How to play:
Nonograms board is a square grid. Each cell on the grid can be either on or off.
The top and left edges of the grid contain hint numbers. The hints describe the chain of connected marked cells that appear in the row or column. For example, if the hints for a row is 3 2, it means that the row has three consecutive cells marked, followed by at least on non-marked cell, and the two consecutive marked cells.
The puzzle is solved when all the cells are filled-in correctly.
Use the X to specify that a particular cell cannot be marked.
