Kakuro is based on partitions of integers

AI Thread Summary
The discussion centers on the comparison between Sudoku and Kakuro, with participants noting that Kakuro is generally perceived as more challenging than Sudoku. Kakuro requires players to memorize possible number combinations, which adds to its difficulty. A specific example highlights that while making a total of 3 with two cells has one solution, making 30 with four cells also has a unique solution (6, 7, 8, 9). Participants express a preference for Sudoku due to its more straightforward completion process, but there is curiosity about the availability of Kakuro games online. Suggestions indicate that searching for "online Kakuro" could yield various platforms for play.

Does anyone do these? Sudoku is based on magic squares, Kakuro is based on partitions of integers. I haven't really tried solving any yet but my first impression was that Kakuro is generally tougher than Sudoku (for me anyway).

Yes I agree that Kakuro is harder. Kakuro was introduced to me by someone here (mattmns I believe). It helps to memorize some of the possible combinations of numbers. For example if you have to make a 3 with two cells there is only one possibility. But not so immediately obvious is that to make 30 with 4 cells there is also only one possibility - 6, 7, 8, 9. etc.

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
