So you can move the figures to the right or left to the arrows located on the keyboard, from the same arrows, for example, the upper one changes the rotation of the figure to another, so that it can be put more conveniently. And the bottom one in the classic Tetris online game sends the figure down at the highest speed. but you need to use it only if you are absolutely sure that you will get to the right place. Since if you pile a lot of bricks in the wrong place, in the tetris game you will be defeated when all the figures reach the very top. And this is very likely to happen if you thoughtlessly send the figures quickly down, because there will be many empty places. And when these places are not filled, in the classic tetris there is no reduction of horizontal lines, and you do not accrue a large number of points, and even worse, this leads you to lose.
