Sudoku-More Than a Craze?

Sudoku is the newest puzzle craze in the United States.I am an analytical person, so I thought I would give the simple 9x9 grid a try.The game itself is unique, challenging and fun.The 9x9 grids ask you to fill in numbers 1-9 in each line, not to be duplicated within the line or smaller grid in the larger grid.The book quality was okay, the pages were a bit hard to erase from when I would make a mistake, but otherwise the quality was good.

The book offers different levels of play, from "Light and Easy" to "Beware!Very challenging," with all the answers in the back (in case you get stuck I assume).I started out in the easy pages, but quickly learned the strategy of sudoku to move ahead to moderate and found a whole new game.I had to study those grids hard and long before making my choice of number to fill the square.I did almost all of the moderate puzzles (with some help from the back!) before trying to take on the challenging puzzles.Those took even longer!I have yet to finish one of the beware puzzles, but know with time and patience, I should be able to before long!
