#24 - Heavy Dots

   A classic Heavy Dots puzzle. I created this puzzle on 10 July, 2021. It is the result of another prompt by Prasanna for me to set a puzzle I have no experience with. This one took a bit longer than the Seramik to create, but I'm happy with how it came out!

Difficulty: 3/5

(rules from GM Puzzles)
Draw vertical/horizontal lines between dots to divide the grid into regions. A region may contain at most one number, equal to the area of the region. No region may cover a 2×2 area. Some dots are “heavy” and have 3 or 4 lines connected to them. Black circles indicate heavy dots with exactly three lines; white circles indicate heavy dots with four lines. Not all heavy dots are given, but there can be no heavy dots orthogonally adjacent to the indicated ones. In other words, there may be only 2 lines from any unmarked dot adjacent to a white/black circle
