5.0 out of 5 stars Better than KenKen. September 6, 2009
By Ferd Berfal

DJAPE’s puzzles have more variety than the KenKen’s cranked out by the thousands by Will Shortz.

1) Much greater variety in the size and shape of the cages. Most KenKen stick to cages of mostly 2 and 3 cells. This makes a big difference in the experience of solving and makes the puzzles unique. Short’s KenKen can be monotonously the same.

2) Use of subtraction and division for cages of 3 or more cells is allowed. Again, greater variety is allowed by ignoring KenKen’s arbitrary self-imposed limitation.

3) Many puzzles have the few or no operators given. This makes an easy puzzle hard and a hard puzzle harder — and even when it doesn’t, it makes you feel as if you’re cleverer than you really are! And again, this adds to the variety.

4) More sizes than the typical Shortz KenKen book does. Often Shortz books are ALL 6×6, or worse, 4×4 + 6×6.

5) DJAPE is a legitimate expert in the field of Sudoku and Sudoku variants, having run a website for years, created several pieces of software and 1000’s of puzzles. Will Shortz knows *nothing* about number puzzles; his expertise is in *word* puzzles. Cripes — he calls Sudoku “wordless crossword puzzles”.

6) Other than buying this book and enjoying the puzzles from his website, I have no connection to DJAPE. I do not even know who she or he is.

5.0 out of 5 stars Killer Sudoku Squared February 21, 2009
By Ray Daniels
Format:Paperback|Amazon Verified Purchase

Even more math emphasis than Killer Sudoku, employing multiplication, division and subtraction. Sound challenging? Fortunately, he starts out with easy versions using only the numbers one through five.

Overall, I miss the use of three by three cells here and still occasionally get tripped up by the use of the same number twice within a cell. But they are engaging and a nice change of pace from Killer Sudoku.

4.0 out of 5 stars Harder than Ken Ken March 18, 2010
By E. Hart
Format:Paperback|Amazon Verified Purchase

I am only 20% through the book. I have finished several Ken-Ken books; this book is harder–which is what I wanted. I’ve switched from pen to pencil, since my ‘solution’ rate is only about 50%. This way, I can take another run at my failures.

I recommend this book for folks who want a little more challenge than Ken-Ken.
