A: In the multi-player game, islands don’t have any requirement to be attached to other islands at all, because there are many so ways to travel between islands. Bridges are the most obvious, and there are lots of them in the game, so naturally most islands will have some Bridge connection, but of course there are also Portals.

…but besides those two literal connectors, there are three other ways to travel between islands: Ship, Gear, and Actions. So don’t worry about how you’ll get to so-called “floating” islands. There are lots of ways!

The solo game is another story, of course! That specifically calls for the creation of an archipelago with all islands linked in one grouping by Bridges.
