Boxed Sums
(Eingestellt am 17. August 2026, 08:53 Uhr von MatthewT)
Sudoku: Standard rules and box numbering apply.
Double-Value Digits: Digits matching the parity of their Box Number are doubled in VALUE: odd digits in odd-numbered boxes, even digits in even-numbered boxes. (Non-matching digits retain their normal value.)
Region Sum Cages: Box borders divide each cage into Segments. The VALUES of digits in each cage Segment must sum to the total shown in the upper-left corner of the cage. Digits may not repeat within a cage.
Region Sum Lines: Box borders divide each Blue line into Segments. Along any individual Blue line, the sum of VALUES in each Segment must be equal.
Cage/Line Correspondence: The Region Sum Lines use the same set of Segment Values as the Cages, with one distinct cage segment value assigned to each RSL (i.e. exactly one RSL has Segment Value 16, exactly one RSL has 24, etc).
Circles: A circled digit indicates the quantity of doubled digits used by Lines and Cages within that Box.
Lösungscode: Row 8, Left to Right

@palletpusher Indeed, my second. Stumbled upon CTC and variant sudoku approx 3-4 months ago. Been hooked ever since. Thanks for the kind words.

Smooth and delightful. Thank you very much! Loved the interactions
Edited to add: Wait, this cannot be only the second sudoku you've ever constructed? Astonishingly well set if true

So much fun! Absolute delight. Thank you so much
A note taking trick I use that might be helpful to other people. I outlined each cage in a color and then start each line with a segment of each color to keep track of possibilities. Once I figured out a match I colored the whole line the outline color.
