A classic Yajilin. Shade some cells and draw a single, closed loop through all remaining white cells without it crossing itself. Clues are not part of the loop and indicate the number of shaded cells in the arrow’s direction. Shaded cells can not touch orthogonally.
Testing reports have said it's hard, but it can be fully solved without bifurcation.
