Tetris is a classic video puzzle game. It's still very popular today. The object of the game is to arrange blocks in a horizontal, or vertical, position so that they don't escape the grid. As you'd expect, Tetris becomes harder as each level goes. Tetris's gameplay is simple. First, you are shown a rectangle grid of falling bricks. To get as many pieces into the area as possible, arrange these blocks so that they do NOT fall outside of it.
Tetris is a great game for your phone or tablet. You can play it wherever you are and don't need to plug in your device. The best thing about it is that you don't need to download anything. You only need a computer, an internet connection, patience, and a gadget.
