On a turn, each player chooses a tile, collects the depicted ships from the reserve, optionally buys or sells one ship, then places the ships on the board. The land has five entryways, and you must start from these points or place adjacent to ships already on the board. You can’t branch the ships being placed, and if you place your first ship adjacent to another, then that first ship must be the same color as the adjacent one; otherwise you can place ships without regard to color.
After placing ships, you can either claim colored resources from land that you’ve touched with new ships this turn or build on one vacant space. To build, the space must have colored ships around it that match the ships depicted on one of the available building tiles. If you build a personal building that’s connected to others you own, you receive money equal to the number of buildings.
You can bank one ship before the end of your turn, then you can use any three resources or a pair of matching resources to purchase a specialist, each of whom has a unique power.
After all players go, you shuffle the action tiles, place them face down in the row, then reveal enough tiles at the front of the line to set up for the next turn, with the turn order being determined by the numbers on the tiles that players chose the previous turn. Once you trigger one of the game-ending conditions — e.g., no ships of one color or no more specialists — you finish the round, then count points for buildings built, specialists hired, and money on hand.
