 0, 0, 5, 0, 0] [9, 0, 0, 2, 0, 0, 1, 0, 0] [5, 0, 0, 4, 0, 0, 0, 0, 0] It can be serialised by concatenating rows instead of stacking them: This is more space efficient for storing multiple Sudokus. The code has functionality to read in serialised Sudokus and convert them to a grid.
To solve even the most challenging of these puzzles, our Sudoku solver only needs to follow three strategies:
1.If a square has only one candidate, place that value there.
2.If a candidate is unique within a row, box or column, place that value there (hidden singles).
3.If neither 1 or 2 is true in the entire grid, make a guess. Backtrack if the Sudoku becomes unsolvable.
The Sudoku Solver also implements other strategies. These can make the code run marginally faster:
•Hidden/naked pairs
•User Interface: Erfan Paslar.
•ny.txt puzzles from https://www.nytimes.com/puzzles/sudoku (no archives).
This project contains an optimized Sudoku solver and puzzle generator for conventional 9x9 puzzles (as well as Sukaku "pencilmark" puzzles with clues given as negative instead of positive literals). It also contains two other solvers with several variations exploring
The solver is open source (MIT license) and available on Github. The solver is based on backtracking as described by Peter Norvig . It uses custom constraints for propagation and a different heuristic (based on the entered constraints) to optimize the search.

Sudoku solver. Sudoku is a logic-based, combinatorial number-placement puzzle. In classic Sudoku, the objective is to fill a 9 × 9 grid with digits so that each column, each row, and each of the nine 3 × 3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contain all of the digits from 1 to 9.
