Book Description
Here's how you solve the puzzle: place the numbers 1 to 25 into the grid, one number per box, so that consecutive numbers are connected vertically, horizontally, and diagonally. The numbers around the edge of the grid tell which row, column, or diagonal contains those numbers. Sounds simple, right? Wrong! As your path of numbers snakes around the grid, you will marvel at the subtle complexity that is 1-to-25.
