In Titania players place ships on the map of Titania, collect shells, and try to rebuild towers and refurbish them with starfish. The towers are built by placing the ships next to the towers and paying with different colored shells. Each turn players have to decide whether to take cards or place ships by playing those cards; the cards are color-coded to match the ships being placed. The map shows a hex grid with all kind of symbols, showing the reward you get for building and spaces where you can build the towers.
