Yajilin is a Japanese logic puzzle from Nikoli: draw a single closed loop through a grid while placing black cells that satisfy the arrow clues.
HOW TO PLAY
Each numbered arrow tells you how many black cells lie along its ray. Black cells can never touch each other, not even diagonally. Every remaining cell must be part of one single loop that never crosses or branches. When the black cells satisfy every clue and the loop connects every open cell exactly once, the puzzle is solved.
FEATURES
- Endless mode with a steady Easy, Medium and Hard rhythm, so puzzles never run out.
