Simon Vs Phistomefel
Added 2021-02-28 21:33:38 +0000 UTCOK so let's get one thing straight, this Yin-Yang Fillomino by Phistomefel is mind-bendingly brilliant. How on Earth did he come up this?! And can Simon figure out how to solve it? You can watch at the link below. You can play the puzzle here:

Rules are as follows:
Divide the grid into areas so that each cell contains a number that indicates the size of the associated area. Areas of the same size must not be vertically or horizontally adjacent. Given numbers can belong to the same area. There may also be areas without a given number. The areas must be divided into two groups (eg white and black) in such a way that white and black cells satisfy the Yin-Yang rules ie all cells of the same color must be orthogonally connected and no 2x2 area may be completely covered by one color.
