Play Tetris Online: A Step-by-Step Guide

Visit an online gaming website that offers Tetris for play. Examples include TetrisFriends.com, TetrisZone.com, and Pogo.com.

Create an account with an email address and choose a username and password. Some websites require a valid email address to verify your account.

Choose the type of game you would like to play. Most websites offer single-player, multi-player, and tournament modes.

Adjust the game settings as desired. Some websites allow you to adjust the speed, difficulty, and music.

Click the 'Play' button to begin the game. Use the arrow keys on your keyboard to rotate and move the blocks.

Line up the blocks to form complete rows. When a complete row is formed, it will disappear and your score will increase.

Try to increase your score as much as possible. If the blocks reach the top of the playing field, you will lose the game.
