North America Territory Wars / Browser game
Every player gets a coastal capital and one job: keep it. Claim neighboring land, fight over occupied territory with a d12, and take the other capitals before they take yours.
These borders were drawn for the game, not copied from a classroom map. A territory touches what it looks like it touches. Gold dashed lines handle the sea crossings.

On your turn, choose one territory next to yours. Empty land is free. If somebody owns it, both of you roll. The last player with a capital wins.
Choose a coastal territory. That is your first piece of land and your capital.
Pick one territory touching your empire, including the sea links marked in gold.
If somebody owns the land, both of you roll. The high roll gets it. Take a capital, knock that player out, and move again.
Same board and rules. The only difference is where the other players sit.
Use one phone, tablet, or laptop. The game tells you when to hand it over. Only the host needs an account.
Make a room and send the code. Everyone plays from their own device, while the server keeps the board and dice in sync.
A local game takes one device. An online game takes a room code and a few people who answer their messages.
