Hexagor.io is a game that is sort of like chess. Theres a playboard made up of hexagonals. You are given a base and from that base you are able to press on the neighboring hexagonal spaces to further gain a bigger piece of the playboard. The simple implication of gaining more space in the playboard is to build fortresses. Also, you dont have to stop there, you can hop on board with another player and work towards a common goal. Another point of the game is to make sure that your fortresses are covered. Although the best defense is an offense, it doesnt always precisely work out that way. It certainly does work, but you still need a solid defence.
