This is a ruleset designed to be a sort of combination of Fillomino and Sudoku. Here regions play the rule of digits in Sudoku. To make it either readable or clear, I will provide two versions of the rules, a short one and a precise one. Hope you enjoy!

Fillodoku (short): Divide the grid into regions, in which all cells have the same value. Values may not repeat in any row or column unless in the same region.

Fillodoku (precise): Fill every cell with a number. Draw a region border between unequal numbers only. (Thus regions are formed as the maximal connected components of equal numbers.) If two numbers in the same row or column are equal, they must be in the same region. (Thus regions of the same number may not share a row or column.)

Counting: A region of value N indicates that there are N regions of value N.

Other standard variants: Cells on a renban line have different values than each other. Cells separated by a white dot have values differing by 1.

Click or tap the following image to play! Here is an example of possible 4 by 4 fillodoku, with the counting rule. You can see how each region "dodges" other regions with the same number in rows and columns, as digits do in the normal sudoku rules.
