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?
