Project Overview

The Tetris Game is a classic falling block puzzle game recreated for the web. Different shaped blocks (tetrominoes) fall from the top of the screen, and the player must rotate and move them to fit into rows. When a row is completely filled, it disappears, and the player earns points. The game ends when the blocks stack up to the top of the screen.

This project is ideal for final-year Computer Science students because it demonstrates real-time game mechanics, animations, collision detection, algorithms, and scoring systems using web technologies.

Key Features

1. Tetromino Shapes

   • All standard Tetris shapes (I, O, T, L, J, S, Z).

   • Each shape can rotate 90° clockwise/counterclockwise.

2. Game Board

   • 10x20 grid for block placement.

   • Blocks fall step by step with adjustable speed.

3. Controls

   • Arrow keys for left/right movement.

   • Up arrow (rotate), Down arrow (drop faster), Spacebar (hard drop).

4. Line Clearing Mechanism

   • When a row is completely filled, it disappears.

   • Above rows move down, and the score increases.

5. Scoring & Levels

   • Points awarded based on the number of lines cleared at once.

   • Game speed increases with higher levels for added difficulty.

6. Game Over Condition

   • Game ends when tetrominoes stack up to the top of the grid.

7. UI Features

   • Display of next upcoming tetromino.

   • Scoreboard and level tracker.

   • Pause/Resume functionality.

8. Optional Multiplayer Mode

   • Two players compete with synchronized boards.

   • Clearing multiple lines can send obstacles to opponent.

Technology Stack

• Frontend: HTML, CSS, Bootstrap, JavaScript (for game logic and rendering).

• Backend (optional for multiplayer/leaderboard): Node.js (Socket.io for real-time), PHP, or Java.

• Database (optional): MySQL / MongoDB (to store high scores and player history).

How It Works

1. Game Initialization

   • Grid is generated.

   • A random tetromino spawns at the top center.

2. Gameplay Loop

   • Tetromino automatically falls downward.

   • Player can move left/right, rotate, or drop it.

   • If it collides with bottom or existing blocks, it locks in place.

3. Line Clearing

   • System checks for filled rows.

   • Filled rows are cleared, and player earns points.

   • Speed increases after a set number of cleared lines.

4. Game End

   • If new tetromino cannot spawn (because the grid is filled), the game ends.

   • Final score is displayed, and leaderboard updates if implemented.

Enhancements (Optional)

• Hard Drop & Ghost Piece: Shows where the block will land.

• Themes & Skins: Classic, neon, or retro designs.

• Mobile Version: Swipe controls for rotation and movement.

• AI Bot: Implement AI that plays Tetris automatically.

• Multiplayer Tournament: Global scoreboard and friend battles.
