I'd randomly come across this triangular Sudoku puzzle a month before and had suggested it as one of our April new things; then I had lost it, and searching it out on the night of April 9th took longer than I expected.
On April 10th, however, I was prepared to begin, and upon the below puzzle I commenced:
Instead of placing digits 1-9 in each row, column, & 3x3 square of a traditional Sudoku puzzle, this one asked for the digits 1-9 in each of the three directions towards which the puzzle stretches. Full-length rows have all nine digits; shorter rows have only a selection of these.
I consider myself no wizard at Sudoku puzzles of any shape, but this triangular mind-torque did not prove uncommonly difficult. Most difficult I found simply training my brain to look at the three directions rather than only the two of a square Sudoku.
If you're interested, check out http://www.sachsentext.de/en, where puzzle-crafter Uwe Wiedemann (author of the above puzzle) and others have published a variety of puzzles in novel formats.
Kate and I never had a chance to chat about this New Thing, so I'm not sure what her experience therewith was like. I would, however, heartily recommend the triangular Sudoku to anyone!
All the best,
Kate & Jimmy
