Tutorial

The best way we can going about solving a nonogram is by actually doing it. The following example is a nonogram in my site. I've labeled the columns as numbers and the rows as letters, this should make it easy for you to follow each step I take. There is no right or wrong way of solving nonograms and often I find new ways of solving them, and as you get used to them you will too. hello people who can't see this applet, and tough luck

Step One

We can see that there are two numbers at the right that are 15, there are only 15 squares in the length of that row. This means that all 15 of these squares can be filled in. (in other words fill rows H and J with black squares).

Step Two

The next step is also self evident. In order to solve the nonogram in the quickest amount of time we need to look at black squares near the borbers. Where we have these squares we can fill in the the number with the relevent number on either the row or column.(in other words in column 15, the number at the bottom is 1, this means that the space above must be a dot. The same is true for column 14, but for 13 and 12, the lower number stretches to 3, so square i12 and i13 need to filled in, with dots placed in g12 and g13. The same is true for i3 and i4, with dots placed g3 and g4. So now fill in i5 to i11 along with i1 and i2 with dots)

Step Three

We use the same logic as step 2 for this step, as we can see there are also a large number of blue squares in row h. (in other words fill in a1 to g1, a10 to g10 and d15 to g15 with black squares. Then fill in the rest of row i with dots, and finnish with a dot on at c15)

Step Four

Now we can see that there are 3 black seperate squares in row e and f if we look at the numbers next to those rows, we can see that there are no more black squares in those rows. This means that the rest of the rows can be filled with dots. I row d we can see that there are three seperate numbers, but the last number is a 2. From this information we can deduce that d14 must be a black square, and the other squares in that row must be dots (in other words fill in f2 to f9, f11 to f14, e2 to e9, e11 to e14, d2 to d9 and d11 to d13 with dots. and d14 with a black square)

Step Five

We can now see that row a can be filled in (and indeed could have been filled in before the previous step), and also the rest of row b can be filled with dots. (in other words fill in a2 to a9 with black squares, and a11 to a13, b2 to b9 and b11 to b13 with dots).

Step Six

This is the last step. We can see from the numbers at the bottom (i.e. column 2 to 9) have been satisfied, meaning that dots can be placed where there are empty squares. This leaves only 5 spaces left, and if we look in row c we can see the 5 spaces we are looking for.. YIPEEE. (in other words fill in c2 to c9 with dots and c11 to c14 with black squares)
