Only tired a few categories. I was most looking forward to assembling objects. It shows microscopic diagrams that you can't zoom in on, and asks in regular question format which will make an object of assembled. I can't see the pic, and the answers are straight up A.B.C.D. with no hints of anything else. ??? Also, a LOT of ads for games and stuff. Every screen is a new ad for color match or cartoon me.
