1. Normal Sudoku rules apply (put the digits 1-9 in each row, column, and 3x3 box).
2. Little Killer: For every clue outside the grid, digits along the indicated diagonal sum to the given number.
3. Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.
4. Killer Cages: Digits cannot repeat in cages, and must sum to the value in the top-left corner if given.
5. Each cage must be fully shaded or unshaded. Each shaded cage must sum to a prime number. Each unshaded cage must sum to a square number.
6. Each cage has a unique sum.

Congrats on the fun debut! While the Break-in is fairly approachable, the sustained difficulty throughout warrants a 4*-rating I think ◡̈

Reworded the shaded/unshaded cage restriction to clarify that each cage INDIVIDUALLY needs to sum to either a prime/square number respectively.

Very nice! Some very clever deductions required, so I gave it 4 stars. The wording of the sum of the cages was a bit confusing: at first I thought it meant the sum of all the cages together, which made the puzzle impossibly hard, so I assumed it meant each cage individually. which appeared to be the case. Thanks!

Author reply: wonderful to hear you enjoyed it! I am quite new to setting (First one here, first big variant) so I was unsure of the difficulty. Edited the cage sum restriction based on your feedback.
