Today’s GAS raises the temperature a bit with a combination of Thermo-Sudoku and the puzzle genre Skyscrapers.

PDF

or solve online (using SudokuPad)

Theme: High Rising Temps

Author/Opus: This is the 41st puzzle from Philip Newman, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). Some thermometer shapes are in the grid; numbers must be strictly increasing from the round bulb to the flat end. Also, as in the puzzle Skyscrapers, each number in the grid represents the height of a building and the clues on the outside of the grid indicate how many buildings can be “seen” when looking from that direction. Taller buildings block the view of smaller buildings. For example, if a row contained the numbers 198432675, then two buildings are seen from the left – 1 and 9 – and four buildings from the right – 5, 7, 8 and 9 – with the other buildings blocked by taller buildings in front of them.

GAS Time Standards (highlight to view): Two party hats (🎩🥳): 7:00; One party hat (🥳): 13:00. All other solvers earn a 🦕: Built Bashunosaurus.

Thomas Hits the GAS (highlight to view): 2:50, with SudokuPad replay file shared as a download for now (requires loading via settings menu with improvements expected before people should use this regularly).

Solution: PDF and solving video with explanation from GAS team.

Update: 2023/07/27 – We have opened up a few more of our subscription puzzles to give people a sense of what they may be missing if they aren’t a subscriber. This “warm-up” Thermo-Sudoku is a great example of some of the new easier puzzles that happen every day (alongside harder content) to get solvers back into our different genres; all warm-up puzzles are fair and interesting, even if on the easier side.

Mastering Thermo-Sudoku requires combining number placement thinking with greater than/less than thinking. How will you do on this puzzle from Serkan Yürekli that splits the numbers and the thermometers apart?
