Clickable turn based board game

Hello! I want to start a project that would be a multiplayer turn based board game and clickable. The spaces would need to be non-simple shapes. I really have NO idea where to start on a large project and would love any suggestions.


I am kind of new, so I don’t know what to suggest.

Would a scaled-down project like this ( help you figure out how to set up a board with irregular borders?
