Tetris is a classic puzzle game that challenges your spatial and logical skills. The game consists of falling blocks of different shapes and colors, called tetrominoes, that you have to arrange and fit into the gaps at the bottom of the screen. You can move the blocks left or right, and rotate them by 90 degrees. The goal is to form complete horizontal lines of blocks, which will disappear and clear some space. The game gets faster and harder as you progress, and ends when the blocks reach the top of the screen.

Tetris is a simple but addictive game that can keep you entertained for hours. You can choose from different modes, such as classic, marathon, sprint, or ultra, and adjust the difficulty level according to your preference. You can also customize the appearance of the blocks, the background, and the music. Tetris is a game that appeals to people of all ages and backgrounds, as it tests your creativity, strategy, and reflexes. Tetris is more than just a game, it is a cultural phenomenon that has inspired countless variations, adaptations, and tributes.
