Buraitoraito 灯明
Hang lanterns in the empty cells until every numbered block sees exactly as many as it claims. A block sees straight up, down, left and right; another block stops its view, but a lantern does not — a lantern behind a lantern still counts.
Three modes: Classic; Apart, where no two lanterns may sit side by side, so every lantern needs a gap around it; and Pairs, where the opposite holds and every lantern must hang beside exactly one other.
