--- Comment #1 from Ian Wadham <iandw...@gmail.com> ---
In Tiny Killer (4x4) and Killer Sudoku (9x9) the 2x2 and 3x3 blocks in the grid
each have to contain each digit exactly once, just as in Standard or Classic
4x4 and 9x9 Sudoku. In your attachment, the bottom-left 3x3 block has only one
place where a 7 can go. The rest of the unique solution follows from that.
See also https://bugs.kde.org/show_bug.cgi?id=421713#c1 and
https://bugs.kde.org/show_bug.cgi?id=421713#c4 for a fuller explanation.
Also the latest version of the KSudoku Handbook is due to be released this
month. It has been updated to explain the finer points of all the variants
available in KSudoku. Also you can see the raw source (docbook XML) at
https://invent.kde.org/games/ksudoku/-/blob/master/doc/index.docbook. Lines 216
to 333 cover the variant KSudoku games.
