Occup4fun is a fun classic game where you will play against online opponents for free. The objective is to conquer as many squares as possible. You need to dominate areas around the base to expand your territory and rank up. Each map can contain up to 20 players at once. Once you defeat these people, you will have the chance to control the top spot. But, it is not simple to occupy neighbors. You can start by doing the same for neutral blocks. Good luck!
