Tinker

This achievement will unlock when you take 10,000 turns. After you have taken 10,000 turns you will need to complete a level for this to unlock. (This achievement has also been known to unlock instantly for some.)

You may or may not get this playing normally. It is possible to conquer all 7 sets without taking 10,000 turns. If you wish to "boost" this achievement, you can tape down the down arrow key and the space-bar and let it sit for about an hour or two. Come back and complete a level and it should unlock.
