Do not understand!!

I have tried clicking on things trying to make sense out of this game others call simple! But I do not see what they see! Only things I could pick up were two button looking items that have letter R & W on it. Looks like a nail with no head. A chess piece with bisHop on bottom. Ive tapped everything on my cell til my fingers hurt! Nothing makes sense! Good Luck to others! No WalkThrough Found. Deleting
