Players take on the task of clearing waterlogged areas by strategically arranging falling blocks to fill gaps and create a stable surface. The goal is to clear the entire grid before water pours in, requiring players to think ahead and plan their block placement carefully.
The player's blocks fall from above, and they must use the available space to create a solid base, navigating around debris and obstacles to keep the area dry. Available space is limited, and the player must make the most of each piece to succeed.
