What is Tetris?

At its core, Tetris is a block-stacking game where players must arrange falling Tetrominoes (geometric shapes made of four square blocks) to form full horizontal lines. Once a line is completed, it disappears, earning you points and clearing space for more blocks. Sounds easy? As you progress, the blocks fall faster, testing your reflexes and puzzle-solving skills.

How to Play Tetris

Objective: Fit the falling Tetrominoes into complete rows. When a row is filled, it clears automatically and awards points.

Controls:

• Left/Right Arrow: Move blocks sideways
• Up Arrow: Rotate the block
• Down Arrow: Speed up the fall

The game ends when the blocks reach the top and there’s no space left to drop new pieces — so stay sharp!

Tetris Tips & Strategies to Master

Want to get better at Tetris? Try these pro tips:

• Keep the stack flat: A flat, even stack helps you stay in control and avoid tricky gaps.
• Save the I-shaped Tetromino: Use this piece to clear four lines at once for a powerful "Tetris" move.
• Plan ahead: Watch the upcoming pieces queue to prepare your moves in advance.
• Master rotations: Learn how each Tetromino behaves when rotated. This skill is key to fitting blocks into tight spots.

 Why is Tetris So Addictive?

Tetris is more than just a game—it’s a mental workout. Research shows it improves spatial reasoning, problem-solving, and even relieves stress. Its addictive nature comes from a mix of quick rewards, escalating difficulty, and the psychological pull of wanting to complete just one more line. That “just one more round” feeling? That’s the Zeigarnik Effect at work.
