Honey, I Shrunk the Phistomefel Ring
(Published on 21. July 2024, 21:16 by Flash Groudon)
Normal sudoku rules apply. Place the digits 1-9 once each in every row, column, and 3x3 box.
Imposter: Shade exactly one cell in every row, column, and 3x3 box. The value of an unshaded cell is its digit. The value of a shaded cell must be deduced by the solver. The shaded cells form a complete set of the digits 1-9 and a complete set of the values 1-9.
Killer: Values in a cage sum to the total given in the top-left corner of that cage. Values can repeat within a cage, though digits cannot.
Kropki (+): Values separated by a white dot are consecutive with one another. Values separated by a black dot are in a 1:2 ratio with one another. Not all dots are necessarily given.

Lovely break-in, quite hard to find your way through the middle of the road until you see the end of the path. But I enjoyed each step. Thank you very much for sharing.

Quite challenging but exceptionally satisfying, loved it! I absolutely adored how the layers of logic built up from start to finish.
