Draw one closed loop. Use the numbers as clues. Never guess. Slinkora is offline Slitherlink — the Nikoli classic also known as Fences. Sixty boards, each solver-checked to a single solution. No forced timer. Every level is open from day one. • 60 unique-solution boards across four packs: Tutorial, Easy, Medium, Hard • Clear all 60 to unlock Endless — fresh loops generated on your device • 3 guided tutorials, then pure logic • Tap between dots to draw a line; long-press to mark × • Stuck? A hint fixes one edge — a line you’re missing, or one you drew by mistake • Colour-blind mode and single-step undo • Ads only after your first 10 clears, and only when you leave a finished board One loop. Pure logic.
