Tetris Battle Royale
A multiplayer Tetris Battle Royale game built with HTML, CSS, JavaScript, and Node.js.
Features
- 2-8 Player Multiplayer: Real-time battles via WebSocket
- Battle Royale Mechanics: Clear rows to send garbage to opponents
- Classic Tetris Gameplay: All 7 tetrominoes with standard rotation
- Retro Visuals: CRT scanlines, pixel art font, classic colors
- Multiple Boards View: See all players' boards simultaneously
How It Works
When you clear rows, garbage rows are sent to random opponents:
- 2 lines cleared → 1 garbage row sent
- 3 lines cleared → 2 garbage rows sent
- 4 lines (Tetris) → 4 garbage rows sent
The last player standing wins!
