Tutorial for beginners

Let's solve a Nonogrid puzzle, step-by-step.  By working through this puzzle, you'll see how the clues and logic can be used to deduce the color of every square.

Example:



Step 1:
The first and fourth rows have the clue 3. This means there is a group of 3 blacks. Since there are only 3 squares in total this means that each row is filled with black squares. Set these squares to black by left-clicking on them with the mouse.



Step 2: 
Notice the third column has the clue 2,1. This means that there is a group of 2 blacks, a gap and then 1 black. Since the first square is black from Step 1 the next one down must be black because the clue is 2,1. The number 2 has to apply to the top two squares, so they should both become black. 
The third square now must be white, because there has to be a gap between the top two blacks and the bottom black. Set this square to white by right-clicking on it with the mouse.



Step 3: 
The second column has the clue 1, 2. Since the first square must be black from Step 1, the next square must be white because the clue is 1, 2, Thus the third square down this column is black.



Step 4:
The first column is practically solved already. The clue is (1,1) and the position of 2 black squares was determined in the previous steps. All that needs to be done is fill in the white squares. 

Congratulations you've solved your first Nonogrid puzzle!
