Slitherlink is also known as Loop the Loop or Fences, and it originated in Japan in the 1990s. The game has since become popular worldwide, and there are now many variations and levels of difficulty available.

To play Slitherlink, you start with a blank grid of squares, which can be of various sizes. Some of the squares are already filled with lines, while others are blank. The goal is to create a loop that goes through every blank square, while following the rules of the game.

The rules of Slitherlink are as follows:

• Each number in the grid represents the number of sides of that square that the loop must pass through.
• The loop cannot cross or overlap itself.
• The loop must be a continuous path that goes through every blank square in the grid.
• The loop must not touch itself, except at the endpoints.
• Players must use logic and deduction to figure out which squares the loop should pass through, based on the numbers in the grid and the position of the lines. The game can be challenging, but it is also very rewarding when you successfully create a loop that goes through every square in the grid.

Slitherlink puzzles can be found in newspapers and puzzle books, and there are also many online resources available for playing and creating Slitherlink puzzles.

### Shikaku

Each rectangle contains only one number. The rectangle can be any size, as long as it contains the correct number of squares. The rectangles cannot overlap or touch each other. Players must use logic and deduction to figure out which squares should be included in each rectangle, based on the numbers in the grid and the position of the squares. The game can be challenging, but it is also very satisfying when you successfully divide the grid into rectangles that meet all of the rules.

• The loop must turn at every circle in the grid.
• The loop cannot pass through a square diagonally.
• When the loop passes through a square, it must either continue straight or make a right-angle turn, depending on the orientation of the line segments in that square.

Players must use logic and deduction to figure out which squares the loop should pass through, based on the positions of the circles and the orientation of the line segments. The game can be challenging, but it is also very rewarding when you successfully create a loop that goes through every square in the grid.

• The shaded cells cannot form a 2x2 square.
• All of the white cells must be connected to form a single, connected region.
• The shaded cells cannot form a straight line of three or more cells.

Players must use logic and deduction to figure out which cells to shade in and which cells to leave blank, based on the positions of the black cells and the restrictions imposed by the rules.
