An interactive Sudoku game presents a 9×9 grid where players fill empty cells with numbers 1 through 9, following the classic puzzle rules. The board is rendered as an HTML grid, with cells styled through CSS and interactivity managed by JavaScript. The game offers multiple difficulty levels, a timer, and a hint system. The core logic relies on custom JavaScript classes and functions, including backtracking algorithms for puzzle generation and solving, while the user interface responds to clicks and keyboard input.

Sudoku Game

An interactive Sudoku game implemented with HTML, CSS, and JavaScript.

Features

  • Three difficulty levels: Easy, Medium, and Hard
  • Timer to track your solving speed

  • Hint system to help when you're stuck
  • Check your progress or reveal the solution

How to Play

  1. Select a difficulty level and click "New Game" to start
  2. Click on an empty cell, then either:
    • Click a number in the number pad
    • Use your keyboard to enter a number (1-9)
    • Use 0, Delete, or Backspace to clear a cell
  3. Use arrow keys to navigate between cells
  4. Special movements:
    • Press Q to move diagonally up and left
    • Press E to move diagonally up and right
    • Press A to move two cells to the left
  5. Click "Check" to verify your current entries
  6. Click "Hint" if you need help with a cell
  7. Click "Solve" to see the complete solution

The timer tracks how long it takes you to complete the puzzle. Try to beat your best time!

Sudoku

The visualization displays a Sudoku puzzle grid, where each cell contains a number from the provided data set. It shows the puzzle’s initial state with givens (nonzero digits) and empty cells (zeros) laid out in a 9x9 matrix. The grid is rendered using D3.js, with `d3.forceSimulation` positioning the cells and `d3.select` handling DOM updates. The numbers are drawn as text elements, while the grid lines are created via SVG rectangles and paths. The data originates from a plain text file (`sudoku.txt`) parsed into an array, and the code uses standard SVG attributes for styling and layout.

Fork of React Tailwind Starter

An interactive Sudoku game built with React 19 and Tailwind CSS 4 lets users fill a 9x9 grid with digits 1–9 across three difficulty levels. The interface displays the board, highlights selected cells, and provides buttons for reset and auto-solve. Puzzle generation, move validation, and the backtracking solver come from the `generateSudoku`, `isValidMove`, and `solveSudoku` functions in `utils/sudokuLogic.js`. React state manages the board, original puzzle, selection, and win detection, while CDN-imported React and Tailwind power the responsive UI.

Sudoku solver in rust

A Sudoku solver implemented in Rust displays a completed 9x9 puzzle grid as a console output, replacing empty cells with solved digits. The code models the board as a 2D array of characters and converts it to integers, then uses a backtracking algorithm with constraint propagation to find the solution. The `solve_step` function recursively tries candidate numbers, while `get_possible_numbers` checks row, column, and 3x3 subgrid constraints to filter valid options. The final result prints the solved board row by row using standard Rust formatting and I/O operations.

A children's crossword puzzle displays an 11-by-11 grid of letter cells with across and down clues listed alongside. The game uses plain JavaScript and the Document Object Model (DOM) to render the interactive grid, manage user input, and highlight words. Clicking a clue highlights the corresponding word in the grid, while the "Check Answers" and "Show Solution" buttons compare user entries against the embedded word list. The interface relies on CSS grid for layout and event listeners for navigation and validation.

Sudoku solver

This example shows a Python implementation of a Sudoku solver that finds a complete solution for a given 9x9 puzzle. The code defines a `Solution` class with a recursive backtracking algorithm in `solve_step`, which selects the cell with the fewest possible candidates and tries each valid number until the board is filled. It uses a `get_possible_numbers` method to compute remaining digits by checking row, column, and 3x3 square constraints. The solver modifies the board in place and is verified against an expected solution using test functions.

Solitaire

A solitaire pegboard game rendered as an SVG using D3 version 6, where players click brown pegs to select them and then click highlighted purple target positions to jump and remove pegs. The board is a 9x9 grid with a cross-shaped play area, and the scoreboard displays the remaining pegs. The code uses D3’s `scaleLinear`, `selectAll`/`data` joins, and event handlers for click interactions, with a restart button and a "GAME OVER" message when no legal moves remain.

This interactive word search game displays a 15x15 grid filled with letters and a list of fifteen hidden animal, nature, and food-related words. The JavaScript algorithm randomly places words horizontally or vertically before filling empty cells with random letters. Users select words by clicking and dragging across cells in straight lines, with the DOM `mousedown`, `mouseenter`, and `mouseup` events tracking the selection. The grid uses CSS Grid for layout, and a "New Game" button regenerates a fresh puzzle.

Fork of wordsearch fun

This interactive word search puzzle displays a 15x15 grid of letters with 15 programming-related terms hidden horizontally, vertically, or diagonally. Players click and drag across the grid to select letter sequences, with valid words receiving permanent green highlighting and appearing crossed off in the word list. The JavaScript implementation uses DOM manipulation and event listeners for mouse interactions, while CSS grid layout structures the puzzle board. A "New Game" button regenerates the puzzle with randomly placed words and fills remaining cells with random letters.
