Nonograms, also known as Picross or Griddlers, are logic puzzles that involve filling in a grid to reveal a hidden image. Each row and column has numerical clues indicating how many consecutive cells should be filled in. If you’re new to Nonograms, follow these steps to get started.
Step 1: Understand the Clues
The numbers on the top and left side of the grid indicate the groups of filled squares in each row and column. For example, a clue of “3 2” means there are two groups: one with three filled squares and another with two, separated by at least one empty square.
Step 2: Find the Obvious Fills
Begin with the longest clues. If a row or column has a large number relative to the grid size, you can immediately fill in certain squares. For example, in a 10×10 grid, a clue of “8” guarantees at least the middle 6 squares will be filled.
Step 3: Mark Empty Squares
If a row or column has no clues or if you’ve placed all required filled squares, mark the remaining cells as empty. This helps you avoid mistakes and focus on solving the puzzle logically.
Step 4: Use Logic to Progress
Look for intersections where filled squares must be placed based on existing clues. Cross-check rows and columns to narrow down the possibilities. If you’re unsure, leave the cell blank and return to it later.
Step 5: Double-Check Before Finishing
Before considering the puzzle solved, verify that all clues match your solution. If something doesn’t align, review your placements and make adjustments.
With practice, solving Nonograms becomes easier and more intuitive. Start with small grids and gradually work your way up to more complex puzzles. Happy solving!
