This Yajilin Puzzle was created as practice for the US Puzzle Championship 2009. Yajilin is one of my favorite puzzle types from Nikoli because it combines multiple logical elements into a single challenge. Solvers must determine the locations of black squares while simultaneously constructing a loop that passes through the remaining cells. If you enjoy logic puzzles, loop puzzles, and championship-style brain teasers, this Yajilin puzzle provides an excellent test of deduction and analytical thinking.
