• Normal sudoku rules apply.
• Squares contain even digits. The circle contains an odd digit.
• Black cages are killer cages.*
• Shaded cages are hunter cages.**
• A, B, and C each represent a consistent digit from 1-9, and may or may not be different from each other.

* In killer cages, digits do not repeat and sum to the number in the top left.
** Let a digit N placed in position P within a box index the cell that is position P in box N (counting boxes left to right, top to bottom). In hunter cages, the digits in cells indexed this way are listed in the top left.


"Ambiguous Mines" by by Florian Wortmann

Normal sudoku rules apply.

Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected. No 2x2 area may be fully shaded or fully unshaded.

The circles act as "minesweeper" clues. Cells containing a circle are always unshaded, and their value is the number of shaded cells in the surrounding 3x3 area (i.e. the up to eight cells that touch the circle either orthogonally or diagonally).

Each gray line satisfies at least one of the following three contraints:

(1) Between Line:
Digits on the line must lie (by value) strictly between the digits in both connected circles.

(2) Double Arrow:
The sum of the digits along the line is equal to the sum of the digits in the circles at either end of the line.

(3) Parity Bridge:
For the line, one attached circle contains an odd digit and the other circle contains an even digit. The odd digit indicates the number of odd digits along the line (not including itself), and the even digit indicates the number of even digits along the line (not including itself).


"Double Chillomino" by Math Pesto

Fillomino: Divide the grid into polyominoes so that each cell contains a number equal to its polyomino's size.
Double Choco: Each polyomino is orthogonally connected to exactly one other polyomino of its same size. These pairs must be the same shape, although one may be a rotated and/or reflected image of the other.
Arrows: Numbers on cells with arrows refer to the total amount of polyominoes seen in the indicated  direction(s). If multiple arrows in a cell see the same polyomino, it is only counted once.


"Double Compass" by by zzw

SudokuPad (conv.): https://sudokupad.app/49v73jyucc?sett...

Divide the grid into regions of orthogonally connected cells, each containing exactly two compasses. A number in a compass indicates how many cells belong to its region that are further in the indicated direction than the compass itself. A ? stands for any digit 0-9, but two digit numbers must not start with 0.
