In the new country, Perfectland, nothing is imperfect. This is one of my newest inventions. Rules follow:

The grid contains one or more of three symbols, each representing living spaces. The task is to divide the grid along the gridlines into regions that enclose exactly one of each of the three symbols, so that a straight line path can be drawn in each region that visits all the symbols without having to branch out, and starts and ends in one of the symbols. No region may enclose any 2x2 areas of cells. In each region, there must be at least one cell not visited by the path (representing undeveloped areas), and all such cells in the entire grid must be connected in a single group.
