Tetris is one of the earliest and most popular puzzle games known around the world. Today we want to present to your attention one of the modern versions of this game called Puzzle Drops. In front of you on the screen you will see a playing field divided into cells. The lower part of the field will be filled with various kinds of objects. Upon a signal, an object of a certain geometric shape will appear at the top of the playing field. You can use the control keys to rotate it in space around its axis, as well as move it to the right or left. Having set the object in the desired position, you lower it down. Your task is to make it so that one single row of filled cells is formed. Then it will disappear from the screen, and you will get points for it. Your task is to collect as many of them as possible in the period of time allocated for the task.
