Portus

Ostia is a strategy game for 1-4 players. Players lead a large fleet to explore the ocean, trade and develop the port.
Make good use of the Mancala system to strengthen your personal board and aim for the highest honor!

The player chooses one of the six spaces on his board.
Corresponding resources will be produced for the number of ships in that space.
After that, take all the ships in that space and place them one by one clockwise.
Take action corresponding to where the last one ship was placed.
By repeating this, you can build a new ship on your personal board, strengthen your ship to a larger one, or build a building in the harbor.
