From the designer's website:
"The Game of the 5 Fields could be considered a version of Chess at a strategic scale. It's an abstract version of the expansion of the civilizations during antiquity.
"You will be leading your people, represented by a Queen and her Princes, and you'll try to be the first one to build a City and 5 Fields to supply food."
From the rules:
"Players must make good use of the layout of the land to be the first one to reach the final goal: build a City adjacent to a chain of 5 Fields. In an advanced version of the game, players progressively discover the board which is blank at the beginning of the game."
