I was badly addicted to this years ago: http://www.jmtb02.com/ballrevamped2/

I even experimented the "Tetris effect"... You know, that thing when you are still moving your fingers and "seeing" the game, even when you're not playing.

Lumines.

What a great game.

I really wish GoG would get more arcade style games like the ones being mentioned here.

2048 is goo enough for me.

Look on my works, ye Mighty, and despair!

I think I missed a calling not going into city planing.

Mini Metro is another great game. That Freeways games looks pretty awesome.

Alto's Adventure is a beautiful game.It's simple and mindblowing at the same time.

Ha I just finished playing some more infinite levels. How are these games not on GOG??

Can get complete pack DRM-free (comes with steam key also) on Humble Store and get extra levels on the reddit page here

Rocket League. Easy to understand and learn, but has a lot of depth and hard to master. Pretty much the formula needed for any game to be addictive.
