PUZZLE NO. 302 : THERMO SUDOKU

IT'S ISC 2021

This puzzle was created by me for ISC 2021. But the testers found it a bit hard for a contest. So I am posting it on my blog.



RULES : Classic Sudoku rules apply. Additionally, there are some thermometer shapes in the grid. The numbers are in increasing order from the bulb to the flat end on each thermometer.

  2. Decent timing. Sadly, this couldn't be included in ISC.

  3. 14:57. Break-in was absolutely brutal.
    But once the spark was ignited, digits spread like wild fire. Theme is also fantastic. Without doubt one of your best sudokus in the blog !

    1. Thanks Kishore. This is one of my favourites aa well. Everything worked out well - from the theme to the difficulty level. But the test solvers found it a bit too difficult for a competition. They felt people would resort to guessing.
