About this game
A Japanese Nikoli logic puzzle where you shade cells according to arrow clues and draw a single continuous loop through every remaining cell.
How to play
What is Yajilin?
Yajilin is a Japanese logic puzzle published by Nikoli. The grid contains arrow clues with numbers. You must shade some cells and draw a single continuous non-intersecting loop through every remaining cell.
How do you play Yajilin?
Click cells to shade them. Arrow clues show how many cells must be shaded in that direction. No two shaded cells can share an edge. Every unshaded cell must be part of the loop.
Is Yajilin difficult?
Yajilin ranges from easy (5x6 grids) to hard (8x8 grids). Start with smaller grids and use hints. The key is logical deduction from the arrow clues.
What makes Yajilin unique?
Yajilin uniquely combines two constraint systems: cell shading rules (no adjacent shaded cells) and loop topology (single Hamiltonian cycle). This makes it one of the most satisfying Nikoli puzzles.
