Normal Sudoku rules apply.
Yin Yang: Shade some cells so that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected. Each 2x2 area of the grid contains shaded and unshaded cells.
Hot/Cold: The value of a shaded cell is one more than it's digit. The value of an unshaded cell is one less than it's digit.
Arrows: Values along an arrow sum to the value in the attached circle.
Kropki: White dots separate cells with consecutive values. Not all dots are given.
"Cruel-sum Samurai" by AnalyticalNinja

SudokuPad: https://sudokupad.app/kvjejy6vxg
Each of the overlapping 6x6 grids contain exactly 6 digits from 1-9 to be placed within the rows, columns, and boxes without repeating. Not all grids will use the same set of digits.
Region sum lines: ALL of the lines in this puzzle are region sum lines, and contain the same sum within each box the line passes through.
Additionally, these rules apply:
German whisper lines: Adjacent digits along the bright green lines must differ by at least 5.
Renban lines: Purple lines must contain a non-repeating string of consecutive digits.
Entropy lines: Every set of three consecutive cells along the peach lines must contain a low [123], middle [456], and high [789] digit.
Modular lines: Every set of three consecutive digits along the dark green lines must contain a different residue mod 3. [147][258][369]
The grey line is a palindrome and reads the same from either direction.

Snake and Eggs—Sizes 1 to 5:
Draw an orthogonally-connected, 1-cell wide snake that does not branch, does not loop, and does not touch itself orthogonally (but may touch itself diagonally).
The remaining non-snake cells form five distinct orthogonally-connected areas (eggs), one each of sizes 1 to 5.
Areas of different sizes do not touch orthogonally, but they may touch diagonally.
Each number in the grid must be part of an area of that size.
