Book Description

Publication Date: 12 May 2008 | Series: Kenken

KenKen is the brilliant successor to Su Doku that’s taken Japan by storm selling over one million copies in less than a year. In collaboration with The Times, Collins – the no 1 puzzle publisher – are proud to be bringing it to the UK.

KenKen is a new type of brain-training puzzle based on logic and simple arithmetic. Perfect for all ages and highly addictive, KenKen puzzles challenge and entertain in an entirely new way! The puzzle was invented by a charismatic Japanese maths teacher, Tetsuya Miyamoto in 2004. The name comes from ‘Ken’ which is the Japanese word for clever and KenKen translates as
‘square wisdom’. It’s a new type of puzzle based on simple arithmetic and each puzzle involves some or all of the following skills: addition, subtraction, multiplication and division.
As with Su Doku there are clearly defined levels for each type of puzzle from beginner and intermediate to advanced and the puzzles can be on any size grid, from 3 x 3 up to 9 x 9. The puzzles improve numeracy, logical thinking, concentration and perseverance.
Can you KenKen?

2.0 out of 5 stars No multiplication or division 27 Dec 2008
By rickyk
Format:Paperback
Although I enjoyed the first Ken Ken book, the puzzles in the second only involve addition and subtraction making them much less challenging. This is not made clear in the product description.

3.0 out of 5 stars Simpler Puzzles 17 July 2009
By Graham White
Format:Paperback
I agree with the other reviewers.

Ken Ken is a puzzle type most suited to teach children mathematics, although admittedly for this it would be very good. However, they are simply not challenging enough nor diverse to occupy most serious mumber puzzle enthusiasts for long. Most puzzles can be solved in 5 to 10 minutes, just enough to last a couple of underground stops only!

The book is well-produced and at £4 is good value for money, if this is what you are looking for.

I love the math aspact of these puzzles... and this book has real simple to quite difficult!!! However, one cannot find Ken Ken anywhere... this book was 1 of 3... But 2 and 3 are not available. I liked it so much I have bought this book twice...Ken Ken burst into my life in Jan 10 - but it only lasted 2 months... I tracked down one book company and they dropped it.... Dang Shame coz I love these puzzles more than Sudoku now!

2.0 out of 5 stars Not as good as book 1
I bought this book after thoroughly enjoying the first book in the series. To my disappointment it didn't have any multiplication or devision, which made it less fun in my opinion. Read more

4.0 out of 5 stars Good games
A very good alternative to Sudoku, personally i prefer it. You can do it quicker, but it is still challenging, for while it is only a 6x6 square grid, it's complexity makes it... Read more

I found this book contained too many simple puzzles which did not tax my brain especially after completing book 1. Read more

3.0 out of 5 stars No puzzles with multiplication or division
The puzzles only have addition and subtraction, which is a bit of a let down. I would have preferred to have had at least some of the puzzles contain multiplication and division. Read more

This is my first experience of KenKen. I started with ordinary sudokus (The Times Series) then gradually got bored and moved on to Killer sudokus (Times Series again). Read more

4.0 out of 5 stars Good, but not perfect
A good selection of puzzles, with an increasing level of difficulty. However, the puzzles top out at 6x6 and all puzzles contain mathematical signs as hints. Read more
