In Seeland, you're transported to the Dutch Golden Age of the 17th century, a period of immense prosperity and expansion for the province. Your mission? To help reclaim land from the sea, a truly impressive feat! Taking on the role of an influential burgher, you'll actively participate in this land reclamation process.

The game board is divided into three main sections: a scoring track around the edge, a rondel for collecting seed tiles (like cabbage, rapeseed, and tulips) and windmill tiles, and the central land area where you'll place these tiles to score points. Setup involves randomly placing some 'island' tiles on the map, and you begin by placing your initial windmill pawn in the center.

The rondel has a unique way of offering tiles: when you choose a seed tile, it must be placed adjacent to one of your windmill pawns. If you opt for a windmill tile, it goes on an empty space next to an already placed tile. Each tile has a victory point value, and surrounding a windmill with other tiles is key to scoring. The scoring system is nuanced: having at least two types of adjacent seeds earns points, with a bonus if all three types are present. Placing a windmill near island tiles allows you to flip them, revealing seeds or even farms, which can grant you a coin for an immediate extra turn!

The game progresses towards its end when either the supply of seed tiles or windmill tiles is exhausted. The player with the most points at the end, including any potential endgame bonuses, wins this contest for Seeland's expansion.
