📖 About Tetr.io
The ultimate online multiplayer Tetris game. Compete with friends in real-time and master the art of stacking blocks!
🎮 How to Play
TETR.IO is a modern online stacker game based on classic Tetris mechanics. Stack falling blocks (tetrominoes) to create complete horizontal lines - when a line is filled, it clears and you earn points. In multiplayer modes, clearing lines sends "garbage" lines to your opponents. Be the last player standing to win!
The game features SRS+ rotation system (modified SRS with improved I-piece kicks), adjustable tuning settings including DAS and ARR, and both soft drop and hard drop mechanics.

🎯 Strategy Guide for Tetr.io
Getting Started
Focus on completing lines rather than building tall stacks. Keep your board flat to give yourself more placement options. Learn the basic piece rotations and practice until they become muscle memory. Start with 40 Lines mode to practice speed, then try Blitz for score attack practice.
Advanced Tips
- T-Spins: Learn to set up and execute T-Spin Singles, Doubles, and Triples for efficient garbage sending
- Perfect Clears: Clearing the entire board awards massive points and sends heavy garbage
- Combos: Consecutive line clears increase your attack multiplier significantly
- Downstacking: Learn to clear garbage lines efficiently when your board gets messy
- Targeting: In multiplayer, target players who are close to topping out or who are attacking you
Common Mistakes to Avoid
Don't create tall uneven stacks that limit your options - keep it flat. Don't panic when garbage appears; focus on clearing one line at a time to uncover the garbage hole. Don't forget to use the Hold piece strategically. Avoid using hard drop blindly - sometimes soft dropping gives better placement. Don't ignore your opponents' boards in multiplayer - awareness is key.
