This puzzle was against Matryoshka X which was voted by Scojo's twitch chat as the "real" Timotab puzzle. Well played, TVDK!
- Normal Sudoku rules apply: place the digits 1 to 9 in every row, column, and box, once each.
- Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected and no 2x2 area is fully shaded or unshaded.
- Digits cannot repeat in cages, and must sum to the value in the top left corner of the cage, if given.
- Cage totals indicate how many cells of the same colour (shaded or unshaded) are seen orthogonally from the position of the cell marked with the diamond, including itself. The other colour blocks vision.
- Cells separated by a white dot are consecutive. Cells separated by a black dot are in a 1:2 ratio
- All dots lie on the border between the shaded and unshaded regions.

Yup, need multiple iterations. But there is proper flo w and unique solution.

Great puzzle from start to end.
Setting was just incredible.
100% justified to have 100% rating.

Solved, great puzzle! It says my solution code is wrong though…

Did you follow the code instructions carefully? If so, that would suggest you have the yin-yang colouring incorrect.

Fun puzzle that didn’t break in the way I expected! I had not seen these Cave Killer Cages before, but I really like them! Especially since they allow cave clues greater than 9. Nicely set!
