Easy tweaks

Board size: change the dropdown options or default 15×15.
Cell size: adjust --cell-size in CSS.
Use X/O instead of stones: replace renderStone() to insert text and style it.

If you want, I can also provide: single-player vs AI, “exactly five” win rules, move history/undo, or mobile-friendly drag-to-pan on large boards.

·Google·35.3s·2:50 PM·#3

Of course! Here is a complete, working implementation of a Luffarschack (Five in a Row) game using plain HTML, CSS, and JavaScript.

The solution is broken down into three files: index.html (the structure), style.css (the design), and script.js (the game logic).

How to Use

Create a new folder for your project.
Inside that folder, create three files: index.html, style.css, and script.js.
Copy and paste the code from each section below into the corresponding file.
Open index.html in your web browser to play the game.

1. HTML (`index.html`)

This file sets up the basic structure of the game: a title, a status message area, a container for the game board, and a reset button. The board itself will be generated by JavaScript.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Luffarschack (Five in a Row)</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <div class="game-container">
        <h1>Luffarschack / Five in a Row</h1>
        <div id="status" class="status-message">Player X's turn</div>
        <div id="game-board"></div>
        <button id="reset-button">Reset Game</button>
    </div>
    <script src="script.js"></script>
</body>
</html>

2. CSS (`style.css`)

This file provides a simple and clean design for the game board, cells, player markers, and status messages.

body {
    font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;
    display: flex;
    justify-content: center;
    align-items: center;
    height: 100vh;
    margin: 0;
    background-color: #f0f0f0;
}

.game-container {
    text-align: center;
}

#game-board {
    display: grid;
    /* Adjust grid-template-columns for board size */
    grid-template-columns: repeat(15, 30px);
    grid-gap: 2px;
    margin: 20px auto;
    background-color: #999;
    border: 2px solid #333;
    width: fit-content;
}

.cell {
    width: 30px;
    height: 30px;
    background-color: #fdfdfd;
    display: flex;
    justify-content: center;
    align-items: center;
    font-size: 24px;
    font-weight: bold;
    cursor: pointer;
    transition: background-color 0.2s;
}

.cell:hover {
    background-color: #e0e0e0;
}

/* Player marker styles */
.cell.x {
    color: #007bff; /* Blue for X */
}

.cell.o {
    color: #dc3545; /* Red for O */
}

.status-message {
    font-size: 1.5em;
    margin-bottom: 10px;
    height: 30px;
}

#reset-button {
    padding: 10px 20px;
    font-size: 1em;
    border: none;
    border-radius: 5px;
    background-color: #28a745;
    color: white;
    cursor: pointer;
    transition: background-color 0.2s;
}

#reset-button:hover {
    background-color: #218838;
}

3. JavaScript (`script.js`)

This is the core of the game. It handles board creation, player turns, click events, and win detection.

document.addEventListener('DOMContentLoaded', () => {
    const boardElement = document.getElementById('game-board');
    const statusElement = document.getElementById('status');
    const resetButton = document.getElementById('reset-button');

    const BOARD_SIZE = 15; // Standard Gomoku board size
    let currentPlayer = 'X';
    let gameBoard = [];
    let gameOver = false;

    // Initialize the game
    function initGame() {
        currentPlayer = 'X';
        gameOver = false;
        statusElement.textContent = `Player ${currentPlayer}'s turn`;
        boardElement.innerHTML = '';
        gameBoard = Array(BOARD_SIZE).fill(null).map(() => Array(BOARD_SIZE).fill(null));

        // Create the grid
        for (let row = 0; row < BOARD_SIZE; row++) {
            for (let col = 0; col < BOARD_SIZE; col++) {
                const cell = document.createElement('div');
                cell.classList.add('cell');
                cell.dataset.row = row;
                cell.dataset.col = col;
                cell.addEventListener('click', handleCellClick);
                boardElement.appendChild(cell);
            }
        }
    }

    // Handle a player clicking on a cell
    function handleCellClick(event) {
        if (gameOver) return;

        const cell = event.target;
        const row = parseInt(cell.dataset.row);
        const col = parseInt(cell.dataset.col);

        // Check if the cell is already taken
        if (gameBoard[row][col]) {
            return;
        }

        // Place the marker
        gameBoard[row][col] = currentPlayer;
        cell.textContent = currentPlayer;
        cell.classList.add(currentPlayer.toLowerCase());

        // Check for a win
        if (checkWin(row, col)) {
            gameOver = true;
            statusElement.textContent = `Player ${currentPlayer} wins!`;
            return;
        }

        // Switch players
        currentPlayer = currentPlayer === 'X' ? 'O' : 'X';
        statusElement.textContent = `Player ${currentPlayer}'s turn`;
    }

    // Check for a win condition from the last move
    function checkWin(row, col) {
        const directions = [
            { dr: 0, dc: 1 },  // Horizontal
            { dr: 1, dc: 0 },  // Vertical
            { dr: 1, dc: 1 },  // Diagonal (top-left to bottom-right)
            { dr: 1, dc: -1 }  // Diagonal (top-right to bottom-left)
        ];

        for (const { dr, dc } of directions) {
            let count = 1; // Count includes the piece just placed

            // Check in the positive direction (e.g., right, down, down-right)
            for (let i = 1; i < 5; i++) {
                const newRow = row + i * dr;
                const newCol = col + i * dc;
                if (isValid(newRow, newCol) && gameBoard[newRow][newCol] === currentPlayer) {
                    count++;
                } else {
                    break;
                }
            }

            // Check in the negative direction (e.g., left, up, up-left)
            for (let i = 1; i < 5; i++) {
                const newRow = row - i * dr;
                const newCol = col - i * dc;
                if (isValid(newRow, newCol) && gameBoard[newRow][newCol] === currentPlayer) {
                    count++;
                } else {
                    break;
                }
            }
            
            if (count >= 5) {
                return true;
            }
        }
        return false;
    }

    // Helper function to check if a cell is within the board boundaries
    function isValid(row, col) {
        return row >= 0 && row < BOARD_SIZE && col >= 0 && col < BOARD_SIZE;
    }

    // Event listener for the reset button
    resetButton.addEventListener('click', initGame);

    // Start the first game
    initGame();
});

Code Breakdown

initGame(): This function sets up everything. It resets the game state variables (currentPlayer, gameOver), clears the board, creates a new internal 2D array gameBoard to track moves, and dynamically generates the HTML div elements for each cell in the grid.
handleCellClick(): This is triggered when a player clicks a cell. It checks if the move is valid (i.e., the game isn't over and the cell is empty). If it is, it updates both the internal gameBoard array and the visual display.
checkWin(row, col): This is the most important function. Instead of checking the entire board after every move, it only checks around the piece that was just placed.
- It defines four directions (horizontal, vertical, and two diagonals).
- For each direction, it counts consecutive markers belonging to the current player, starting from the last move and extending outwards in both ways along that line.
- If the count reaches 5 or more in any direction, it returns true, indicating a win.
isValid(row, col): A simple helper function to ensure we don't try to check for markers outside the board's boundaries, which would cause an error.

What's Included

Feature	Details
Board	Configurable 15×15, 17×17, or 19×19 grid styled like a Go/Gomoku board
Gameplay	Click to place alternating black/white stones
Win Detection	Checks all 4 directions (horizontal, vertical, both diagonals) from the last-placed stone
Win Highlight	Winning stones glow and pulse with animation
Draw Detection	Detects when the board is completely filled
Scoreboard	Tracks wins for each side and draws across games
Responsive	Smaller stones on mobile screens
Zero dependencies	Pure HTML + CSS + JS in a single file

How to Use

Copy the entire code into a .html file
Open it in any modern browser
Click any intersection to place a stone — players alternate automatically
First to get five in a row (any direction) wins

Key Design Decisions

Win check is O(1) per move — only scans outward from the last-placed stone in 4 directions (max 8 cells checked per direction), not the entire board.
IIFE wrapper keeps all variables out of global scope — safe to embed alongside other scripts.
CSS radial-gradient stones give a 3D appearance without any images.
