About Tetris

Originally released in 1984. Tetris is the timeless puzzle game: rotate falling blocks into complete lines before the stack reaches the top, faster and faster, forever. This game is part of our Calm Games collection. Difficulty: Medium.

How to Play Tetris

Controls: Left/Right to move, Up to rotate, Down to soft-drop, Space to hard-drop

Goal: Clear as many lines as you can and survive the rising speed for a high score.

Tips & Strategy

• Keep your stack flat — bumps create holes that are hard to fix.
• Leave one column open as a well for long I-pieces.
• Clearing four lines at once (a Tetris) scores far more than singles.
• Look at the next-piece preview and plan two moves ahead.
