Puzzle by Nikoli S: Yajilin

About

Yajilin asks you to draw a single closed loop that never crosses itself while painting specific cells black. You get clues from numbers sitting outside the grid, which tell you how many black cells you see in that direction. The loop must pass through every numbered cell without stopping or branching off. Your goal is to find the one valid path that satisfies all the visible counts and leaves no loose ends. It feels like a tight logic puzzle where every decision locks in the next move. This title brings Nikoli's sharp design style to a browser format without any fluff. Players on our platform rate it highly for its clean rules and satisfying deduction flow. The challenge scales up as the grid gets bigger, forcing you to keep track of multiple constraints at once. There is no hand-holding here, just pure logic that rewards patience and careful observation. Most users finish a run feeling like they solved a real brain teaser rather than just filling in boxes.
