So the question is: Does giving totals for all outer 3 cells (across and/or down) in selected 9×9 squares give the ability to solve a sudoku puzzle with a reduced collection of starting numbers?

The book by Xin-She Yang, Ph.D., called Cryptic Kakuro and Cross Sums Sudoku offers cross sums of all the 9×9 squares by creating wider detachments between them. There are no starting numbers as a result.

In other news, the 3rd Annual World Championship Sudoku Competition has just provided some downloadable materials for study and sample variations that (we and) the contestants may work on.

Sudoku puzzles can be summarized as sequences of 81 numbers from 0 (or '.') to 9. The zeroes (or dots) represent the empty cells. The other numbers represent the givens. To create the sequence simply chain all rows starting from the top, replacing the empty cells with zeroes. You can find puzzles expressed this way in other sudoku websites or, with some patience, create your own.
To import such puzzles, paste the string into the text field labeled 'Puzzle string' and press the 'Load' button below it.
The puzzle is loaded and displayed.
