Binary Sudoku is an original game designed for use in Minetest, however it is basically a board game and does not require neither Minetest nor any other software to be played (it belongs to the paper-and-pencil games category as ordinary sudoku does).

The idea of this game came to me during the long hours spent on exploration of Minetest's worlds and certainly takes the inspiration from the peculiar feel of this game, so I find it appropriate to share it with the community on this Forum.

The rules are derived from the original sudoku, with one major difference: there're no multiple digits or other symbols which have to be arranged in certain way. In binary sudoku there're only two of them, represented by blocks of white and black wool.

The board features 16x16 grid divided into 16 smaller squares. The goal is to fill it up so that in each row, column and smaller square there're exactly 8 white and 8 black blocks.

The attached example (.we file) has many solutions (it's based on a 16x16 sudoku with even and odd numbers represented by wool of different colours), but the method for solving it differs significantly from classic sudokus.

I hope you'll enjoy it. And let me know if you managed to complete it, I haven't solved it yet :|

EDIT: solution :))
