Stay On Target
(Published on 14. February 2023, 02:51 by ViKingPrime)
PUZZLE:
RULES:
Normal Sudoku rules apply.
• Diagonal: Digits along each diagonal must not repeat.
• Killer: The value of digits within a cage must sum to the number given in the top-left corner and digits must not repeat within a cage.
• Thermometer: The value of digits along a thermometer must increase from the bulb to the tip.
MODIFIERS:
• Möbius: Each separate instance of the digit 1 may be considered as having the value of either 1 or 10 (but not both).
INTRODUCTION:
This is another exploration of a particular modifying constraint, which I like to refer to as "Möbius" (since the 1 is in effect wrapping around to join up with the 9!).
An example puzzle will follow to better illustrate the rules.
Have fun!

Lovely solve path, and agree with the comments about the möbius not being too scary - good Möbius intro for newbies.
Thanks again for the great puzzles

Cool puzzle with a nice twist, I could see how this modifier might get very tricky very quickly...

Great puzzle, fun to solve. Regarding the rules I wasn't completely sure if digits were allowed to repeat in cages or not, maybe specify that in the rules.
EDIT: Fixed! I have learned a valuable lesson today about posting puzzles on three-hours worth of sleep XD - VKP

Very interesting constraint!

The graphics contain diagonal lines but the rules do not mention this. If the diagonals must have unique digits, it would be nice if the rules clarified that.
EDIT: it was listed in the links but I must have spaced on updating the page! I'm so sorry, should be correct on Logic Masters now - VKP

Very nice, the mobius constraint wasn’t too intimidating in this one. I enjoyed it throughout, thanks!
