🎮 About Tetris

Tetris is one of the most famous video games in history, created by Russian programmer Alexey Pajitnov in 1984. Pieces of seven different shapes fall from the top, and your job is to move and rotate them to complete full rows that vanish for points. The more rows you clear, the higher the level and the faster the pieces fall. The Salleeny version works with touch on phones and the arrow keys on computers.

💡 Tips to win

• Leave one column empty on the side and wait for the long piece to clear four rows at once.
• Always check the next piece and plan where it will go.
• Keep the surface as flat as possible and avoid deep, narrow holes.

🧠 What it builds

Studies show Tetris builds visual-spatial skills and quick decision-making. It helps children picture shapes and rotate them in their mind, a skill that matters in maths and engineering.

❓ FAQ

How do I rotate on a phone?
