Logic Masters Deutschland e.V.

Speed Run Slowly, To Win

(Published on 13. August 2025, 03:00 by Will Power)

Normal Sudoku rules apply. SLOW THERMOS- Numbers on thermos must not decrease from the bulb end. Note: The SudokuPad and F-Puzzles tools cannot check slow thermos. Incorrect cells will not cause an error to show. I used circles and lines to simulate thermos. KILLER CAGES- Numbers in cages sum to the number in the top left corner of the cage. Post your time on Logic Masters Deutschland, if you like. Bonus for less than 10 minutes. Double bonus for less than 8 minutes.

12:58, I'm not that great at speed stuff, but I had fun while it went! The slow thermo took some adjusting to make sure I paid attention to box rule logic too!
