New Suduku

When I was at the airport the other day, I saw a booklet with puzzles, very much like Suduku but you needed to do additions etc It started with an 's'. Can anyone help me?

I love those and the Daily Mirror used to do one each saturday but have dropped it

The Times 2 does one each day. I never really got my head round them to be honest.

I see the site mentions that Take a Break calls them Killer Sudoku; they're available in the Times under that name too. If you've been following the Times Online and gave up when the Killers stopped appearing, then you might like to know they're back (but you'll need a recent browser, otherwise the puzzles don't render correctly).

I can heartily recommend KenKen (also in the Times) as well; they're only six-by-six in size but they've got the same sub-problems as their "fiendish" level Sudoku and their "deadly" Killers.

This sounds like the one they call KenKen in the Daily Mail pull out supplement every day but KenKen uses only the numbers 1 to 6 and is not too difficult

There is also one in the Sunday Telegraph. I can manage to do most of the "gentle" ones but I find the more difficult ones out of my league.

Squarebear/foxyface,
As well as the small-box totals you are given in a Killer puzzle, you will (spoiler alert) need to take the rows/columns/blocks having a total of 45 into account as well. All the other rules from classic sudoku come into play as the difficulty increases, with the addition of having to solve "this box/these boxes total <x> more than this box/these boxes".

For a significant challenge, check out Killer Sudoku Online: their "mind bending" puzzles *truly* deserve the name!

Well, I'm having a go but it isn't easy...
