My Tetris AI playing Tetris. (and failing)

I wrote my own Tetris game a while ago and decided to make an AI for it :P
It works quite well, it has made it to around 2000 points a few times and I've only ran it for that long like 15 times.
Of course it fails too sometimes (like here). I especially found this one funny :P

Impressive!

@Benedek93 Actually it really was, I was seeding the randomizer with time(0) so at fast speeds it often had repeated blocks which gave the AI a hard time. Now I seed it with milliseconds and it has managed to get over 6000 points. :)

Actual tetris has a random bag, instead of it chosing completely random blocks fyi,

So that's what programmers do when they get bored of their games. They make a program to play it for them. :D
