The basic rules of Colonist.io
When you roll the dice, you'll be given the resource with the corresponding number on the map. You can use the resources to build settlements, cities, roads, and development cards. The development cards give you knights that build your army and rob opponents. If you're missing an important card, you can trade with other players and the bank. Building settlements by the port will give you a better trade deal in the resource offered.
The end goal of Colonist.io is to reach 10 victory points. You can achieve this with the number of settlements, cities, longest roads, largest armies, and VP cards. Keep that in mind!
