Reversi Multiplayer Version

🎯 About This Game

This project implements the classic Reversi game as a multiplayer version. If you like, you can also add additional spectators to the game.

📖 Rules of Reversi

Reversi: Reversi is a two-player strategy game played on an 8×8 board with discs that are black on one side and white on the other.

Setup: In the original version, the game begins with four discs placed in the center of the board in a square pattern: two white discs and two black discs arranged diagonally. The alternative version places them side by side, and in the XOT version, a couple of moves are executed to offer more variety in the middle stages of the game.

Gameplay: Players take turns placing discs on the board with their color facing up. Black typically moves first. A legal move must flank at least one opponent's disc between the newly placed disc and another disc of the player's color (horizontally, vertically, or diagonally). All flanked opponent discs are then flipped to the current player's color.

Passing: If a player has no legal moves available, they must pass their turn. If both players have no legal moves, the game ends.

Winning: The game ends when the board is full, or neither player can make a legal move. The player with the most discs of their color on the board wins. Ties are possible.

Key Strategy: Corner positions are highly valuable as they cannot be flipped. Players aim to control the board while limiting their opponent's options.

🎮 How to Play

Initiating Multi-Player: Find yourself a playing partner and agree upon a room name. The person who creates the room determines who starts the game. The host can also determine whether to play the traditional X setup, the alternative side-by-side configuration, or one of the Xot configurations. The first other person who enters the room will be the playing partner. If desired, additional spectators may be allowed.

XOT - Configurations: These configurations are special start configurations that offer more variability by having the game already started with some prefabricated move. These moves are obtained as the short list from the website of Matthias Berg.

Starting the Game: At the beginning, you'll be presented with a choice screen where you select your color and, therefore, whether you want to start the game.

Making Moves: During the game, you can already see the crosses on the board to see which options are available to you. You place a disc by clicking on the field.

Passing: If you have to pass, the computer automatically continues. If the computer passes, you can continue with your next move.

Game End: When the game ends, the winner is shown at the top of the screen. By simply clicking on it, you can restart with the color selection process.

⚙️ Technical Details

The game is built entirely in Rust using the Macroquad framework and compiled to WebAssembly. The network part uses dedicated technology:

• Websockets:The communication is done over websockets to be able to establish connections in all environments.
• Client Hosted Server: The game host is also running in a browser on the client side.
• Tokio / Axum Relay Server: Beside the web server, we host a dedicated server based on Tokio/Axum to establish communication between different browsers.

💡 Strategy Tips

• Capture Corners: Corner positions can never be flipped - they're the most valuable positions
• Edge Control: Edges provide more stability than central positions
• Mobility Advantage: Try to maintain more move options than your opponent
• Early Restraint: It's often not advantageous to have many discs early in the game
• Avoid X-Squares: The squares diagonally adjacent to corners (X-squares) should be avoided as they give your opponent access to corners
