Game Tetris Classic

Players must move and rotate blocks as they fall, try to fit them together. If the player can actually fill the horizontal lines with color squares, the line disappears and each filled box above move down. If the player can not fill a line completely, Block will accumulate and eventually reach the top of the field. The game ends when a new block is placed at the top of the playing field can not afford to drop altogether because the block is filled. Different blocks of bricks: J-block facing the opposite direction as the L-block. S-block to fill small holes. O-block to fill a big gap. Z-block facing the opposite direction as the S-block. I-block is useful to keep four lines at once. L-block to fill a medium-sized holes.
