From the 2013 Bookshelf:
I love logic puzzles and games like Sudoku, so Number Cross Puzzles intrigued me from the first look. I’ll admit that at first glance, Number Cross Puzzles does look a bit overwhelming since the starting point is a little harder to come by than in other number games. But after you have the first one under your belt, it clicks and you’re off to the races.
