Slitherlink – Loop Puzzle
One loop · daily · offline
Free · Designed for iPad. Not verified for macOS.
Numbers are the clues; the answer is one closed loop. A quiet logic puzzle
drawn like pen on paper, with a new Daily Puzzle every day.
Slitherlink, the classic logic puzzle — drawn like pen on paper.
The rules are simple. Each number counts the lines surrounding its cell.
Satisfy every number while drawing one single closed loop — no branches, no
crossings — and the puzzle is complete. It looks easy, and then the logic
gets delicious.
Every puzzle has exactly one solution. Guessing is never required: every
generated puzzle is mathematically verified to have a unique answer.
Difficulty names mean something here, too — we measure the depth of
reasoning each puzzle actually needs, and only serve ones that earn their
label.
