Dot Fence

Slitherlink: one loop

A number in a square counts the lines around it. Draw between the dots, mark what cannot be, and one single loop appears.

WHAT YOU GET

• Campaign: 1000+ loop grids, each with exactly one answer
• Sprint: three minutes, as many loops as you can draw
• 1000+ loop grids, each with exactly one answer
• Never a guess: every board is solvable by logic alone
• Tap a line once to draw, twice to rule it out
• Numbers fade when they are satisfied
• Hints draw a line you could have worked out, or fix a wrong one
