Tetris
Stack and rotate falling blocks to clear full lines. The legendary puzzle game that never gets old.
How to Play Tetris
Tetris is the legendary block-stacking puzzle game. Differently shaped pieces called tetrominoes fall from the top of the playfield, and your job is to rotate and position them to form complete horizontal lines. Each completed line clears from the board and earns points. The pieces fall faster as you progress, so quick thinking is key. The game ends when the stack reaches the top.

Tips & Strategy
- Keep your stack flat and avoid leaving deep single-column gaps.
- Save a tall vertical gap for the I-piece to clear four lines at once.
- Clear lines steadily rather than risking a tall, unstable stack.
- Rotate pieces early so you're not rushed as they speed up.
Frequently Asked Questions
How do I score the most points?
Clearing multiple lines at once scores far more than clearing them one at a time — four lines at once is the maximum bonus.
When does Tetris end?
The game ends when newly spawned pieces can no longer fit because the stack has reached the top of the board.
What are the pieces called?
The seven shapes are called tetrominoes, each named after the letter it resembles: I, O, T, S, Z, J and L.
