Full description

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. - A daily puzzle with a monthly calendar, so you can see your streak at a glance. - A short, guided tutorial that shows exactly where to tap for every kind of clue. - Hints that never mislead: they first clear anything you got wrong, then reveal a proven part of the answer. - Undo, reset, and a clean interface with no clutter. Yajilin rewards careful reading over speed. There is no timer and no pressure, just one puzzle at a time.
