Canal View is played on a rectangular grid. Some of these cells have numbers in them. The aim is to blacken some cells of a grid according to the following rules:

• All black cells create a single connected group.
• No 2 x 2 cell area within the grid can contain all black cells.
• Numbered cells must not be black.
• Each numbered cell indicates the total number of black cells connected vertically and horizontally to that numbered cell, in a straight line till the next white cell, or the edge of the grid.
