Griddler nonograms

Griddler is the name these puzzles go by in many newspapers and magazines, but the puzzle is the nonogram you know: shade the cells the clues call for and a picture appears. Each griddler here has one solution, reachable by logic alone, with the picture on the second page.

Picture

Abstract hides a smooth blob that solves by pure logic. Shapes hides a recognisable picture: a heart, a star, a sailboat.

Difficulty

Larger grids have more lines to track. Every puzzle solves by logic, with no guessing.

10×10, 57 filled cells. The row and column numbers are the run-lengths of the hidden picture.

Two pages: the puzzle and its solved picture. Every puzzle is proved to solve by logic alone, by the same engine as our KDP studio.

How to solve a nonogram

The numbers around the grid describe a hidden picture. Shade the right squares and it appears.

The method

1Read the clues as runs. Each number is a block of shaded squares in that row or column, and the numbers are given in order.
2Start where the numbers are tight. A long run, or several runs that nearly fill a line, leaves only one way to place them. Shade what every arrangement agrees on.
3Mark the empty squares too. Cross out squares you can prove stay blank. Those crosses often force the next shaded square.
4Cross-check rows against columns. A square shaded for a row must satisfy its column as well. Work the two together until the picture is complete.

The one rule: Each line is shaded to match its clue numbers in order, with at least one blank between runs.
What the answer page shows: Every solved picture is printed at the back, so you can check your grid.
How the grades differ: Small grids reveal a simple shape fast. Larger grids hide more detail and take more cross-checking.
Good for: Anyone who likes a picture as the reward, from quick warm-ups to a long solve.
