i found all the ones except gentle very very difficult, is this just how it was created or am i missing some vital solving method. Maybe tips could start to be posted soon with methods for solving

this is the best variant on su doku ive seen yet (tho samurai was amazing too, i think the times have got su dokus sussed) so i really want to learn to solve them properly

Just finished the five in the paper, though me and my Dad were solving them together, which makes it quite a bit easier - having someone else spotting ideas and confirming your thoughts makes it quicker and a lot less likely you'll make a mistake. Not tried the one on the front cover yet, don't even have any idea how hard it is.

HELP..
Times Tricky killer.

Where am I going wrong??
in the middle/middle box the two cells totaling 17 must be 8 or 9 so I pencil those in.
In the Box above(top middle) the L shape totaling 21 is either:
4+8+9 or 5+7+9 or 6+7+8 :I cant think of any other combination??
Now for my dodgy logic..how can any of those 3 options be correct as the 8,9 penciled in below stops any of them..

so where am I going wrong??

all except the 4+8+9 can be correct as the others only contain one of the 8 or 9 mentioned

this can go in a different column to the corresponding 8 or 9 meaning that it all fits

### Killer Sudoku

Think I need help too - I managed the gentle one on the back and the gentle one of the five. But have got stuck even on the moderate one - there just seems to be too many possibilities to progress any further but I don't want to admit defeat just yet

the tricky seems easier than the mdoerate tho ive got stuck on it anyway

i kept going wrong on the moderate but have got a long way on the tricky. These new su dokus really are hard

I'm sure the moderate one has multiple solutions....
I could well have made a mistake, but I got this far -

Code: Select all
`51749628324673851998352147646x9x732132xyz4967791362845632yy9754154273698879645132`

x = 5/8
y = 1/8
z = 1/5/8

There's a neat (and rather obvious) trick that makes these a lot simpler than they first appear....

Well I'm afraid my answers are sealed up in an envelope waiting to be sent off, but I'm pretty sure there's only 1 solution - I never had to guess, so as long as my logic was correct, I found the unique solution.

D'oh. You're right. Just checked it and there's a mistake. It will complete to a valid sudoku (admitedly with multiple solutions), but two of the sum-groupings would be wrong.

Bit annoyed with myself, but I guess it was only the second one I did ;)

The TIMES did NOT give correct instructions to this puzzle. I made the same mistake when I posted one here.

The rules they give are:

"The digits within the oddly shaped “inner boxes” (marked by dotted lines) must add up to the small number written in the top corner of that box. Apart from that, all the normal Su Doku rules apply."

The rule that the left out is:

-- No digit may appear twice within a single numbered area.

This puzzle is a combination of SUDOKU and CROSS-SUMS. Cross-Sums has the 'no duplicate digits' rule.

They're gonna get slammed.

### Times Rules

I don't think that's a stipulation, tso. They're sudoku puzzles (i.e. no duplicate digits in any row/column/box), and they've got additive rules. That it.

I did all five today, and absolutely loved doing them. I, too, found the Moderate one more difficult than the Tricky one. And I don't think I'll be winning any electronics -- I don't actually get the paper, and just print them from the online site.

Lastly -- and please chime in with your own comments here -- I think this awesome new way to do Sudoku is going to go the way of the dodo. There just seem to be *too much information* to make them nearly as challenging as the traditional ones. To be fair, I've done cross sums for about 15 years now, so some of the combinations (e.g. 23-in-3-boxes) come second-nature, but even when presented with this new concept...they went pretty quickly. I'd absolutely LOVE to see some of the puzzles that are harder than Deadly.

What would you call those? KillYourselfNow?
