Equality Cages 123: A multitude of constraints by gUBBLOR & Jasura https://link.sudoku-sleuth.com/EqualityCages123

Rules:

Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

Equality cages: Cages must have an equal number of low (1,2,3,4) and high (6,7,8,9) digits AND an equal number of even (2,4,6,8) and odd (1,3,7,9) digits. Equality cages can never contain 5. Digits may not repeat in a cage.

Between line (box 1): The cell between the two filled circles must have a value between those in the circles.

Thermometer (box 1+2): Digits along the thermometer must increase starting from the bulb end.

Palindrome (box 1+4): Digits along the palindrome line read the same forwards or backwards.

Arrow (box 1+4): The digits along each arrow must sum to the digit in the circled cell.

Region sum line (box 2+3): Digits along the region sum line have the same sum in both boxes.

XV (box 3+5): Adjacent cells connected with the X must sum to 10. Adjacent cells connected with the V must sum to 5.

Nabner (box 3+6): Digits on the nabner line may not be consecutive, and must not repeat.

Parity line (box 4+7): Adjacent digits along the parity line must alternate between odd and even.

Renban (box 5+8): Digits along the renban line must be a set of consecutive digits in any order, and must not repeat.

German Whisper (box 6): Adjacent digits along the German Whisper line must have a difference of at least 5.

Zipper line (box 6+9): Digits an equal distance from the center of the zipper line must sum to the digit in the middle of the line.

Dutch Whisper (box 8): Adjacent digits along the Dutch Whisper line must have a difference of at least 4.

Kropki dots (box 8+9): A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values.
