Overview

It’s the new shape of sudoku—and it’s no square! These fun and extra-challenging puzzles come in triangles, all color-coded to indicate special spaces where numbers can’t repeat and where new rules of play come into action. Each large triangle includes nine smaller ones (just as the square grids feature interior boxes); as usual, you must place numbers one to nine in each triangle. But then solvers face some unique (and exciting!) requirements for filling in the edges, for completing the “three legs” of the inner shaded triangle, and for handling the hexagon shapes. Fans of traditional sudoku will find it irresistible!

These puzzles are a lot more fun to do than regular sudoku. They have more challenges to consider. They aren't necessarily harder just more entertaining. There are four levels so you can work your way to the harder ones after practice. Only drawback is author has not made any more books.

difficult to get the hang of, but if you want a great different type of puzzle then the same old, this book is for you. i had a blast with it once i realized how to do the triangle rather then a square puzzle. lots and lots of fun.. wish they had another besides this book- like a second edition...

Nice twist on sudoku. took me a bit to catch on, but once I did, it really challenged me in a fun, entertaining sort of way. I've worked about 15 of the puzzles and love it. the small size lets me take it everywhere - doctor's offices, hospital visits, or anywhere I have to wait for any length of time. Recommend for those that really understand sudoku and are looking for the next step to challenge them. beginners will be flustered unless they get some help (there is an online site to teach you how to do this).

If you love the original square Sudokus, you need to step up to the next level. The challenge is greater because you have to think in so many different directions at once, not just up and down or sideways. It's tough getting started, but once I did and got the hang of the rules, I can't put it down. Try it, it's a lot of fun.
