In Sifnos you take on the role of an ancient Greek military commander in the aftermath of the Samian invasion. The mineral-rich island must be protected against pirate raids and attacks from the sea.

To do so you construct a network of beacon towers muster soldiers and invest in the island's future. The towers allow messages to be communicated quickly across Sifnos and most importantly warn of approaching sea invasions.

The game combines historical background with strategic preparation: by building defenses wisely using resources effectively and keeping the safety of the people in mind you strengthen Sifnos against the dangers ahead.
