classic tetris. Each tetramino is made of four square blocks. Tertaminoes fall down one at a time until meet the bottom or another tetramino already laying there. Tetraminoes fall down slowly enough to let player move them to the left or to the right. player completes lines by moving differently shaped pieces (tetrominoes), which descend onto the playing field. The completed lines disappear and grant the player points, and the player can proceed to fill the vacated spaces. The game ends when the uncleared lines reach the top of the playing field. The longer the player can delay this outcome, the higher their score will be. The higher the score, the faster tetraminoes fall down. Controls are cursor keys
