Classic Dungeon - Nonogram Tutorial

Use this tutorial to learn some basic nonogram solving strategies!

In this example, we first crossed out all of the cells on the 0 row (higlighted green).
After crossing the row out, we can eliminate the cells beneath it, when the column's last
number is greater than 3 (highlighted red). After using this basic elimination technique,
we can fill some cells in like this:

Our last elimination leaves only one place to fit 7 cells for the last 3 rows. After completing
the rows, we can eliminate the other remaining cells. These moves are highlighted in green.

When you have rows or columns with large numbers, you can count that many cells
inward from the boundaries to check for overlapping cells. This concept is illustrated above
with arrows and blue color coding. The area where there is overlap can be filled in because
there's no way not to include those cells, given the hint value.

Simply practice these basic strategies for awhile and you'll be
solving difficult Nonograms before you know it!
