Sinker is a creatively designed map for Timberborn, measuring 128x128, set within an ocean sinkhole surrounded by breathtaking waterfalls. This map emphasizes aesthetic building and strategic gameplay, offering a compact yet engaging environment for players. It features a variety of water sources, including negative strength water sources that prevent flooding, ensuring a stable gameplay experience even during droughts. The map invites players to explore different building strategies while managing water resources effectively.

The Sinker map also introduces optional challenges to enhance gameplay, such as avoiding the construction of dams and floodgates, or the collection of all maple oak trees. An update to version 2.0 ensures compatibility with the latest game features while maintaining the original charm of the map. Players can enjoy unique challenges while appreciating the visual appeal of the sinkhole environment.
