Tetris is a classic, world-famous tile-matching puzzle video game created by Soviet software engineer Alexey Pajitnov on June 6, 1984.

Control and place different falling geometric shapes (called Tetrominoes) onto a grid. You can rotate and move them horizontally. Completing a full, unbroken horizontal row of blocks clears that row, earning points and creating more space on the board.

When was Tetris made?

Tetris was created and first released on June 6, 1984, in the Soviet Union.

The Tetris brand, logos, and game assets are owned by The Tetris Company, LLC, which manages copyright licensing worldwide.

Why does Tetris help with trauma?

Clinical studies indicate that playing Tetris shortly after experiencing a traumatic event occupies visual processing capacity in the brain, disrupting the formation of vivid, intrusive trauma memories and reducing flashbacks.

On desktop, use the arrow keys, Space, and C/Hold controls. On phones and tablets, use the touch controls below the board. The layout adapts to smaller screens so the play area and controls remain easy to use.

Free Tetris Strategy Tips

Keep the stack low, avoid unnecessary holes, save useful pieces for difficult gaps, and use the Hold feature when the current piece is awkward. As the level rises, make decisions earlier because pieces fall faster.

Tetris Modes and Levels

Choose from multiple levels or switch between Casual and Challenge Mode. The game also includes optional power-ups such as Void Bomb, Gravity Freeze, and Nanobot Repair when enough energy has been earned.

About Tetris

Tetris is a classic tile-matching puzzle game built around falling geometric pieces called Tetrominoes. The core objective is simple: arrange the pieces to complete full horizontal lines and prevent the stack from reaching the top of the board.

OneStepKit provides its own browser-based Tetris implementation with standard movement and rotation alongside custom Gravity Rift mechanics, Challenge Mode, levels, and power-ups. It is an independent game experience and is not an official Tetris product.
