Schedule for Next Week

All the puzzles from last week have been grouped in this PDF.

While I’ve been featuring a lot more puzzle types this year, I often get requests to go back to having more Sudoku. While my focus for many months has been organizing the 2014 Sudoku Grand Prix, now that that work is mainly done it seemed a good time to revisit the style here. So the deficit of that style won’t continue for much longer; we’ll have some classic puzzles, but not on consecutive days as that might be too many classics in a row. Even odd folks like us can appreciate a good puzzle where nothing is repeated, neighbors.

The bonus puzzle for our Expert and above patrons will be a Skyscrapers by Prasanna Seshadri.

Basement Skyscraper Sudoku by Prasanna Seshadri

PDF

Theme: Sudoku GP Round 7, plus two hidden themes related to 7
(Note: this puzzle was originally created for the Sudoku Grand Prix but after testing was judged too hard and too puzzle-based for the competition. It is an excellent puzzle, and we are proud to showcase it here.)

Author/Opus: This is the 40th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Standard Sudoku rules. Also, standard Skyscrapers rules. Additionally, the cells in grey are “underground” and cannot be seen by any of the outside skyscraper clues (think of them as starting with a negative sign if necessary). As an example, the 3 on the left of row 2 refers only to seeing three buildings in columns 2 through 9, even if there is a 9 in column 1 as that 9 cannot be seen.

Answer String: Enter the 1st row from left to right, followed by a comma, followed by the 5th row from left to right.

Time Standards (highlight to view): Grandmaster = 7:00, Master = 10:00, Expert = 20:00
