Logic Masters Deutschland e.V.

For the Summer

(Published on 5. December 2025, 13:43 by Calvinball)

I was really happy with how this 6x6 turned out, thanks to everyone who tested and encouraged me to share it here.

If you have any questions feel free to DM me on Discord.

Happy solving!


Rules:

  • Normal 6x6 Sudoku rules apply. Place the digits 1-6 exactly once in every row, column, and 2x3 box.
  • Ambiguous Thermos: Digits strictly increase along the gray lines from bulb to tip. The bulbs of the lines need to be deduced by the solver. The bulb will always be on one end of the line, never in the middle.
  • Little Killer: Numbers outside the grid are the sum of the digits pointed to along the indicated diagonal. Digits are allowed to repeat along those diagonals as normally allowed by the other rules.
  • Solve on Sudokupad

Took me a shameful 45 minutes as I got to the end and had to start over due to an unknown mistake (I blame being on a stressful phone call while solving lol), but great fun (and made the stressful call less anxiety-inducing!)

Truly a great puzzle.

I almost rated it two stars, because for a true beginner this would be quite the challenge. (Speaking as someone who’s not a true beginner but didn’t have much luck at first.)
