How to play

Each turn: 1) click your islands to add your 3 supply (click again for more), 2) click one of your islands, then an adjacent enemy or wild island, to send an expedition of strength−1. You take an island when your sent strength beats its garrison; the surplus stays. Wild islands hold a garrison of 2. Or press Hold position to end your turn.
