To travel to another island, click on the Boat and choose the island you’d like to travel to. There are Temporary and Permanent islands. When you hover over an island that can be visited, a green "Travel" sign will appear underneath it:
An island may be unavailable for you to travel to for two reasons:
You aren’t at a high enough level – in such a case, the required level is indicated under the image of the island.
You have not met the conditions necessary for you to be able to visit the island – the conditions necessary are under the image of the island (clicking on the eye icon next to the conditions will provide you with a hint).
Click on the island and pick your Provisions. You can manually select your provisions using the «Pick» button under the dishes, or you can click the «Auto-select» button at the bottom of the window to take enough supplies from your Storage with one click.
The amount of supplies necessary to travel to a selected island is indicated in the Provisions bar, and the amount of supplies provided by each dish is indicated to the left of its image, under the basket icon. The dishes you choose as supplies will be used once you travel.
Have you got enough supplies to set sail? Then you can confidently cast off on your adventures by clicking the «Go!» button.
