Simple, dart API for Sudoku puzzles #

sudoku_api simplifies the generation, interaction, and management of Sudoku Puzzles.

Well, how does it do that?

Contains a Built-in solver for generating new puzzles, or solving existing ones

Utilizes and exposes event streams for grid interactions (e.g. cell value changed), and puzzle states

Exposes a bunch of neat, easy to use models manipulating Cells, Positions, Grids, and even Patterns of a Sudoku puzzle

What is Sudoku?

... 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 subgrids (segments) that compose the grid contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.

import 'package:sudoku_api/Puzzle.dart'; void main() { PuzzleOptions puzzleOptions = new PuzzleOptions(patternName: "winter"); Puzzle puzzle = new Puzzle(puzzleOptions); puzzle.generate().then((_) { print("====================================="); print("Your puzzle, fresh off the press:"); print("-------------------------------------"); printGrid(puzzle.board()); print("====================================="); print("Give up? Here's your puzzle solution:"); print("-------------------------------------"); printGrid(puzzle.solvedBoard()); print("====================================="); }); }

===================================== Your puzzle, fresh off the press: ------------------------------------- 9 8 3 4 7 6 9 8 5 1 4 5 4 5 6 9 3 1 2 3 2 2 8 9 8 3 2 7 5 6 2 ===================================== Give up? Here's your puzzle solution: ------------------------------------- 2 9 1 6 3 4 5 8 7 3 4 5 1 7 8 2 6 9 6 7 8 2 5 9 1 3 4 1 2 3 4 6 5 7 9 8 4 5 6 8 9 7 3 1 2 7 8 9 3 1 2 4 5 6 5 1 2 7 8 6 9 4 3 8 3 4 9 2 1 6 7 5 9 6 7 5 4 3 8 2 1 =====================================
