I started playing, and then i realized this was a joke. So I didnt even bothered to complete a line but I didnt close the game or turn off my computer. So, after more than 24 hours, the game hasn´t finished... slowest game ever!

In order to waste time you have to be interested and this game is just pointless

Hold down Enter. It's a screensaver. And a metronome!

nobody has the patience to do this

Some keys for people who don't like pressing random keys to figure things out :
Arrows -- Kinda obvious
z & x - rotate
spacebar - fast drop
enter - super fast drop!

Or, if you press the blue "key" box and turn it red, it will change the up/down arrows to fast drop and you use z/x to rotate.
