1How to solve 10×10
- Look at the big numbers first. In a line of 10 squares, a "7" pushed left or right always covers the middle 4 squares: you can fill them (the overlap method).
- A line whose numbers and gaps add up to 10 has only one way to fill it (for example, "4 5" or "3 3 2").
- Once a square at the edge is filled, you can fill the length of the first number from there, and the next square is empty.
The rules and how to read the numbers, with pictures, are in How to play nonograms and tips.
2How the sizes differ
Difficulty has 5 levels, set by the grid size and how many times you have to go over the lines. Difficulty 2 needs few passes; 3 needs many.
