Puzzlerium tour: Masyu (Checkerboard)


As one of the most passionate consumers of puzzles, I opine this has to be the most fun of Masyu variants. 






Theme: As many dots as black circles

RulesDraw a single loop that consists of horizontal and vertical paths through the centres of cells, and does not intersect itself or enter the same cell more than once. The loop must pass straight through the cells with white circles, making a turn in at least one of the cells immediately before or after visiting each white circle. The loop must make a turn in all the black circles, but must go straight in both cells immediately before and after visiting each black circle.

Some nodes are labelled with a black dot indicating a checkerboard pattern - the loop turns in one pair of diagonally opposite cells and goes straight through the other. Not all such nodes are necessarily labelled - meaning there possibly are unlabelled nodes following the same pattern.


About: Masyu Checkerboard was invented by Anurag Sahay in 2021.
