Customer Reviews

Best Killer yet
I have already worked through the Times Killer books 1 and 2 and The Big Book of Killer Su Doku by Mark Huckvale. In my opinion this is the best yet - some real corkers to test the old grey matter.
Highly recommended.

More of the same
This is about what you would expect if you've already done books 1 & 2. The level of difficulty is up another notch and there are much fewer easy puzzles. There are also more puzzles this time - 150, compared to 110 in book 1 and 100 in book 2. Some of the final "Deadly" puzzles will test you much more than anything in the previous two books.

The next dimension of Su Doku
If you like Su Doku but are starting to find it maybe a little stale try this. These Times Killer Su Doku puzzles add a new element of arithmetical and deductional skill to the standard puzzles.
I do like the feature you get with this particular series of adding a challenge time for each puzzle but you should probably halve the time stated to make it more of a challenge. My only query would be why they could not squeeze in a few more puzzles?
