In Tetris, players have to stack blocks of varying shapes and sizes as they drop from above. The goal is to stack them in a manner that connects them to each other, forming complete horizontal lines across the screen. Once a complete line is formed, it disappears. Players score points depending on how many lines they can remove at one time. Players must continually construct these disappearing lines to keep their stack from getting too big. If the stack reaches the top of the screen, it’s game over. Tetris is a classic puzzle game with no inappropriate content, and has different difficulty levels so players of any skill can enjoy the game. It is recommended for kids ages 6 and up.
