Puzzle 21: Country Road 1

Decided to use the same grid I used for Shimaguni 1. May well use it for Heyawake 2 as well.

Rules for Country Road

Shade some squares and draw a continuous path through the rest of the squares so that:

• The path goes through each region exactly once.
• Any numbered cell contains exactly that number of squares on the path.
• No two shaded cells lie directly across a region border from each other.

Puzzle 20: Mochikoro 1

My first attempt at constructing this style of puzzle. Let me know if there are any other styles of puzzle you would like to see.

Rules of Mochikoro

You are given a grid with numbers in some of the cells.

Shade some of the cells dark, the others remaining light such that:

• All orthogonally contiguous areas of light cells are rectangles with sides parallel to the sides of the grid.
• There are no 2 x 2 areas of dark cells
• You can get from any light cell to any other moving only through light cells which are adjacent orthogonally or diagonally.

Puzzle 19: Hashi 1

Rules for Hashi:

• Join up the islands with bridges so that you can get from any island to any other island.
• Bridges may only go horizontally or vertically.
• Bridges may not cross each other.
• You can put up to two bridges between any adjacent pair of islands.
• Each island is numbered with the number of bridges which end at that island.

Puzzle 18: Barns 2

This one is really quite hard. There is a hint available.

Puzzle 17: Barns 1

A new Nikoli type that I have not published before: Barns.

Instructions:
Draw a single loop through all of the cells of the grid, that does not cross itself outside of the shaded area, does not change direction inside the shaded area and does not cross any thick borders between cells.
