33 - Patchwork

Today's new puzz.link genre is Patchwork. This is a complicated genre, being a mixture of region division and colouring. Make sure to read the rules and consider the example carefully.

Here's the rules and example from the rules page:

Divide the grid into square-shaped regions, then shade some cells. Gray cells cannot be shaded, and are considered neither shaded nor unshaded. A number indicates how many shaded cells are in the region. Regions can have any amount of identical numbers, or none at all. Cells separated by a region border may not both be shaded or both be unshaded.

Following is three puzzles that I've made. I think today's puzzles are a bit harder than usual. If you get stuck on the 2nd one, give the 3rd one a try and see if anything you learn from it helps you out with the 2nd, or vica-versa. As a general tip for harder puzzles: keep an eye out for places where you need to avoid having two of the same color separated by a border. They can sometimes be hard to spot.

Something I really ought to do at some point is rethink my difficulty rating system. There's a glut of  puzzles that I give 3 Krows. I need a cleaner way to distinguish between them.

Anyway, enjoy!
