Nanro Loop by Bryce Herdt

Nanro by Bryce Herdt

PDF

or solve online (using our beta test of Penpa-Edit tools; use the tab key to alternate between shading, number entry, and composite loop drawing modes)

Theme: Parquet

Author/Opus: This is the 23rd puzzle from guest contributor Bryce Herdt.

Rules: Variation of Nanro rules. Label some cells with numbers to form a single non-intersecting loop; no 2×2 group of cells may be fully labeled, but the loop may touch itself orthogonally or diagonally. The region boundaries divide the loop into segments, and each region must have at least one segment. Numbers denote the length in cells of each segment within a region; all numbers in a region must be the same. When two numbers from different segments are orthogonally adjacent, the numbers must be different. (Consequently, segments in the same region must not share an edge.)

Myopia by Ashish Kumar

PDF

or solve online (using our beta test of Penpa-Edit tools; in default edgex mode: left-click+drag draws line, right click marks X on edge, tab shifts to a circle shape drawing mode that can help mark the vertices with different circle choices with another tab going back to default edgex)

Theme: Circular Logic

Author/Opus: This is the 197th puzzle from our contributing puzzlemaster Murat Can Tonta.

Rules: Draw a single, non-intersecting loop that only consists of horizontal and vertical segments between the dots. Numbers inside a cell indicate the number of turns taken by the loop at the four dots around it.

Theme: Brick Wall

Author/Opus: This is the 66th puzzle from our contributing puzzlemaster Ashish Kumar.

Rules: Draw a single, non-intersecting loop in the grid that enters and exits each bold region exactly once. If a number clue is given in a region, that number indicates the exact number of cells used by the loop in the region. Unused cells cannot be orthogonally adjacent across different regions.
