This is really easy, but hard to find out :D



All you really need to do is choose "Work on the Game" (not sure if this is right, but it's the first option in game) every day and just select pieces randomly as fast as you can. I was just moving my cursor clockwise (as shown in picture) and smashing my left mouse button :D To get this achievement you need to get atleast 77 points and by doing this I got 332 points, so I'd say that you can even skip day or two.

This isn't that hard, but I hope it helps you out. So good luck with this :)
