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 build by placing the ships next to the towers and paying with different colored shells.
Every 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 beeing placed.
The map shows a hex grid with all kind of symbols, showing the reward you get or building spaces.where you can build the towers.
