Ghost Cages
(Published on 19. July 2024, 03:38 by juggler)
For an easier puzzle with invisible cages, try Trace Amounts
Normal Sudoku rules apply.
The dashed lines are part of non-overlapping retangular cages hidden in the grid. Digits in a cage do not repeat, and sum to the number represented by one or more cells in its upper left corner (read from left to right).
Example
Solution code: All the caged digits in rows 3 and 4

Very fun puzzle! It was particularly nice figuring out how the math needed to work with the cages, then being able to apply that knowledge in several ways.

Wow! This was expert level setting. A beautiful and original concept, and so well executed. One of those perfect learning and difficulty curves, where the first few deductions teach you about how the logic works, and it gradually increases until the big boss deduction at the end. Full of satisfying aha moments, that all flow seamlessly and smoothly from one to the next. 4 stars feels correct to me... I think this is the first 4 star puzzle I've ever solved on my own without asking the setter for hints, so I feel rather proud of myself right now too. Thankyou Michel for this amazing piece of work

Really nice puzzle. No idea why the rating is what it is, but it definitely should be higher.

Doesn't seem like it will solve in the beginning, but the logic slowly piles up to create this amazing puzzle. Loved it!
