What does it mean to complete a level without using any tips?

It doesn't make as much sense in this version, as compared to the first Farm Frenzy, but it apparently means not getting any red arrows . . . near as I can tell. Like when you click on the ground without water in the well or click on the well without money to buy water. It may also involve checking out the production level of the buildings by keeping the cursor over them.

It's hard to do since you generally accidentally do any of those things in the course of frantic gameplay!!
