ot your pencil ready? Good. Ready for a
mental workout? Terrific. In this part, you
can choose whatever level of puzzle challenge
you feel up to, from Easy to Treacherous. And you
can tackle as many puzzles as you’d like, all at the
same time. (Doing so can ease the frustration of
getting stuck on one puzzle for too long.) So settle
into a comfortable chair, pick a page, and show
that grid who’s boss!
