Book Description
The sudoku craze keeps growing, with no end in sight--and as its popularity builds, fans keep an eagle eye out for fresh formats featuring their favorite puzzles. Here’s one sure to draw them in: sudokus that add a little spice to the mix by changing the standard 9 x 9 puzzles to 10 x 10. That means solvers get 100 squares to fill in instead of just 81! And the numbers go from zero to nine, rather than one to nine. Plus, the smaller sections within each grid are no longer 3 x 3: half the puzzles feature rectangular 5 x 2 boxes and the rest come in various random shapes, with heavy lines marking out the separate areas. It may seem daunting at first--but it’s fun!

Book Description
This challenging visual puzzle will appeal to lovers of logic and deduction brain teasers. How To Play: A map grid shows two towns, typically A and B. The objective of the puzzle is to lay down tracks to connect the two towns. Numbers around the outside of the grid tell you how many pieces of track are to be placed in each row and column. You can only use straight (horizontal and vertical) and curved (right and left) rails and the track cannot cross over itself. There is something very satisfying in the laying down of tracks. The puzzles are arranged with varying levels of difficulty, where difficulty is largely dependent on the size of the map grid (from 6x6 to 10x10). Puzzles included cover three levels of difficulty: 70 Easy, 70 Moderate, and 60 Difficult.
