Griddler, also known as Nonogram, Picross, or Hanjie, is a type of logic puzzle that involves filling in a grid to reveal a hidden picture. The puzzle is solved by using numerical clues provided for each row and column to determine which cells should be filled in and which should remain empty.

History

The origins of Griddler can be traced back to the late 1980s. The puzzle was first created by Japanese puzzle designer Non Ishida and later popularized by the publication of similar puzzles in various magazines and newspapers. The name "Nonogram" is derived from Ishida's name.

Rules

The puzzle consists of a grid with numbers listed on the top of each column and the left side of each row. These numbers indicate the lengths of consecutive runs of filled cells in the respective row or column. For example, a clue of "4 1 3" means there are sets of four, one, and three filled cells, in that order, with at least one empty cell between each set.

Solving Techniques

Solving a Griddler puzzle typically involves a combination of logic and deduction. Common techniques include:

• Cross-referencing: Using the clues from both rows and columns to determine the placement of filled cells.
• Marking: Marking cells that are definitely filled or definitely empty based on the clues.
• Counting: Counting the number of possible filled cells and comparing them with the clues to narrow down possibilities.

Variations

There are several variations of Griddler puzzles, including:

• Colored Griddlers: These puzzles use multiple colors, with each color having its own set of clues.
• Mega Griddlers: Larger puzzles that may span multiple grids.
• 3D Griddlers: Puzzles that extend into three dimensions, adding an extra layer of complexity.

Software and Online Platforms

Griddler puzzles can be found in various formats, including printed books, magazines, and online platforms. There are also numerous software applications and mobile apps available for solving Griddler puzzles digitally.
