Loop logic puzzle
Fences: free loop logic puzzle online
Draw one clean loop around a grid of numbered squares. The clues tell you how many edges to use, but the shape of the loop is yours to work out.
What you solve
Fences starts with a small set of visible numbers. Decide which grid edges become part of the loop, mark the edges you know are empty, and keep every clue balanced as the line grows.
Readable by design
Each board is built from a finished loop, then checked with straightforward deductions before it reaches you. Easy is a quick warmup, Normal is the everyday pace, and Hard adds more decisions without turning the grid into a slog.
