Boundary Atelier
Minority Maps
Same voters. Different boundaries. Can you turn a minority into a seat majority?
How to play & credits
Every square is one fictional voter, A or B. Paint the whole map into equal-sized districts. Squares in a district must connect along edges; corners do not count. A wins a district with more A than B voters. Win by giving A a majority of the districts, even though A has fewer voters overall.
Use 1–7 to choose a district, 0 to erase, Tab and Enter to paint, arrows to move around the board, U to undo, H for a hint. You may repaint any square. Hints reveal one square from a verified solution; alternate solutions also count. A hint marks the completion as guided. Progress saves on this device.
